Vulnerability from osv_openeuler
The Linux Kernel, the operating system core itself.
Security Fix(es):
In the Linux kernel, the following vulnerability has been resolved:
tcp: Use refcount_inc_not_zero() in tcp_twsk_unique().
Anderson Nascimento reported a use-after-free splat in tcp_twsk_unique() with nice analysis.
Since commit ec94c2696f0b ("tcp/dccp: avoid one atomic operation for timewait hashdance"), inet_twsk_hashdance() sets TIME-WAIT socket's sk_refcnt after putting it into ehash and releasing the bucket lock.
Thus, there is a small race window where other threads could try to reuse the port during connect() and call sock_hold() in tcp_twsk_unique() for the TIME-WAIT socket with zero refcnt.
If that happens, the refcnt taken by tcp_twsk_unique() is overwritten and sock_put() will cause underflow, triggering a real use-after-free somewhere else.
To avoid the use-after-free, we need to use refcount_inc_not_zero() in tcp_twsk_unique() and give up on reusing the port if it returns false.
[0]: refcount_t: addition on 0; use-after-free.

In the Linux kernel, the following vulnerability has been resolved:
drm/amdgpu: change vm->task_info handling
This patch changes the handling and lifecycle of vm->task_info object. The major changes are: - vm->task_info is a dynamically allocated ptr now, and its uasge is reference counted. - introducing two new helper funcs for task_info lifecycle management - amdgpu_vm_get_task_info: reference counts up task_info before returning this info - amdgpu_vm_put_task_info: reference counts down task_info - last put to task_info() frees task_info from the vm.
This patch also does logistical changes required for existing usage of vm->task_info.
V2: Do not block all the prints when task_info not found (Felix)
V3: Fixed review comments from Felix - Fix wrong indentation - No debug message for -ENOMEM - Add NULL check for task_info - Do not duplicate the debug messages (ti vs no ti) - Get first reference of task_info in vm_init(), put last in vm_fini()
V4: Fixed review comments from Felix - fix double reference increment in create_task_info - change amdgpu_vm_get_task_info_pasid - additional changes in amdgpu_gem.c while porting(CVE-2024-41008)
In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: Add null checks for 'stream' and 'plane' before dereferencing
This commit adds null checks for the 'stream' and 'plane' variables in the dcn30_apply_idle_power_optimizations function. These variables were previously assumed to be null at line 922, but they were used later in the code without checking if they were null. This could potentially lead to a null pointer dereference, which would cause a crash.
The null checks ensure that 'stream' and 'plane' are not null before they are used, preventing potential crashes.
Fixes the below static smatch checker: drivers/gpu/drm/amd/amdgpu/../display/dc/hwss/dcn30/dcn30_hwseq.c:938 dcn30_apply_idle_power_optimizations() error: we previously assumed 'stream' could be null (see line 922) drivers/gpu/drm/amd/amdgpu/../display/dc/hwss/dcn30/dcn30_hwseq.c:940 dcn30_apply_idle_power_optimizations() error: we previously assumed 'plane' could be null (see line 922)(CVE-2024-43904)
In the Linux kernel, the following vulnerability has been resolved:
ALSA: line6: Fix racy access to midibuf
There can be concurrent accesses to line6 midibuf from both the URB completion callback and the rawmidi API access. This could be a cause of KMSAN warning triggered by syzkaller below (so put as reported-by here).
This patch protects the midibuf call of the former code path with a spinlock for avoiding the possible races.(CVE-2024-44954)
In the Linux kernel, the following vulnerability has been resolved:
tracefs: Use generic inode RCU for synchronizing freeing
With structure layout randomization enabled for 'struct inode' we need to avoid overlapping any of the RCU-used / initialized-only-once members, e.g. i_lru or i_sb_list to not corrupt related list traversals when making use of the rcu_head.

In the Linux kernel, the following vulnerability has been resolved:
x86/mm: Fix pti_clone_pgtable() alignment assumption
Guenter reported dodgy crashes on an i386-nosmp build using GCC-11 that had the form of endless traps until entry stack exhaust and then
DF from the stack guard.
It turned out that pti_clone_pgtable() had alignment assumptions on the start address, notably it hard assumes start is PMD aligned. This is true on x86_64, but very much not true on i386.
These assumptions can cause the end condition to malfunction, leading to a 'short' clone. Guess what happens when the user mapping has a short copy of the entry text?
Use the correct increment form for addr to avoid alignment assumptions.(CVE-2024-44965)
In the Linux kernel, the following vulnerability has been resolved:
drm/mgag200: Bind I2C lifetime to DRM device
Managed cleanup with devm_add_action_or_reset() will release the I2C adapter when the underlying Linux device goes away. But the connector still refers to it, so this cleanup leaves behind a stale pointer in struct drm_connector.ddc.
Bind the lifetime of the I2C adapter to the connector's lifetime by using DRM's managed release. When the DRM device goes away (after the Linux device) DRM will first clean up the connector and then clean up the I2C adapter.(CVE-2024-44967)
In the Linux kernel, the following vulnerability has been resolved:
s390/sclp: Prevent release of buffer in I/O
When a task waiting for completion of a Store Data operation is interrupted, an attempt is made to halt this operation. If this attempt fails due to a hardware or firmware problem, there is a chance that the SCLP facility might store data into buffers referenced by the original operation at a later time.
Handle this situation by not releasing the referenced data buffers if the halt attempt fails. For current use cases, this might result in a leak of few pages of memory in case of a rare hardware/firmware malfunction.(CVE-2024-44969)
In the Linux kernel, the following vulnerability has been resolved:
mptcp: pm: avoid possible UaF when selecting endp
select_local_address() and select_signal_address() both select an endpoint entry from the list inside an RCU protected section, but return a reference to it, to be read later on. If the entry is dereferenced after the RCU unlock, reading info could cause a Use-after-Free.
A simple solution is to copy the required info while inside the RCU protected section to avoid any risk of UaF later. The address ID might need to be modified later to handle the ID0 case later, so a copy seems OK to deal with.(CVE-2024-44974)
In the Linux kernel, the following vulnerability has been resolved:
bnxt_en: Fix double DMA unmapping for XDP_REDIRECT

In the Linux kernel, the following vulnerability has been resolved:
tcp: prevent concurrent execution of tcp_sk_exit_batch
Its possible that two threads call tcp_sk_exit_batch() concurrently, once from the cleanup_net workqueue, once from a task that failed to clone a new netns. In the latter case, error unwinding calls the exit handlers in reverse order for the 'failed' netns.
tcp_sk_exit_batch() calls tcp_twsk_purge(). Problem is that since commit b099ce2602d8 ("net: Batch inet_twsk_purge"), this function picks up twsk in any dying netns, not just the one passed in via exit_batch list.
This means that the error unwind of setup_net() can "steal" and destroy timewait sockets belonging to the exiting netns.
This allows the netns exit worker to proceed to call
WARN_ON_ONCE(!refcount_dec_and_test(&net->ipv4.tcp_death_row.tw_refcount));
without the expected 1 -> 0 transition, which then splats.
At same time, error unwind path that is also running inet_twsk_purge() will splat as well:

... because refcount_dec() of tw_refcount unexpectedly dropped to 0.
This doesn't seem like an actual bug (no tw sockets got lost and I don't see a use-after-free) but as erroneous trigger of debug check.
Add a mutex to force strict ordering: the task that calls tcp_twsk_purge() blocks other task from doing final _dec_and_test before mutex-owner has removed all tw sockets of dying netns.(CVE-2024-44991)
In the Linux kernel, the following vulnerability has been resolved:
iommu: Restore lost return in iommu_report_device_fault()
When iommu_report_device_fault gets called with a partial fault it is supposed to collect the fault into the group and then return.
Instead the return was accidently deleted which results in trying to process the fault and an eventual crash.
Deleting the return was a typo, put it back.(CVE-2024-44994)
In the Linux kernel, the following vulnerability has been resolved:
net: hns3: fix a deadlock problem when config TC during resetting
When config TC during the reset process, may cause a deadlock, the flow is as below: pf reset start │ ▼ ...... setup tc │ │ ▼ ▼ DOWN: napi_disable() napi_disable()(skip) │ │ │ ▼ ▼ ...... ...... │ │ ▼ │ napi_enable() │ ▼ UINIT: netif_napi_del() │ ▼ ...... │ ▼ INIT: netif_napi_add() │ ▼ ...... global reset start │ │ ▼ ▼ UP: napi_enable()(skip) ...... │ │ ▼ ▼ ...... napi_disable()
In reset process, the driver will DOWN the port and then UINIT, in this case, the setup tc process will UP the port before UINIT, so cause the problem. Adds a DOWN process in UINIT to fix it.(CVE-2024-44995)
In the Linux kernel, the following vulnerability has been resolved:
vsock: fix recursive ->recvmsg calls
After a vsock socket has been added to a BPF sockmap, its prot->recvmsg has been replaced with vsock_bpf_recvmsg(). Thus the following recursiion could happen:
vsock_bpf_recvmsg() -> __vsock_recvmsg() -> vsock_connectible_recvmsg() -> prot->recvmsg() -> vsock_bpf_recvmsg() again
We need to fix it by calling the original ->recvmsg() without any BPF sockmap logic in __vsock_recvmsg().(CVE-2024-44996)

This happened because fscache_cookie_state_machine() was slow and was still running while another process invoked fscache_unuse_cookie(); this led to a fscache_cookie_lru_do_one() call, setting the FSCACHE_COOKIE_DO_LRU_DISCARD flag, which was picked up by fscache_cookie_state_machine(), withdrawing the cookie via cachefiles_withdraw_cookie(), clearing cookie->cache_priv.
At the same time, yet another process invoked cachefiles_prepare_write(), which found a NULL pointer in this code line:
struct cachefiles_object *object = cachefiles_cres_object(cres);
The next line crashes, obviously:
struct cachefiles_cache *cache = object->volume->cache;
During cachefiles_prepare_write(), the "n_accesses" counter is non-zero (via fscache_begin_operation()). The cookie must not be withdrawn until it drops to zero.
The counter is checked by fscache_cookie_state_machine() before switching to FSCACHE_COOKIE_STATE_RELINQUISHING and FSCACHE_COOKIE_STATE_WITHDRAWING (in "case FSCACHE_COOKIE_STATE_FAILED"), but not for FSCACHE_COOKIE_STATE_LRU_DISCARDING ("case FSCACHE_COOKIE_STATE_ACTIVE").
This patch adds the missing check. With a non-zero access counter, the function returns and the next fscache_end_cookie_access() call will queue another fscache_cookie_state_machine() call to handle the still-pending FSCACHE_COOKIE_DO_LRU_DISCARD.(CVE-2024-45000)
In the Linux kernel, the following vulnerability has been resolved:
rtla/osnoise: Prevent NULL dereference in error handling
If the "tool->data" allocation fails then there is no need to call osnoise_free_top() and, in fact, doing so will lead to a NULL dereference.(CVE-2024-45002)
In the Linux kernel, the following vulnerability has been resolved:
vfs: Don't evict inode under the inode lru traversing context
The inode reclaiming process(See function prune_icache_sb) collects all reclaimable inodes and mark them with I_FREEING flag at first, at that time, other processes will be stuck if they try getting these inodes (See function find_inode_fast), then the reclaiming process destroy the inodes by function dispose_list(). Some filesystems(eg. ext4 with ea_inode feature, ubifs with xattr) may do inode lookup in the inode evicting callback function, if the inode lookup is operated under the inode lru traversing context, deadlock problems may happen.
Case 1: In function ext4_evict_inode(), the ea inode lookup could happen if ea_inode feature is enabled, the lookup process will be stuck under the evicting context like this:
- File A has inode i_reg and an ea inode i_ea
- getfattr(A, xattr_buf) // i_ea is added into lru // lru->i_ea
-
Then, following three processes running like this:
PA PB echo 2 > /proc/sys/vm/drop_caches shrink_slab prune_dcache_sb // i_reg is added into lru, lru->i_ea->i_reg prune_icache_sb list_lru_walk_one inode_lru_isolate i_ea->i_state |= I_FREEING // set inode state inode_lru_isolate __iget(i_reg) spin_unlock(&i_reg->i_lock) spin_unlock(lru_lock) rm file A i_reg->nlink = 0 iput(i_reg) // i_reg->nlink is 0, do evict ext4_evict_inode ext4_xattr_delete_inode ext4_xattr_inode_dec_ref_all ext4_xattr_inode_iget ext4_iget(i_ea->i_ino) iget_locked find_inode_fast __wait_on_freeing_inode(i_ea) ----→ AA deadlock dispose_list // cannot be executed by prune_icache_sb wake_up_bit(&i_ea->i_state)
Case 2: In deleted inode writing function ubifs_jnl_write_inode(), file deleting process holds BASEHD's wbuf->io_mutex while getting the xattr inode, which could race with inode reclaiming process(The reclaiming process could try locking BASEHD's wbuf->io_mutex in inode evicting function), then an ABBA deadlock problem would happen as following:
- File A has inode ia and a xattr(with inode ixa), regular file B has inode ib and a xattr.
- getfattr(A, xattr_buf) // ixa is added into lru // lru->ixa
- Then, following three processes running like this:
PA PB PC echo 2 > /proc/sys/vm/drop_caches shrink_slab prune_dcache_sb // ib and ia are added into lru, lru->ixa->ib->ia prune_icache_sb list_lru_walk_one inode_lru_isolate ixa->i_state |= I_FREEING // set inode state inode_lru_isolate __iget(ib) spin_unlock(&ib->i_lock) spin_unlock(lru_lock) rm file B ib->nlink = 0rm file A iput(ia) ubifs_evict_inode(ia) ubifs_jnl_delete_inode(ia) ubifs_jnl_write_inode(ia) make_reservation(BASEHD) // Lock wbuf->io_mutex ubifs_iget(ixa->i_ino) iget_locked find_inode_fast __wait_on_freeing_inode(ixa) | iput(ib) // ib->nlink is 0, do evict | ubifs_evict_inode | ubifs_jnl_delete_inode(ib) ↓ ubifs_jnl_write_inode ABBA deadlock ←-----make_reservation(BASEHD) dispose_list // cannot be executed by prune_icache_sb wake_up_bit(&ixa->i_state)

In the Linux kernel, the following vulnerability has been resolved:
fix bitmap corruption on close_range() with CLOSE_RANGE_UNSHARE
copy_fd_bitmaps(new, old, count) is expected to copy the first count/BITS_PER_LONG bits from old->full_fds_bits[] and fill the rest with zeroes. What it does is copying enough words (BITS_TO_LONGS(count/BITS_PER_LONG)), then memsets the rest. That works fine, if all bits past the cutoff point are clear. Otherwise we are risking garbage from the last word we'd copied.
For most of the callers that is true - expand_fdtable() has count equal to old->max_fds, so there's no open descriptors past count, let alone fully occupied words in ->open_fds[], which is what bits in ->full_fds_bits[] correspond to.
The other caller (dup_fd()) passes sane_fdtable_size(old_fdt, max_fds), which is the smallest multiple of BITS_PER_LONG that covers all opened descriptors below max_fds. In the common case (copying on fork()) max_fds is ~0U, so all opened descriptors will be below it and we are fine, by the same reasons why the call in expand_fdtable() is safe.
Unfortunately, there is a case where max_fds is less than that and where we might, indeed, end up with junk in ->full_fds_bits[] - close_range(from, to, CLOSE_RANGE_UNSHARE) with * descriptor table being currently shared * 'to' being above the current capacity of descriptor table * 'from' being just under some chunk of opened descriptors. In that case we end up with observably wrong behaviour - e.g. spawn a child with CLONE_FILES, get all descriptors in range 0..127 open, then close_range(64, ~0U, CLOSE_RANGE_UNSHARE) and watch dup(0) ending up with descriptor #128, despite #64 being observably not open.
The minimally invasive fix would be to deal with that in dup_fd(). If this proves to add measurable overhead, we can go that way, but let's try to fix copy_fd_bitmaps() first.
- new helper: bitmap_copy_and_expand(to, from, bits_to_copy, size).
- make copy_fd_bitmaps() take the bitmap size in words, rather than bits; it's 'count' argument is always a multiple of BITS_PER_LONG, so we are not losing any information, and that way we can use the same helper for all three bitmaps - compiler will see that count is a multiple of BITS_PER_LONG for the large ones, so it'll generate plain memcpy()+memset().

[CAUSE] Although I cannot reproduce the error, the report itself is good enough to pin down the cause.
The call trace is the regular endio workqueue context, but the free-by-task trace is showing that during btrfs_submit_chunk() we already hit a critical error, and is calling btrfs_bio_end_io() to error out. And the original endio function called bio_put() to free the whole bio.
This means a double freeing thus causing use-after-free, e.g.:
-
Enter btrfs_submit_bio() with a read bio The read bio length is 128K, crossing two 64K stripes.
-
The first run of btrfs_submit_chunk()
2.1 Call btrfs_map_block(), which returns 64K 2.2 Call btrfs_split_bio() Now there are two bios, one referring to the first 64K, the other referring to the second 64K. 2.3 The first half is submitted.
- The second run of btrfs_submit_chunk()
3.1 Call btrfs_map_block(), which by somehow failed Now we call btrfs_bio_end_io() to handle the error
3.2 btrfs_bio_end_io() calls the original endio function Which is end_bbio_data_read(), and it calls bio_put() for the original bio.
Now the original bio is freed.
- The submitted first 64K bio finished Now we call into btrfs_check_read_bio() and tries to advance the bio iter. But since the original bio (thus its iter) is already freed, we trigger the above use-after free.
And even if the memory is not poisoned/corrupted, we will later call the original endio function, causing a double freeing.
[FIX] Instead of calling btrfs_bio_end_io(), call btrfs_orig_bbio_end_io(), which has the extra check on split bios and do the pr ---truncated---(CVE-2024-46687)
In the Linux kernel, the following vulnerability has been resolved:
tty: serial: fsl_lpuart: mark last busy before uart_add_one_port
With "earlycon initcall_debug=1 loglevel=8" in bootargs, kernel sometimes boot hang. It is because normal console still is not ready, but runtime suspend is called, so early console putchar will hang in waiting TRDE set in UARTSTAT.
The lpuart driver has auto suspend delay set to 3000ms, but during uart_add_one_port, a child device serial ctrl will added and probed with its pm runtime enabled(see serial_ctrl.c). The runtime suspend call path is: device_add |-> bus_probe_device |->device_initial_probe |->__device_attach |-> pm_runtime_get_sync(dev->parent); |-> pm_request_idle(dev); |-> pm_runtime_put(dev->parent);
So in the end, before normal console ready, the lpuart get runtime suspended. And earlycon putchar will hang.
To address the issue, mark last busy just after pm_runtime_enable, three seconds is long enough to switch from bootconsole to normal console.(CVE-2024-46706)

btrfs: fix qgroup reserve leaks in cow_file_range
In the buffered write path, the dirty page owns the qgroup reserve until it creates an ordered_extent.
Therefore, any errors that occur before the ordered_extent is created must free that reservation, or else the space is leaked. The fstest generic/475 exercises various IO error paths, and is able to trigger errors in cow_file_range where we fail to get to allocating the ordered extent. Note that because we do clear delalloc, we are likely to remove the inode from the delalloc list, so the inodes/pages to not have invalidate/launder called on them in the commit abort path.
This results in failures at the unmount stage of the test that look like:

Squashfs: sanity check symbolic link size
Syzkiller reports a "KMSAN: uninit-value in pick_link" bug.
This is caused by an uninitialised page, which is ultimately caused by a corrupted symbolic link size read from disk.
The reason why the corrupted symlink size causes an uninitialised page is due to the following sequence of events:
-
squashfs_read_inode() is called to read the symbolic link from disk. This assigns the corrupted value 3875536935 to inode->i_size.
-
Later squashfs_symlink_read_folio() is called, which assigns this corrupted value to the length variable, which being a signed int, overflows producing a negative number.
-
The following loop that fills in the page contents checks that the copied bytes is less than length, which being negative means the loop is skipped, producing an uninitialised page.
This patch adds a sanity check which checks that the symbolic link size is not larger than expected.

Additionally, such request may put undue burden on the system which will try to free a lot of memory for a bogus request.

DIV_ROUND_CLOSEST() after kstrtol() results in an underflow if a large negative number such as -9223372036854775808 is provided by the user. Fix it by reordering clamp_val() and DIV_ROUND_CLOSEST() operations.(CVE-2024-46759)
In the Linux kernel, the following vulnerability has been resolved:
eventfs: Use list_del_rcu() for SRCU protected list variable
Chi Zhiling reported:
We found a null pointer accessing in tracefs[1], the reason is that the variable 'ei_child' is set to LIST_POISON1, that means the list was removed in eventfs_remove_rec. so when access the ei_child->is_freed, the panic triggered.
by the way, the following script can reproduce this panic
loop1 (){ while true do echo "p:kp submit_bio" > /sys/kernel/debug/tracing/kprobe_events echo "" > /sys/kernel/debug/tracing/kprobe_events done } loop2 (){ while true do tree /sys/kernel/debug/tracing/events/kprobes/ done } loop1 & loop2

In the Linux kernel, the following vulnerability has been resolved:
fscache: delete fscache_cookie_lru_timer when fscache exits to avoid UAF
The fscache_cookie_lru_timer is initialized when the fscache module is inserted, but is not deleted when the fscache module is removed. If timer_reduce() is called before removing the fscache module, the fscache_cookie_lru_timer will be added to the timer list of the current cpu. Afterwards, a use-after-free will be triggered in the softIRQ after removing the fscache module, as follows:

In the Linux kernel, the following vulnerability has been resolved:
sch/netem: fix use after free in netem_dequeue
If netem_dequeue() enqueues packet to inner qdisc and that qdisc returns __NET_XMIT_STOLEN. The packet is dropped but qdisc_tree_reduce_backlog() is not called to update the parent's q.qlen, leading to the similar use-after-free as Commit e04991a48dbaf382 ("netem: fix return value if duplicate enqueue fails")

This patch adds it back but at a later point (when calling\nmlx5e_safe_reopen_channels()) to avoid the deadlock referenced in the\nFixes tag.(CVE-2024-45019)\r\n\r\nIn the Linux kernel, the following vulnerability has been resolved:\r\n\r\nfix bitmap corruption on close_range() with CLOSE_RANGE_UNSHARE\r\n\r\ncopy_fd_bitmaps(new, old, count) is expected to copy the first\ncount/BITS_PER_LONG bits from old-\u0026gt;full_fds_bits[] and fill\nthe rest with zeroes. What it does is copying enough words\n(BITS_TO_LONGS(count/BITS_PER_LONG)), then memsets the rest.\nThat works fine, *if* all bits past the cutoff point are\nclear. Otherwise we are risking garbage from the last word\nwe\u0026apos;d copied.\r\n\r\nFor most of the callers that is true - expand_fdtable() has\ncount equal to old-\u0026gt;max_fds, so there\u0026apos;s no open descriptors\npast count, let alone fully occupied words in -\u0026gt;open_fds[],\nwhich is what bits in -\u0026gt;full_fds_bits[] correspond to.\r\n\r\nThe other caller (dup_fd()) passes sane_fdtable_size(old_fdt, max_fds),\nwhich is the smallest multiple of BITS_PER_LONG that covers all\nopened descriptors below max_fds. In the common case (copying on\nfork()) max_fds is ~0U, so all opened descriptors will be below\nit and we are fine, by the same reasons why the call in expand_fdtable()\nis safe.\r\n\r\nUnfortunately, there is a case where max_fds is less than that\nand where we might, indeed, end up with junk in -\u0026gt;full_fds_bits[] -\nclose_range(from, to, CLOSE_RANGE_UNSHARE) with\n\t* descriptor table being currently shared\n\t* \u0026apos;to\u0026apos; being above the current capacity of descriptor table\n\t* \u0026apos;from\u0026apos; being just under some chunk of opened descriptors.\nIn that case we end up with observably wrong behaviour - e.g. spawn\na child with CLONE_FILES, get all descriptors in range 0..127 open,\nthen close_range(64, ~0U, CLOSE_RANGE_UNSHARE) and watch dup(0) ending\nup with descriptor #128, despite #64 being observably not open.\r\n\r\nThe minimally invasive fix would be to deal with that in dup_fd().\nIf this proves to add measurable overhead, we can go that way, but\nlet\u0026apos;s try to fix copy_fd_bitmaps() first.\r\n\r\n* new helper: bitmap_copy_and_expand(to, from, bits_to_copy, size).\n* make copy_fd_bitmaps() take the bitmap size in words, rather than\nbits; it\u0026apos;s \u0026apos;count\u0026apos; argument is always a multiple of BITS_PER_LONG,\nso we are not losing any information, and that way we can use the\nsame helper for all three bitmaps - compiler will see that count\nis a multiple of BITS_PER_LONG for the large ones, so it\u0026apos;ll generate\nplain memcpy()+memset().\r\n\r\nReproducer added to tools/testing/selftests/core/close_range_test.c(CVE-2024-45025)\r\n\r\nIn the Linux kernel, the following vulnerability has been resolved:\r\n\r\nbtrfs: fix a use-after-free when hitting errors inside btrfs_submit_chunk()\r\n\r\n[BUG]\nThere is an internal report that KASAN is reporting use-after-free, with\nthe following backtrace:\r\n\r\n BUG: KASAN: slab-use-after-free in btrfs_check_read_bio+0xa68/0xb70 [btrfs]\n Read of size 4 at addr ffff8881117cec28 by task kworker/u16:2/45\n CPU: 1 UID: 0 PID: 45 Comm: kworker/u16:2 Not tainted 6.11.0-rc2-next-20240805-default+ #76\n Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS rel-1.16.2-3-gd478f380-rebuilt.opensuse.org 04/01/2014\n Workqueue: btrfs-endio btrfs_end_bio_work [btrfs]\n Call Trace:\n dump_stack_lvl+0x61/0x80\n print_address_description.constprop.0+0x5e/0x2f0\n print_report+0x118/0x216\n kasan_report+0x11d/0x1f0\n btrfs_check_read_bio+0xa68/0xb70 [btrfs]\n process_one_work+0xce0/0x12a0\n worker_thread+0x717/0x1250\n kthread+0x2e3/0x3c0\n ret_from_fork+0x2d/0x70\n ret_from_fork_asm+0x11/0x20\r\n\r\n Allocated by task 20917:\n kasan_save_stack+0x37/0x60\n kasan_save_track+0x10/0x30\n __kasan_slab_alloc+0x7d/0x80\n kmem_cache_alloc_noprof+0x16e/0x3e0\n mempool_alloc_noprof+0x12e/0x310\n bio_alloc_bioset+0x3f0/0x7a0\n btrfs_bio_alloc+0x2e/0x50 [btrfs]\n submit_extent_page+0x4d1/0xdb0 [btrfs]\n btrfs_do_readpage+0x8b4/0x12a0 [btrfs]\n btrfs_readahead+0x29a/0x430 [btrfs]\n read_pages+0x1a7/0xc60\n page_cache_ra_unbounded+0x2ad/0x560\n filemap_get_pages+0x629/0xa20\n filemap_read+0x335/0xbf0\n vfs_read+0x790/0xcb0\n ksys_read+0xfd/0x1d0\n do_syscall_64+0x6d/0x140\n entry_SYSCALL_64_after_hwframe+0x4b/0x53\r\n\r\n Freed by task 20917:\n kasan_save_stack+0x37/0x60\n kasan_save_track+0x10/0x30\n kasan_save_free_info+0x37/0x50\n __kasan_slab_free+0x4b/0x60\n kmem_cache_free+0x214/0x5d0\n bio_free+0xed/0x180\n end_bbio_data_read+0x1cc/0x580 [btrfs]\n btrfs_submit_chunk+0x98d/0x1880 [btrfs]\n btrfs_submit_bio+0x33/0x70 [btrfs]\n submit_one_bio+0xd4/0x130 [btrfs]\n submit_extent_page+0x3ea/0xdb0 [btrfs]\n btrfs_do_readpage+0x8b4/0x12a0 [btrfs]\n btrfs_readahead+0x29a/0x430 [btrfs]\n read_pages+0x1a7/0xc60\n page_cache_ra_unbounded+0x2ad/0x560\n filemap_get_pages+0x629/0xa20\n filemap_read+0x335/0xbf0\n vfs_read+0x790/0xcb0\n ksys_read+0xfd/0x1d0\n do_syscall_64+0x6d/0x140\n entry_SYSCALL_64_after_hwframe+0x4b/0x53\r\n\r\n[CAUSE]\nAlthough I cannot reproduce the error, the report itself is good enough\nto pin down the cause.\r\n\r\nThe call trace is the regular endio workqueue context, but the\nfree-by-task trace is showing that during btrfs_submit_chunk() we\nalready hit a critical error, and is calling btrfs_bio_end_io() to error\nout.

Vulnerability from osv_openeuler
The Linux Kernel, the operating system core itself.
Security Fix(es):
In the Linux kernel, the following vulnerability has been resolved:
clk: sunxi-ng: Unregister clocks/resets when unbinding
Currently, unbinding a CCU driver unmaps the device's MMIO region, while leaving its clocks/resets and their providers registered. This can cause a page fault later when some clock operation tries to perform MMIO. Fix this by separating the CCU initialization from the memory allocation, and then using a devres callback to unregister the clocks and resets.
This also fixes a memory leak of the struct ccu_reset, and uses the
correct owner (the specific platform driver) for the clocks and resets.
Early OF clock providers are never unregistered, and limited error handling is possible, so they are mostly unchanged. The error reporting is made more consistent by moving the message inside of_sunxi_ccu_probe.(CVE-2021-47205)
In the Linux kernel, the following vulnerability has been resolved:
NFSD: Fix ia_size underflow
iattr::ia_size is a loff_t, which is a signed 64-bit type. NFSv3 and NFSv4 both define file size as an unsigned 64-bit type. Thus there is a range of valid file size values an NFS client can send that is already larger than Linux can handle.
Currently decode_fattr4() dumps a full u64 value into ia_size. If that value happens to be larger than S64_MAX, then ia_size underflows. I'm about to fix up the NFSv3 behavior as well, so let's catch the underflow in the common code path: nfsd_setattr().(CVE-2022-48828)
In the Linux kernel, the following vulnerability has been resolved:
net: mvpp2: clear BM pool before initialization
Register value persist after booting the kernel using kexec which results in kernel panic. Thus clear the BM pool registers before initialisation to fix the issue.(CVE-2024-35837)
In the Linux kernel, the following vulnerability has been resolved:
drivers: core: synchronize really_probe() and dev_uevent()
Synchronize the dev->driver usage in really_probe() and dev_uevent(). These can run in different threads, what can result in the following race condition for dev->driver uninitialization:
Thread #1:
really_probe() { ... probe_failed: ... device_unbind_cleanup(dev) { ... dev->driver = NULL; // <= Failed probe sets dev->driver to NULL ... } ... }
Thread #2:
dev_uevent() { ... if (dev->driver) // If dev->driver is NULLed from really_probe() from here on, // after above check, the system crashes add_uevent_var(env, "DRIVER=%s", dev->driver->name); ... }
really_probe() holds the lock, already. So nothing needs to be done there. dev_uevent() is called with lock held, often, too. But not always. What implies that we can't add any locking in dev_uevent() itself. So fix this race by adding the lock to the non-protected path. This is the path where above race is observed:
dev_uevent+0x235/0x380 uevent_show+0x10c/0x1f0 <= Add lock here dev_attr_show+0x3a/0xa0 sysfs_kf_seq_show+0x17c/0x250 kernfs_seq_show+0x7c/0x90 seq_read_iter+0x2d7/0x940 kernfs_fop_read_iter+0xc6/0x310 vfs_read+0x5bc/0x6b0 ksys_read+0xeb/0x1b0 __x64_sys_read+0x42/0x50 x64_sys_call+0x27ad/0x2d30 do_syscall_64+0xcd/0x1d0 entry_SYSCALL_64_after_hwframe+0x77/0x7f
Similar cases are reported by syzkaller in
https://syzkaller.appspot.com/bug?extid=ffa8143439596313a85a
But these are regarding the initialization of dev->driver
dev->driver = drv;
As this switches dev->driver to non-NULL these reports can be considered to be false-positives (which should be "fixed" by this commit, as well, though).
The same issue was reported and tried to be fixed back in 2015 in

In the Linux kernel, the following vulnerability has been resolved:
scsi: qedi: Fix crash while reading debugfs attribute
The qedi_dbg_do_not_recover_cmd_read() function invokes sprintf() directly on a __user pointer, which results into the crash.
To fix this issue, use a small local stack buffer for sprintf() and then call simple_read_from_buffer(), which in turns make the copy_to_user() call.

In the Linux kernel, the following vulnerability has been resolved:
nilfs2: add missing check for inode numbers on directory entries
Syzbot reported that mounting and unmounting a specific pattern of corrupted nilfs2 filesystem images causes a use-after-free of metadata file inodes, which triggers a kernel bug in lru_add_fn().
As Jan Kara pointed out, this is because the link count of a metadata file gets corrupted to 0, and nilfs_evict_inode(), which is called from iput(), tries to delete that inode (ifile inode in this case).
The inconsistency occurs because directories containing the inode numbers of these metadata files that should not be visible in the namespace are read without checking.
Fix this issue by treating the inode numbers of these internal files as errors in the sanity check helper when reading directory folios/pages.

lib: objagg: Fix general protection fault
The library supports aggregation of objects into other objects only if the parent object does not have a parent itself. That is, nesting is not supported.
Aggregation happens in two cases: Without and with hints, where hints are a pre-computed recommendation on how to aggregate the provided objects.
Nesting is not possible in the first case due to a check that prevents it, but in the second case there is no check because the assumption is that nesting cannot happen when creating objects based on hints. The violation of this assumption leads to various warnings and eventually to a general protection fault [1].
Before fixing the root cause, error out when nesting happens and warn.

drm/vmwgfx: Fix a deadlock in dma buf fence polling
Introduce a version of the fence ops that on release doesn't remove the fence from the pending list, and thus doesn't require a lock to fix poll->fence wait->fence unref deadlocks.
vmwgfx overwrites the wait callback to iterate over the list of all fences and update their status, to do that it holds a lock to prevent the list modifcations from other threads. The fence destroy callback both deletes the fence and removes it from the list of pending fences, for which it holds a lock.
dma buf polling cb unrefs a fence after it's been signaled: so the poll calls the wait, which signals the fences, which are being destroyed. The destruction tries to acquire the lock on the pending fences list which it can never get because it's held by the wait from which it was called.
Old bug, but not a lot of userspace apps were using dma-buf polling interfaces. Fix those, in particular this fixes KDE stalls/deadlock.(CVE-2024-43863)

x86/mm: Fix pti_clone_pgtable() alignment assumption
Guenter reported dodgy crashes on an i386-nosmp build using GCC-11 that had the form of endless traps until entry stack exhaust and then
DF from the stack guard.
It turned out that pti_clone_pgtable() had alignment assumptions on the start address, notably it hard assumes start is PMD aligned. This is true on x86_64, but very much not true on i386.
These assumptions can cause the end condition to malfunction, leading to a 'short' clone. Guess what happens when the user mapping has a short copy of the entry text?
Use the correct increment form for addr to avoid alignment assumptions.(CVE-2024-44965)

In the Linux kernel, the following vulnerability has been resolved:
vfs: Don't evict inode under the inode lru traversing context
The inode reclaiming process(See function prune_icache_sb) collects all reclaimable inodes and mark them with I_FREEING flag at first, at that time, other processes will be stuck if they try getting these inodes (See function find_inode_fast), then the reclaiming process destroy the inodes by function dispose_list(). Some filesystems(eg. ext4 with ea_inode feature, ubifs with xattr) may do inode lookup in the inode evicting callback function, if the inode lookup is operated under the inode lru traversing context, deadlock problems may happen.
Case 1: In function ext4_evict_inode(), the ea inode lookup could happen if ea_inode feature is enabled, the lookup process will be stuck under the evicting context like this:
- File A has inode i_reg and an ea inode i_ea
- getfattr(A, xattr_buf) // i_ea is added into lru // lru->i_ea
-
Then, following three processes running like this:
PA PB echo 2 > /proc/sys/vm/drop_caches shrink_slab prune_dcache_sb // i_reg is added into lru, lru->i_ea->i_reg prune_icache_sb list_lru_walk_one inode_lru_isolate i_ea->i_state |= I_FREEING // set inode state inode_lru_isolate __iget(i_reg) spin_unlock(&i_reg->i_lock) spin_unlock(lru_lock) rm file A i_reg->nlink = 0 iput(i_reg) // i_reg->nlink is 0, do evict ext4_evict_inode ext4_xattr_delete_inode ext4_xattr_inode_dec_ref_all ext4_xattr_inode_iget ext4_iget(i_ea->i_ino) iget_locked find_inode_fast __wait_on_freeing_inode(i_ea) ----→ AA deadlock dispose_list // cannot be executed by prune_icache_sb wake_up_bit(&i_ea->i_state)
Case 2: In deleted inode writing function ubifs_jnl_write_inode(), file deleting process holds BASEHD's wbuf->io_mutex while getting the xattr inode, which could race with inode reclaiming process(The reclaiming process could try locking BASEHD's wbuf->io_mutex in inode evicting function), then an ABBA deadlock problem would happen as following:
- File A has inode ia and a xattr(with inode ixa), regular file B has inode ib and a xattr.
- getfattr(A, xattr_buf) // ixa is added into lru // lru->ixa

In the Linux kernel, the following vulnerability has been resolved:
fix bitmap corruption on close_range() with CLOSE_RANGE_UNSHARE
copy_fd_bitmaps(new, old, count) is expected to copy the first count/BITS_PER_LONG bits from old->full_fds_bits[] and fill the rest with zeroes. What it does is copying enough words (BITS_TO_LONGS(count/BITS_PER_LONG)), then memsets the rest. That works fine, if all bits past the cutoff point are clear. Otherwise we are risking garbage from the last word we'd copied.
For most of the callers that is true - expand_fdtable() has count equal to old->max_fds, so there's no open descriptors past count, let alone fully occupied words in ->open_fds[], which is what bits in ->full_fds_bits[] correspond to.
The other caller (dup_fd()) passes sane_fdtable_size(old_fdt, max_fds), which is the smallest multiple of BITS_PER_LONG that covers all opened descriptors below max_fds. In the common case (copying on fork()) max_fds is ~0U, so all opened descriptors will be below it and we are fine, by the same reasons why the call in expand_fdtable() is safe.
Unfortunately, there is a case where max_fds is less than that and where we might, indeed, end up with junk in ->full_fds_bits[] - close_range(from, to, CLOSE_RANGE_UNSHARE) with * descriptor table being currently shared * 'to' being above the current capacity of descriptor table * 'from' being just under some chunk of opened descriptors. In that case we end up with observably wrong behaviour - e.g. spawn a child with CLONE_FILES, get all descriptors in range 0..127 open, then close_range(64, ~0U, CLOSE_RANGE_UNSHARE) and watch dup(0) ending up with descriptor #128, despite #64 being observably not open.
The minimally invasive fix would be to deal with that in dup_fd(). If this proves to add measurable overhead, we can go that way, but let's try to fix copy_fd_bitmaps() first.
- new helper: bitmap_copy_and_expand(to, from, bits_to_copy, size).
- make copy_fd_bitmaps() take the bitmap size in words, rather than bits; it's 'count' argument is always a multiple of BITS_PER_LONG, so we are not losing any information, and that way we can use the same helper for all three bitmaps - compiler will see that count is a multiple of BITS_PER_LONG for the large ones, so it'll generate plain memcpy()+memset().

In the Linux kernel, the following vulnerability has been resolved:
btrfs: fix qgroup reserve leaks in cow_file_range
In the buffered write path, the dirty page owns the qgroup reserve until it creates an ordered_extent.
Therefore, any errors that occur before the ordered_extent is created must free that reservation, or else the space is leaked. The fstest generic/475 exercises various IO error paths, and is able to trigger errors in cow_file_range where we fail to get to allocating the ordered extent. Note that because we do clear delalloc, we are likely to remove the inode from the delalloc list, so the inodes/pages to not have invalidate/launder called on them in the commit abort path.
This results in failures at the unmount stage of the test that look like:

In the Linux kernel, the following vulnerability has been resolved:
smb/server: fix potential null-ptr-deref of lease_ctx_info in smb2_open()
null-ptr-deref will occur when (req_op_level == SMB2_OPLOCK_LEVEL_LEASE) and parse_lease_state() return NULL.

In the Linux kernel, the following vulnerability has been resolved:
Squashfs: sanity check symbolic link size
Syzkiller reports a "KMSAN: uninit-value in pick_link" bug.
This is caused by an uninitialised page, which is ultimately caused by a corrupted symbolic link size read from disk.
The reason why the corrupted symlink size causes an uninitialised page is due to the following sequence of events:
-
squashfs_read_inode() is called to read the symbolic link from disk. This assigns the corrupted value 3875536935 to inode->i_size.
-
Later squashfs_symlink_read_folio() is called, which assigns this corrupted value to the length variable, which being a signed int, overflows producing a negative number.
-
The following loop that fills in the page contents checks that the copied bytes is less than length, which being negative means the loop is skipped, producing an uninitialised page.
This patch adds a sanity check which checks that the symbolic link size is not larger than expected.

V2: fix spelling mistake.(CVE-2024-46744)
In the Linux kernel, the following vulnerability has been resolved:
Input: uinput - reject requests with unreasonable number of slots
When exercising uinput interface syzkaller may try setting up device with a really large number of slots, which causes memory allocation failure in input_mt_init_slots(). While this allocation failure is handled properly and request is rejected, it results in syzkaller reports. Additionally, such request may put undue burden on the system which will try to free a lot of memory for a bogus request.
Fix it by limiting allowed number of slots to 100. This can easily be extended if we see devices that can track more than 100 contacts.(CVE-2024-46745)

Instead of a BUG_ON() just return an error, log an error message and abort the transaction in case we find an extent buffer belonging to the relocation tree that doesn't have the full backref flag set. This is unexpected and should never happen (save for bugs or a potential bad memory).(CVE-2024-46752)
In the Linux kernel, the following vulnerability has been resolved:
userfaultfd: fix checks for huge PMDs
Patch series "userfaultfd: fix races around pmd_trans_huge() check", v2.
The pmd_trans_huge() code in mfill_atomic() is wrong in three different ways depending on kernel version:
- The pmd_trans_huge() check is racy and can lead to a BUG_ON() (if you hit the right two race windows) - I've tested this in a kernel build with some extra mdelay() calls. See the commit message for a description of the race scenario. On older kernels (before 6.5), I think the same bug can even theoretically lead to accessing transhuge page contents as a page table if you hit the right 5 narrow race windows (I haven't tested this case).
- As pointed out by Qi Zheng, pmd_trans_huge() is not sufficient for detecting PMDs that don't point to page tables. On older kernels (before 6.5), you'd just have to win a single fairly wide race to hit this. I've tested this on 6.1 stable by racing migration (with a mdelay() patched into try_to_migrate()) against UFFDIO_ZEROPAGE - on my x86 VM, that causes a kernel oops in ptlock_ptr().
- On newer kernels (>=6.5), for shmem mappings, khugepaged is allowed to yank page tables out from under us (though I haven't tested that), so I think the BUG_ON() checks in mfill_atomic() are just wrong.
I decided to write two separate fixes for these (one fix for bugs 1+2, one fix for bug 3), so that the first fix can be backported to kernels affected by bugs 1+2.
This patch (of 2):
This fixes two issues.
I discovered that the following race can occur:
mfill_atomic other thread ============ ============ <zap PMD> pmdp_get_lockless() [reads none pmd] <bail if trans_huge> <if none:> <pagefault creates transhuge zeropage> __pte_alloc [no-op] <zap PMD> <bail if pmd_trans_huge(dst_pmd)> BUG_ON(pmd_none(dst_pmd))
I have experimentally verified this in a kernel with extra mdelay() calls; the BUG_ON(pmd_none(*dst_pmd)) triggers.
On kernels newer than commit 0d940a9b270b ("mm/pgtable: allow pte_offset_map_lock to fail"), this can't lead to anything worse than a BUG_ON(), since the page table access helpers are actually designed to deal with page tables concurrently disappearing; but on older kernels (<=6.4), I think we could probably theoretically race past the two BUG_ON() checks and end up treating a hugepage as a page table.
The second issue is that, as Qi Zheng pointed out, there are other types of huge PMDs that pmd_trans_huge() can't catch: devmap PMDs and swap PMDs (in particular, migration PMDs).
On <=6.4, this is worse than the first issue: If mfill_atomic() runs on a PMD that contains a migration entry (which just requires winning a single, fairly wide race), it will pass the PMD to pte_offset_map_lock(), which assumes that the PMD points to a page table.
Breakage follows: First, the kernel tries to take the PTE lock (which will crash or maybe worse if there is no "struct page" for the address bits in the migration entry PMD - I think at least on X86 there usually is no corresponding "struct page" thanks to the PTE inversion mitigation, amd64 looks different).
If that didn't crash, the kernel would next try to write a PTE into what it wrongly thinks is a page table.
As part of fixing these issues, get rid of the check for pmd_trans_huge() before __pte_alloc() - that's redundant, we're going to have to check for that after the __pte_alloc() anyway.
Backport note: pmdp_get_lockless() is pmd_read_atomic() in older kernels.(CVE-2024-46787)

What it does is copying enough words\n(BITS_TO_LONGS(count/BITS_PER_LONG)), then memsets the rest.\nThat works fine, *if* all bits past the cutoff point are\nclear. Otherwise we are risking garbage from the last word\nwe\u0026apos;d copied.\r\n\r\nFor most of the callers that is true - expand_fdtable() has\ncount equal to old-\u0026gt;max_fds, so there\u0026apos;s no open descriptors\npast count, let alone fully occupied words in -\u0026gt;open_fds[],\nwhich is what bits in -\u0026gt;full_fds_bits[] correspond to.\r\n\r\nThe other caller (dup_fd()) passes sane_fdtable_size(old_fdt, max_fds),\nwhich is the smallest multiple of BITS_PER_LONG that covers all\nopened descriptors below max_fds. In the common case (copying on\nfork()) max_fds is ~0U, so all opened descriptors will be below\nit and we are fine, by the same reasons why the call in expand_fdtable()\nis safe.\r\n\r\nUnfortunately, there is a case where max_fds is less than that\nand where we might, indeed, end up with junk in -\u0026gt;full_fds_bits[] -\nclose_range(from, to, CLOSE_RANGE_UNSHARE) with\n\t* descriptor table being currently shared\n\t* \u0026apos;to\u0026apos; being above the current capacity of descriptor table\n\t* \u0026apos;from\u0026apos; being just under some chunk of opened descriptors.\nIn that case we end up with observably wrong behaviour - e.g. spawn\na child with CLONE_FILES, get all descriptors in range 0..127 open,\nthen close_range(64, ~0U, CLOSE_RANGE_UNSHARE) and watch dup(0) ending\nup with descriptor #128, despite #64 being observably not open.\r\n\r\nThe minimally invasive fix would be to deal with that in dup_fd().\nIf this proves to add measurable overhead, we can go that way, but\nlet\u0026apos;s try to fix copy_fd_bitmaps() first.\r\n\r\n* new helper: bitmap_copy_and_expand(to, from, bits_to_copy, size).\n* make copy_fd_bitmaps() take the bitmap size in words, rather than\nbits; it\u0026apos;s \u0026apos;count\u0026apos; argument is always a multiple of BITS_PER_LONG,\nso we are not losing any information, and that way we can use the\nsame helper for all three bitmaps - compiler will see that count\nis a multiple of BITS_PER_LONG for the large ones, so it\u0026apos;ll generate\nplain memcpy()+memset().\r\n\r\nReproducer added to tools/testing/selftests/core/close_range_test.c(CVE-2024-45025)\r\n\r\nIn the Linux kernel, the following vulnerability has been resolved:\r\n\r\nmmc: mmc_test: Fix NULL dereference on allocation failure\r\n\r\nIf the \u0026quot;test-\u0026gt;highmem = alloc_pages()\u0026quot; allocation fails then calling\n__free_pages(test-\u0026gt;highmem) will result in a NULL dereference.

On newer kernels (\u0026gt;=6.5), for shmem mappings, khugepaged is allowed\n to yank page tables out from under us (though I haven\u0026apos;t tested that),\n so I think the BUG_ON() checks in mfill_atomic() are just wrong.\r\n\r\nI decided to write two separate fixes for these (one fix for bugs 1+2, one\nfix for bug 3), so that the first fix can be backported to kernels\naffected by bugs 1+2.\r\n\r\n\nThis patch (of 2):\r\n\r\nThis fixes two issues.\r\n\r\nI discovered that the following race can occur:\r\n\r\n mfill_atomic other thread\n ============ ============\n \u0026lt;zap PMD\u0026gt;\n pmdp_get_lockless() [reads none pmd]\n \u0026lt;bail if trans_huge\u0026gt;\n \u0026lt;if none:\u0026gt;\n \u0026lt;pagefault creates transhuge zeropage\u0026gt;\n __pte_alloc [no-op]\n \u0026lt;zap PMD\u0026gt;\n \u0026lt;bail if pmd_trans_huge(*dst_pmd)\u0026gt;\n BUG_ON(pmd_none(*dst_pmd))\r\n\r\nI have experimentally verified this in a kernel with extra mdelay() calls;\nthe BUG_ON(pmd_none(*dst_pmd)) triggers.\r\n\r\nOn kernels newer than commit 0d940a9b270b (\u0026quot;mm/pgtable: allow\npte_offset_map[_lock]() to fail\u0026quot;), this can\u0026apos;t lead to anything worse than\na BUG_ON(), since the page table access helpers are actually designed to\ndeal with page tables concurrently disappearing; but on older kernels\n(\u0026lt;=6.4), I think we could probably theoretically race past the two\nBUG_ON() checks and end up treating a hugepage as a page table.\r\n\r\nThe second issue is that, as Qi Zheng pointed out, there are other types\nof huge PMDs that pmd_trans_huge() can\u0026apos;t catch: devmap PMDs and swap PMDs\n(in particular, migration PMDs).\r\n\r\nOn \u0026lt;=6.4, this is worse than the first issue: If mfill_atomic() runs on a\nPMD that contains a migration entry (which just requires winning a single,\nfairly wide race), it will pass the PMD to pte_offset_map_lock(), which\nassumes that the PMD points to a page table.\r\n\r\nBreakage follows: First, the kernel tries to take the PTE lock (which will\ncrash or maybe worse if there is no \u0026quot;struct page\u0026quot; for the address bits in\nthe migration entry PMD - I think at least on X86 there usually is no\ncorresponding \u0026quot;struct page\u0026quot; thanks to the PTE inversion mitigation, amd64\nlooks different).\r\n\r\nIf that didn\u0026apos;t crash, the kernel would next try to write a PTE into what\nit wrongly thinks is a page table.\r\n\r\nAs part of fixing these issues, get rid of the check for pmd_trans_huge()\nbefore __pte_alloc() - that\u0026apos;s redundant, we\u0026apos;re going to have to check for\nthat after the __pte_alloc() anyway.\r\n\r\nBackport note: pmdp_get_lockless() is pmd_read_atomic() in older kernels.(CVE-2024-46787)\r\n\r\nIn the Linux kernel, the following vulnerability has been resolved:\r\n\r\nsch/netem: fix use after free in netem_dequeue\r\n\r\nIf netem_dequeue() enqueues packet to inner qdisc and that qdisc\nreturns __NET_XMIT_STOLEN.

Vulnerability from osv_openeuler
The Linux Kernel, the operating system core itself.
Security Fix(es):
In the Linux kernel, the following vulnerability has been resolved:
NFSD: Fix ia_size underflow
iattr::ia_size is a loff_t, which is a signed 64-bit type. NFSv3 and NFSv4 both define file size as an unsigned 64-bit type. Thus there is a range of valid file size values an NFS client can send that is already larger than Linux can handle.
Currently decode_fattr4() dumps a full u64 value into ia_size. If that value happens to be larger than S64_MAX, then ia_size underflows. I'm about to fix up the NFSv3 behavior as well, so let's catch the underflow in the common code path: nfsd_setattr().(CVE-2022-48828)
In the Linux kernel, the following vulnerability has been resolved:
drm/amd/pm: fix a double-free in si_dpm_init
When the allocation of adev->pm.dpm.dyn_state.vddc_dependency_on_dispclk.entries fails, amdgpu_free_extended_power_table is called to free some fields of adev. However, when the control flow returns to si_dpm_sw_init, it goes to label dpm_failed and calls si_dpm_fini, which calls amdgpu_free_extended_power_table again and free those fields again. Thus a double-free is triggered.(CVE-2023-52691)
In the Linux kernel, the following vulnerability has been resolved:
netfilter: tproxy: bail out if IP has been disabled on the device
syzbot reports: general protection fault, probably for non-canonical address 0xdffffc0000000003: 0000 [#1] PREEMPT SMP KASAN PTI KASAN: null-ptr-deref in range [0x0000000000000018-0x000000000000001f] [..] RIP: 0010:nf_tproxy_laddr4+0xb7/0x340 net/ipv4/netfilter/nf_tproxy_ipv4.c:62 Call Trace: nft_tproxy_eval_v4 net/netfilter/nft_tproxy.c:56 [inline] nft_tproxy_eval+0xa9a/0x1a00 net/netfilter/nft_tproxy.c:168
__in_dev_get_rcu() can return NULL, so check for this.(CVE-2024-36270)
In the Linux kernel, the following vulnerability has been resolved:
nfc: llcp: fix nfc_llcp_setsockopt() unsafe copies
syzbot reported unsafe calls to copy_from_sockptr() [1]
Use copy_safe_from_sockptr() instead.

In the Linux kernel, the following vulnerability has been resolved:
drivers: core: synchronize really_probe() and dev_uevent()
Synchronize the dev->driver usage in really_probe() and dev_uevent(). These can run in different threads, what can result in the following race condition for dev->driver uninitialization:
Thread #1:
really_probe() { ... probe_failed: ... device_unbind_cleanup(dev) { ... dev->driver = NULL; // <= Failed probe sets dev->driver to NULL ... } ... }
Thread #2:
dev_uevent() { ... if (dev->driver) // If dev->driver is NULLed from really_probe() from here on, // after above check, the system crashes add_uevent_var(env, "DRIVER=%s", dev->driver->name); ... }
really_probe() holds the lock, already. So nothing needs to be done there. dev_uevent() is called with lock held, often, too. But not always. What implies that we can't add any locking in dev_uevent() itself. So fix this race by adding the lock to the non-protected path. This is the path where above race is observed:
dev_uevent+0x235/0x380 uevent_show+0x10c/0x1f0 <= Add lock here dev_attr_show+0x3a/0xa0 sysfs_kf_seq_show+0x17c/0x250 kernfs_seq_show+0x7c/0x90 seq_read_iter+0x2d7/0x940 kernfs_fop_read_iter+0xc6/0x310 vfs_read+0x5bc/0x6b0 ksys_read+0xeb/0x1b0 __x64_sys_read+0x42/0x50 x64_sys_call+0x27ad/0x2d30 do_syscall_64+0xcd/0x1d0 entry_SYSCALL_64_after_hwframe+0x77/0x7f
Similar cases are reported by syzkaller in
https://syzkaller.appspot.com/bug?extid=ffa8143439596313a85a
But these are regarding the initialization of dev->driver
dev->driver = drv;
As this switches dev->driver to non-NULL these reports can be considered to be false-positives (which should be "fixed" by this commit, as well, though).
The same issue was reported and tried to be fixed back in 2015 in
https://lore.kernel.org/lkml/1421259054-2574-1-git-send-email-a.sangwan@samsung.com/
already.(CVE-2024-39501)
In the Linux kernel, the following vulnerability has been resolved:
scsi: qedi: Fix crash while reading debugfs attribute
The qedi_dbg_do_not_recover_cmd_read() function invokes sprintf() directly on a __user pointer, which results into the crash.
To fix this issue, use a small local stack buffer for sprintf() and then call simple_read_from_buffer(), which in turns make the copy_to_user() call.

If the ata_port_alloc() call in ata_host_alloc() fails, ata_host_release() will get called.
However, the code in ata_host_release() tries to free ata_port struct members unconditionally, which can lead to the following:

In the Linux kernel, the following vulnerability has been resolved:
nilfs2: add missing check for inode numbers on directory entries
Syzbot reported that mounting and unmounting a specific pattern of corrupted nilfs2 filesystem images causes a use-after-free of metadata file inodes, which triggers a kernel bug in lru_add_fn().
As Jan Kara pointed out, this is because the link count of a metadata file gets corrupted to 0, and nilfs_evict_inode(), which is called from iput(), tries to delete that inode (ifile inode in this case).
The inconsistency occurs because directories containing the inode numbers of these metadata files that should not be visible in the namespace are read without checking.
Fix this issue by treating the inode numbers of these internal files as errors in the sanity check helper when reading directory folios/pages.

lib: objagg: Fix general protection fault
The library supports aggregation of objects into other objects only if the parent object does not have a parent itself. That is, nesting is not supported.
Aggregation happens in two cases: Without and with hints, where hints are a pre-computed recommendation on how to aggregate the provided objects.
Nesting is not possible in the first case due to a check that prevents it, but in the second case there is no check because the assumption is that nesting cannot happen when creating objects based on hints. The violation of this assumption leads to various warnings and eventually to a general protection fault [1].
Before fixing the root cause, error out when nesting happens and warn.

drm/vmwgfx: Fix a deadlock in dma buf fence polling
Introduce a version of the fence ops that on release doesn't remove the fence from the pending list, and thus doesn't require a lock to fix poll->fence wait->fence unref deadlocks.
vmwgfx overwrites the wait callback to iterate over the list of all fences and update their status, to do that it holds a lock to prevent the list modifcations from other threads. The fence destroy callback both deletes the fence and removes it from the list of pending fences, for which it holds a lock.
dma buf polling cb unrefs a fence after it's been signaled: so the poll calls the wait, which signals the fences, which are being destroyed. The destruction tries to acquire the lock on the pending fences list which it can never get because it's held by the wait from which it was called.
Old bug, but not a lot of userspace apps were using dma-buf polling interfaces. Fix those, in particular this fixes KDE stalls/deadlock.(CVE-2024-43863)

x86/mm: Fix pti_clone_pgtable() alignment assumption
Guenter reported dodgy crashes on an i386-nosmp build using GCC-11 that had the form of endless traps until entry stack exhaust and then
DF from the stack guard.
It turned out that pti_clone_pgtable() had alignment assumptions on the start address, notably it hard assumes start is PMD aligned. This is true on x86_64, but very much not true on i386.
These assumptions can cause the end condition to malfunction, leading to a 'short' clone. Guess what happens when the user mapping has a short copy of the entry text?
Use the correct increment form for addr to avoid alignment assumptions.(CVE-2024-44965)

In the Linux kernel, the following vulnerability has been resolved:
vfs: Don't evict inode under the inode lru traversing context
The inode reclaiming process(See function prune_icache_sb) collects all reclaimable inodes and mark them with I_FREEING flag at first, at that time, other processes will be stuck if they try getting these inodes (See function find_inode_fast), then the reclaiming process destroy the inodes by function dispose_list(). Some filesystems(eg. ext4 with ea_inode feature, ubifs with xattr) may do inode lookup in the inode evicting callback function, if the inode lookup is operated under the inode lru traversing context, deadlock problems may happen.
Case 1: In function ext4_evict_inode(), the ea inode lookup could happen if ea_inode feature is enabled, the lookup process will be stuck under the evicting context like this:
- File A has inode i_reg and an ea inode i_ea
- getfattr(A, xattr_buf) // i_ea is added into lru // lru->i_ea
-
Then, following three processes running like this:
PA PB echo 2 > /proc/sys/vm/drop_caches shrink_slab prune_dcache_sb // i_reg is added into lru, lru->i_ea->i_reg prune_icache_sb list_lru_walk_one inode_lru_isolate i_ea->i_state |= I_FREEING // set inode state inode_lru_isolate __iget(i_reg) spin_unlock(&i_reg->i_lock) spin_unlock(lru_lock) rm file A i_reg->nlink = 0 iput(i_reg) // i_reg->nlink is 0, do evict ext4_evict_inode ext4_xattr_delete_inode ext4_xattr_inode_dec_ref_all ext4_xattr_inode_iget ext4_iget(i_ea->i_ino) iget_locked find_inode_fast __wait_on_freeing_inode(i_ea) ----→ AA deadlock dispose_list // cannot be executed by prune_icache_sb wake_up_bit(&i_ea->i_state)
Case 2: In deleted inode writing function ubifs_jnl_write_inode(), file deleting process holds BASEHD's wbuf->io_mutex while getting the xattr inode, which could race with inode reclaiming process(The reclaiming process could try locking BASEHD's wbuf->io_mutex in inode evicting function), then an ABBA deadlock problem would happen as following:
- File A has inode ia and a xattr(with inode ixa), regular file B has inode ib and a xattr.
- getfattr(A, xattr_buf) // ixa is added into lru // lru->ixa
- Then, following three processes running like this:
PA PB PC echo 2 > /proc/sys/vm/drop_caches shrink_slab prune_dcache_sb // ib and ia are added into lru, lru->ixa->ib->ia prune_icache_sb list_lru_walk_one inode_lru_isolate ixa->i_state |= I_FREEING // set inode state inode_lru_isolate __iget(ib) spin_unlock(&ib->i_lock) spin_unlock(lru_lock) rm file B ib->nlink = 0rm file A iput(ia) ubifs_evict_inode(ia) ubifs_jnl_delete_inode(ia) ubifs_jnl_write_inode(ia) make_reservation(BASEHD) // Lock wbuf->io_mutex ubifs_iget(ixa->i_ino) iget_locked find_inode_fast __wait_on_freeing_inode(ixa) | iput(ib) // ib->nlink is 0, do evict | ubifs_evict_inode | ubifs_jnl_delete_inode(ib) ↓ ubifs_jnl_write_inode ABBA deadlock ←-----make_reservation(BASEHD) dispose_list // cannot be executed by prune_icache_sb wake_up_bit(&ixa->i_state)

In the Linux kernel, the following vulnerability has been resolved:
fix bitmap corruption on close_range() with CLOSE_RANGE_UNSHARE
copy_fd_bitmaps(new, old, count) is expected to copy the first count/BITS_PER_LONG bits from old->full_fds_bits[] and fill the rest with zeroes. What it does is copying enough words (BITS_TO_LONGS(count/BITS_PER_LONG)), then memsets the rest. That works fine, if all bits past the cutoff point are clear. Otherwise we are risking garbage from the last word we'd copied.
For most of the callers that is true - expand_fdtable() has count equal to old->max_fds, so there's no open descriptors past count, let alone fully occupied words in ->open_fds[], which is what bits in ->full_fds_bits[] correspond to.
The other caller (dup_fd()) passes sane_fdtable_size(old_fdt, max_fds), which is the smallest multiple of BITS_PER_LONG that covers all opened descriptors below max_fds. In the common case (copying on fork()) max_fds is ~0U, so all opened descriptors will be below it and we are fine, by the same reasons why the call in expand_fdtable() is safe.
Unfortunately, there is a case where max_fds is less than that and where we might, indeed, end up with junk in ->full_fds_bits[] - close_range(from, to, CLOSE_RANGE_UNSHARE) with * descriptor table being currently shared * 'to' being above the current capacity of descriptor table * 'from' being just under some chunk of opened descriptors. In that case we end up with observably wrong behaviour - e.g. spawn a child with CLONE_FILES, get all descriptors in range 0..127 open, then close_range(64, ~0U, CLOSE_RANGE_UNSHARE) and watch dup(0) ending up with descriptor #128, despite #64 being observably not open.
The minimally invasive fix would be to deal with that in dup_fd(). If this proves to add measurable overhead, we can go that way, but let's try to fix copy_fd_bitmaps() first.
- new helper: bitmap_copy_and_expand(to, from, bits_to_copy, size).
- make copy_fd_bitmaps() take the bitmap size in words, rather than bits; it's 'count' argument is always a multiple of BITS_PER_LONG, so we are not losing any information, and that way we can use the same helper for all three bitmaps - compiler will see that count is a multiple of BITS_PER_LONG for the large ones, so it'll generate plain memcpy()+memset().

btrfs: fix qgroup reserve leaks in cow_file_range
In the buffered write path, the dirty page owns the qgroup reserve until it creates an ordered_extent.
Therefore, any errors that occur before the ordered_extent is created must free that reservation, or else the space is leaked. The fstest generic/475 exercises various IO error paths, and is able to trigger errors in cow_file_range where we fail to get to allocating the ordered extent. Note that because we do clear delalloc, we are likely to remove the inode from the delalloc list, so the inodes/pages to not have invalidate/launder called on them in the commit abort path.
This results in failures at the unmount stage of the test that look like:

Squashfs: sanity check symbolic link size
Syzkiller reports a "KMSAN: uninit-value in pick_link" bug.
This is caused by an uninitialised page, which is ultimately caused by a corrupted symbolic link size read from disk.
The reason why the corrupted symlink size causes an uninitialised page is due to the following sequence of events:
-
squashfs_read_inode() is called to read the symbolic link from disk. This assigns the corrupted value 3875536935 to inode->i_size.
-
Later squashfs_symlink_read_folio() is called, which assigns this corrupted value to the length variable, which being a signed int, overflows producing a negative number.
-
The following loop that fills in the page contents checks that the copied bytes is less than length, which being negative means the loop is skipped, producing an uninitialised page.
This patch adds a sanity check which checks that the symbolic link size is not larger than expected.

V2: fix spelling mistake.(CVE-2024-46744)
In the Linux kernel, the following vulnerability has been resolved:
Input: uinput - reject requests with unreasonable number of slots
When exercising uinput interface syzkaller may try setting up device with a really large number of slots, which causes memory allocation failure in input_mt_init_slots(). While this allocation failure is handled properly and request is rejected, it results in syzkaller reports. Additionally, such request may put undue burden on the system which will try to free a lot of memory for a bogus request.
Fix it by limiting allowed number of slots to 100. This can easily be extended if we see devices that can track more than 100 contacts.(CVE-2024-46745)
In the Linux kernel, the following vulnerability has been resolved:
HID: cougar: fix slab-out-of-bounds Read in cougar_report_fixup
report_fixup for the Cougar 500k Gaming Keyboard was not verifying that the report descriptor size was correct before accessing it(CVE-2024-46747)
In the Linux kernel, the following vulnerability has been resolved:
btrfs: don't BUG_ON() when 0 reference count at btrfs_lookup_extent_info()
Instead of doing a BUG_ON() handle the error by returning -EUCLEAN, aborting the transaction and logging an error message.(CVE-2024-46751)
In the Linux kernel, the following vulnerability has been resolved:
btrfs: replace BUG_ON() with error handling at update_ref_for_cow()
Instead of a BUG_ON() just return an error, log an error message and abort the transaction in case we find an extent buffer belonging to the relocation tree that doesn't have the full backref flag set. This is unexpected and should never happen (save for bugs or a potential bad memory).(CVE-2024-46752)
In the Linux kernel, the following vulnerability has been resolved:
userfaultfd: fix checks for huge PMDs
Patch series "userfaultfd: fix races around pmd_trans_huge() check", v2.
The pmd_trans_huge() code in mfill_atomic() is wrong in three different ways depending on kernel version:
- The pmd_trans_huge() check is racy and can lead to a BUG_ON() (if you hit the right two race windows) - I've tested this in a kernel build with some extra mdelay() calls. See the commit message for a description of the race scenario. On older kernels (before 6.5), I think the same bug can even theoretically lead to accessing transhuge page contents as a page table if you hit the right 5 narrow race windows (I haven't tested this case).
- As pointed out by Qi Zheng, pmd_trans_huge() is not sufficient for detecting PMDs that don't point to page tables. On older kernels (before 6.5), you'd just have to win a single fairly wide race to hit this. I've tested this on 6.1 stable by racing migration (with a mdelay() patched into try_to_migrate()) against UFFDIO_ZEROPAGE - on my x86 VM, that causes a kernel oops in ptlock_ptr().
- On newer kernels (>=6.5), for shmem mappings, khugepaged is allowed to yank page tables out from under us (though I haven't tested that), so I think the BUG_ON() checks in mfill_atomic() are just wrong.
I decided to write two separate fixes for these (one fix for bugs 1+2, one fix for bug 3), so that the first fix can be backported to kernels affected by bugs 1+2.
This patch (of 2):
This fixes two issues.
I discovered that the following race can occur:
mfill_atomic other thread ============ ============ <zap PMD> pmdp_get_lockless() [reads none pmd] <bail if trans_huge> <if none:> <pagefault creates transhuge zeropage> __pte_alloc [no-op] <zap PMD> <bail if pmd_trans_huge(dst_pmd)> BUG_ON(pmd_none(dst_pmd))
I have experimentally verified this in a kernel with extra mdelay() calls; the BUG_ON(pmd_none(*dst_pmd)) triggers.
On kernels newer than commit 0d940a9b270b ("mm/pgtable: allow pte_offset_map_lock to fail"), this can't lead to anything worse than a BUG_ON(), since the page table access helpers are actually designed to deal with page tables concurrently disappearing; but on older kernels (<=6.4), I think we could probably theoretically race past the two BUG_ON() checks and end up treating a hugepage as a page table.
The second issue is that, as Qi Zheng pointed out, there are other types of huge PMDs that pmd_trans_huge() can't catch: devmap PMDs and swap PMDs (in particular, migration PMDs).
On <=6.4, this is worse than the first issue: If mfill_atomic() runs on a PMD that contains a migration entry (which just requires winning a single, fairly wide race), it will pass the PMD to pte_offset_map_lock(), which assumes that the PMD points to a page table.
Breakage follows: First, the kernel tries to take the PTE lock (which will crash or maybe worse if there is no "struct page" for the address bits in the migration entry PMD - I think at least on X86 there usually is no corresponding "struct page" thanks to the PTE inversion mitigation, amd64 looks different).
If that didn't crash, the kernel would next try to write a PTE into what it wrongly thinks is a page table.
As part of fixing these issues, get rid of the check for pmd_trans_huge() before __pte_alloc() - that's redundant, we're going to have to check for that after the __pte_alloc() anyway.
Backport note: pmdp_get_lockless() is pmd_read_atomic() in older kernels.(CVE-2024-46787)
In the Linux kernel, the following vulnerability has been resolved:
sch/netem: fix use after free in netem_dequeue
If netem_dequeue() enqueues packet to inner qdisc and that qdisc returns __NET_XMIT_STOLEN. The packet is dropped but qdisc_tree_reduce_backlog() is not called to update the parent's q.qlen, leading to the similar use-after-free as Commit e04991a48dbaf382 ("netem: fix return value if duplicate enqueue fails")

In the common case (copying on\nfork()) max_fds is ~0U, so all opened descriptors will be below\nit and we are fine, by the same reasons why the call in expand_fdtable()\nis safe.\r\n\r\nUnfortunately, there is a case where max_fds is less than that\nand where we might, indeed, end up with junk in -\u0026gt;full_fds_bits[] -\nclose_range(from, to, CLOSE_RANGE_UNSHARE) with\n\t* descriptor table being currently shared\n\t* \u0026apos;to\u0026apos; being above the current capacity of descriptor table\n\t* \u0026apos;from\u0026apos; being just under some chunk of opened descriptors.\nIn that case we end up with observably wrong behaviour - e.g. spawn\na child with CLONE_FILES, get all descriptors in range 0..127 open,\nthen close_range(64, ~0U, CLOSE_RANGE_UNSHARE) and watch dup(0) ending\nup with descriptor #128, despite #64 being observably not open.\r\n\r\nThe minimally invasive fix would be to deal with that in dup_fd().\nIf this proves to add measurable overhead, we can go that way, but\nlet\u0026apos;s try to fix copy_fd_bitmaps() first.\r\n\r\n* new helper: bitmap_copy_and_expand(to, from, bits_to_copy, size).\n* make copy_fd_bitmaps() take the bitmap size in words, rather than\nbits; it\u0026apos;s \u0026apos;count\u0026apos; argument is always a multiple of BITS_PER_LONG,\nso we are not losing any information, and that way we can use the\nsame helper for all three bitmaps - compiler will see that count\nis a multiple of BITS_PER_LONG for the large ones, so it\u0026apos;ll generate\nplain memcpy()+memset().\r\n\r\nReproducer added to tools/testing/selftests/core/close_range_test.c(CVE-2024-45025)\r\n\r\nIn the Linux kernel, the following vulnerability has been resolved:\r\n\r\nmmc: mmc_test: Fix NULL dereference on allocation failure\r\n\r\nIf the \u0026quot;test-\u0026gt;highmem = alloc_pages()\u0026quot; allocation fails then calling\n__free_pages(test-\u0026gt;highmem) will result in a NULL dereference. Also\nchange the error code to -ENOMEM instead of returning success.(CVE-2024-45028)\r\n\r\nIn the Linux kernel, the following vulnerability has been resolved:\r\n\r\ndrm/amd/display: Skip wbscl_set_scaler_filter if filter is null\r\n\r\nCallers can pass null in filter (i.e. from returned from the function\nwbscl_get_filter_coeffs_16p) and a null check is added to ensure that is\nnot the case.\r\n\r\nThis fixes 4 NULL_RETURNS issues reported by Coverity.(CVE-2024-46714)\r\n\r\nIn the Linux kernel, the following vulnerability has been resolved:\r\n\r\ndrm/amdgpu: fix ucode out-of-bounds read warning\r\n\r\nClear warning that read ucode[] may out-of-bounds.(CVE-2024-46723)\r\n\r\nIn the Linux kernel, the following vulnerability has been resolved:\r\n\r\ndrm/amd/pm: fix the Out-of-bounds read warning\r\n\r\nusing index i - 1U may beyond element index\nfor mc_data[] when i = 0.(CVE-2024-46731)\r\n\r\nIn the Linux kernel, the following vulnerability has been resolved:\r\n\r\nbtrfs: fix qgroup reserve leaks in cow_file_range\r\n\r\nIn the buffered write path, the dirty page owns the qgroup reserve until\nit creates an ordered_extent.\r\n\r\nTherefore, any errors that occur before the ordered_extent is created\nmust free that reservation, or else the space is leaked. The fstest\ngeneric/475 exercises various IO error paths, and is able to trigger\nerrors in cow_file_range where we fail to get to allocating the ordered\nextent. Note that because we *do* clear delalloc, we are likely to\nremove the inode from the delalloc list, so the inodes/pages to not have\ninvalidate/launder called on them in the commit abort path.\r\n\r\nThis results in failures at the unmount stage of the test that look like:\r\n\r\n BTRFS: error (device dm-8 state EA) in cleanup_transaction:2018: errno=-5 IO failure\n BTRFS: error (device dm-8 state EA) in btrfs_replace_file_extents:2416: errno=-5 IO failure\n BTRFS warning (device dm-8 state EA): qgroup 0/5 has unreleased space, type 0 rsv 28672\n ------------[ cut here ]------------\n WARNING: CPU: 3 PID: 22588 at fs/btrfs/disk-io.c:4333 close_ctree+0x222/0x4d0 [btrfs]\n Modules linked in: btrfs blake2b_generic libcrc32c xor zstd_compress raid6_pq\n CPU: 3 PID: 22588 Comm: umount Kdump: loaded Tainted: G W 6.10.0-rc7-gab56fde445b8 #21\n Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS Arch Linux 1.16.3-1-1 04/01/2014\n RIP: 0010:close_ctree+0x222/0x4d0 [btrfs]\n RSP: 0018:ffffb4465283be00 EFLAGS: 00010202\n RAX: 0000000000000001 RBX: ffffa1a1818e1000 RCX: 0000000000000001\n RDX: 0000000000000000 RSI: ffffb4465283bbe0 RDI: ffffa1a19374fcb8\n RBP: ffffa1a1818e13c0 R08: 0000000100028b16 R09: 0000000000000000\n R10: 0000000000000003 R11: 0000000000000003 R12: ffffa1a18ad7972c\n R13: 0000000000000000 R14: 0000000000000000 R15: 0000000000000000\n FS: 00007f9168312b80(0000) GS:ffffa1a4afcc0000(0000) knlGS:0000000000000000\n CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033\n CR2: 00007f91683c9140 CR3: 000000010acaa000 CR4: 00000000000006f0\n Call Trace:\n \u0026lt;TASK\u0026gt;\n ? close_ctree+0x222/0x4d0 [btrfs]\n ? __warn.cold+0x8e/0xea\n ? close_ctree+0x222/0x4d0 [btrfs]\n ? report_bug+0xff/0x140\n ? handle_bug+0x3b/0x70\n ? exc_invalid_op+0x17/0x70\n ? asm_exc_invalid_op+0x1a/0x20\n ? close_ctree+0x222/0x4d0 [btrfs]\n generic_shutdown_super+0x70/0x160\n kill_anon_super+0x11/0x40\n btrfs_kill_super+0x11/0x20 [btrfs]\n deactivate_locked_super+0x2e/0xa0\n cleanup_mnt+0xb5/0x150\n task_work_run+0x57/0x80\n syscall_exit_to_user_mode+0x121/0x130\n do_syscall_64+0xab/0x1a0\n entry_SYSCALL_64_after_hwframe+0x77/0x7f\n RIP: 0033:0x7f916847a887\n ---[ end trace 0000000000000000 ]---\n BTRFS error (device dm-8 state EA): qgroup reserved space leaked\r\n\r\nCases 2 and 3 in the out_reserve path both pertain to this type of leak\nand must free the reserved qgroup data.

This assigns the corrupted value\n 3875536935 to inode-\u0026gt;i_size.\r\n\r\n2. Later squashfs_symlink_read_folio() is called, which assigns\n this corrupted value to the length variable, which being a\n signed int, overflows producing a negative number.\r\n\r\n3. The following loop that fills in the page contents checks that\n the copied bytes is less than length, which being negative means\n the loop is skipped, producing an uninitialised page.\r\n\r\nThis patch adds a sanity check which checks that the symbolic\nlink size is not larger than expected.\r\n\r\n--\r\n\r\nV2: fix spelling mistake.(CVE-2024-46744)\r\n\r\nIn the Linux kernel, the following vulnerability has been resolved:\r\n\r\nInput: uinput - reject requests with unreasonable number of slots\r\n\r\n\nWhen exercising uinput interface syzkaller may try setting up device\nwith a really large number of slots, which causes memory allocation\nfailure in input_mt_init_slots(). While this allocation failure is\nhandled properly and request is rejected, it results in syzkaller\nreports. Additionally, such request may put undue burden on the\nsystem which will try to free a lot of memory for a bogus request.\r\n\r\nFix it by limiting allowed number of slots to 100. This can easily\nbe extended if we see devices that can track more than 100 contacts.(CVE-2024-46745)\r\n\r\nIn the Linux kernel, the following vulnerability has been resolved:\r\n\r\nHID: cougar: fix slab-out-of-bounds Read in cougar_report_fixup\r\n\r\nreport_fixup for the Cougar 500k Gaming Keyboard was not verifying\nthat the report descriptor size was correct before accessing it(CVE-2024-46747)\r\n\r\nIn the Linux kernel, the following vulnerability has been resolved:\r\n\r\nbtrfs: don\u0026apos;t BUG_ON() when 0 reference count at btrfs_lookup_extent_info()\r\n\r\nInstead of doing a BUG_ON() handle the error by returning -EUCLEAN,\naborting the transaction and logging an error message.(CVE-2024-46751)\r\n\r\nIn the Linux kernel, the following vulnerability has been resolved:\r\n\r\nbtrfs: replace BUG_ON() with error handling at update_ref_for_cow()\r\n\r\nInstead of a BUG_ON() just return an error, log an error message and\nabort the transaction in case we find an extent buffer belonging to the\nrelocation tree that doesn\u0026apos;t have the full backref flag set. This is\nunexpected and should never happen (save for bugs or a potential bad\nmemory).(CVE-2024-46752)\r\n\r\nIn the Linux kernel, the following vulnerability has been resolved:\r\n\r\nuserfaultfd: fix checks for huge PMDs\r\n\r\nPatch series \u0026quot;userfaultfd: fix races around pmd_trans_huge() check\u0026quot;, v2.\r\n\r\nThe pmd_trans_huge() code in mfill_atomic() is wrong in three different\nways depending on kernel version:\r\n\r\n1. The pmd_trans_huge() check is racy and can lead to a BUG_ON() (if you hit\n the right two race windows) - I\u0026apos;ve tested this in a kernel build with\n some extra mdelay() calls. See the commit message for a description\n of the race scenario.\n On older kernels (before 6.5), I think the same bug can even\n theoretically lead to accessing transhuge page contents as a page table\n if you hit the right 5 narrow race windows (I haven\u0026apos;t tested this case).\n2. As pointed out by Qi Zheng, pmd_trans_huge() is not sufficient for\n detecting PMDs that don\u0026apos;t point to page tables.\n On older kernels (before 6.5), you\u0026apos;d just have to win a single fairly\n wide race to hit this.\n I\u0026apos;ve tested this on 6.1 stable by racing migration (with a mdelay()\n patched into try_to_migrate()) against UFFDIO_ZEROPAGE - on my x86\n VM, that causes a kernel oops in ptlock_ptr().\n3. On newer kernels (\u0026gt;=6.5), for shmem mappings, khugepaged is allowed\n to yank page tables out from under us (though I haven\u0026apos;t tested that),\n so I think the BUG_ON() checks in mfill_atomic() are just wrong.\r\n\r\nI decided to write two separate fixes for these (one fix for bugs 1+2, one\nfix for bug 3), so that the first fix can be backported to kernels\naffected by bugs 1+2.\r\n\r\n\nThis patch (of 2):\r\n\r\nThis fixes two issues.\r\n\r\nI discovered that the following race can occur:\r\n\r\n mfill_atomic other thread\n ============ ============\n \u0026lt;zap PMD\u0026gt;\n pmdp_get_lockless() [reads none pmd]\n \u0026lt;bail if trans_huge\u0026gt;\n \u0026lt;if none:\u0026gt;\n \u0026lt;pagefault creates transhuge zeropage\u0026gt;\n __pte_alloc [no-op]\n \u0026lt;zap PMD\u0026gt;\n \u0026lt;bail if pmd_trans_huge(*dst_pmd)\u0026gt;\n BUG_ON(pmd_none(*dst_pmd))\r\n\r\nI have experimentally verified this in a kernel with extra mdelay() calls;\nthe BUG_ON(pmd_none(*dst_pmd)) triggers.\r\n\r\nOn kernels newer than commit 0d940a9b270b (\u0026quot;mm/pgtable: allow\npte_offset_map[_lock]() to fail\u0026quot;), this can\u0026apos;t lead to anything worse than\na BUG_ON(), since the page table access helpers are actually designed to\ndeal with page tables concurrently disappearing; but on older kernels\n(\u0026lt;=6.4), I think we could probably theoretically race past the two\nBUG_ON() checks and end up treating a hugepage as a page table.\r\n\r\nThe second issue is that, as Qi Zheng pointed out, there are other types\nof huge PMDs that pmd_trans_huge() can\u0026apos;t catch: devmap PMDs and swap PMDs\n(in particular, migration PMDs).\r\n\r\nOn \u0026lt;=6.4, this is worse than the first issue: If mfill_atomic() runs on a\nPMD that contains a migration entry (which just requires winning a single,\nfairly wide race), it will pass the PMD to pte_offset_map_lock(), which\nassumes that the PMD points to a page table.\r\n\r\nBreakage follows: First, the kernel tries to take the PTE lock (which will\ncrash or maybe worse if there is no \u0026quot;struct page\u0026quot; for the address bits in\nthe migration entry PMD - I think at least on X86 there usually is no\ncorresponding \u0026quot;struct page\u0026quot; thanks to the PTE inversion mitigation, amd64\nlooks different).\r\n\r\nIf that didn\u0026apos;t crash, the kernel would next try to write a PTE into what\nit wrongly thinks is a page table.\r\n\r\nAs part of fixing these issues, get rid of the check for pmd_trans_huge()\nbefore __pte_alloc() - that\u0026apos;s redundant, we\u0026apos;re going to have to check for\nthat after the __pte_alloc() anyway.\r\n\r\nBackport note: pmdp_get_lockless() is pmd_read_atomic() in older kernels.(CVE-2024-46787)\r\n\r\nIn the Linux kernel, the following vulnerability has been resolved:\r\n\r\nsch/netem: fix use after free in netem_dequeue\r\n\r\nIf netem_dequeue() enqueues packet to inner qdisc and that qdisc\nreturns __NET_XMIT_STOLEN.

Vulnerability from osv_openeuler
The Linux Kernel, the operating system core itself.
Security Fix(es):
In the Linux kernel, the following vulnerability has been resolved:
NFSD: Fix ia_size underflow
iattr::ia_size is a loff_t, which is a signed 64-bit type. NFSv3 and NFSv4 both define file size as an unsigned 64-bit type. Thus there is a range of valid file size values an NFS client can send that is already larger than Linux can handle.
Currently decode_fattr4() dumps a full u64 value into ia_size. If that value happens to be larger than S64_MAX, then ia_size underflows. I'm about to fix up the NFSv3 behavior as well, so let's catch the underflow in the common code path: nfsd_setattr().(CVE-2022-48828)

misc: fastrpc: Fix use-after-free race condition for maps
It is possible that in between calling fastrpc_map_get() until map->fl->lock is taken in fastrpc_free_map(), another thread can call fastrpc_map_lookup() and get a reference to a map that is about to be deleted.
Rewrite fastrpc_map_get() to only increase the reference count of a map if it's non-zero. Propagate this to callers so they can know if a map is about to be deleted.

drm/amd/pm: fix a double-free in si_dpm_init
When the allocation of adev->pm.dpm.dyn_state.vddc_dependency_on_dispclk.entries fails, amdgpu_free_extended_power_table is called to free some fields of adev. However, when the control flow returns to si_dpm_sw_init, it goes to label dpm_failed and calls si_dpm_fini, which calls amdgpu_free_extended_power_table again and free those fields again. Thus a double-free is triggered.(CVE-2023-52691)
In the Linux kernel, the following vulnerability has been resolved:
f2fs: avoid format-overflow warning
With gcc and W=1 option, there's a warning like this:

usb: gadget: f_ncm: fix potential NULL ptr deref in ncm_bitrate()
In Google internal bug 265639009 we've received an (as yet) unreproducible crash report from an aarch64 GKI 5.10.149-android13 running device.
AFAICT the source code is at: https://android.googlesource.com/kernel/common/+/refs/tags/ASB-2022-12-05_13-5.10
The call stack is: ncm_close() -> ncm_notify() -> ncm_do_notify() with the crash at: ncm_do_notify+0x98/0x270 Code: 79000d0b b9000a6c f940012a f9400269 (b9405d4b)
Which I believe disassembles to (I don't know ARM assembly, but it looks sane enough to me...):
// halfword (16-bit) store presumably to event->wLength (at offset 6 of struct usb_cdc_notification) 0B 0D 00 79 strh w11, [x8, #6]
// word (32-bit) store presumably to req->Length (at offset 8 of struct usb_request) 6C 0A 00 B9 str w12, [x19, #8]
// x10 (NULL) was read here from offset 0 of valid pointer x9 // IMHO we're reading 'cdev->gadget' and getting NULL // gadget is indeed at offset 0 of struct usb_composite_dev 2A 01 40 F9 ldr x10, [x9]
// loading req->buf pointer, which is at offset 0 of struct usb_request 69 02 40 F9 ldr x9, [x19]
// x10 is null, crash, appears to be attempt to read cdev->gadget->max_speed 4B 5D 40 B9 ldr w11, [x10, #0x5c]
which seems to line up with ncm_do_notify() case NCM_NOTIFY_SPEED code fragment:
event->wLength = cpu_to_le16(8); req->length = NCM_STATUS_BYTECOUNT;
/ SPEED_CHANGE data is up/down speeds in bits/sec / data = req->buf + sizeof *event; data[0] = cpu_to_le32(ncm_bitrate(cdev->gadget));
My analysis of registers and NULL ptr deref crash offset (Unable to handle kernel NULL pointer dereference at virtual address 000000000000005c) heavily suggests that the crash is due to 'cdev->gadget' being NULL when executing: data[0] = cpu_to_le32(ncm_bitrate(cdev->gadget)); which calls: ncm_bitrate(NULL) which then calls: gadget_is_superspeed(NULL) which reads ((struct usb_gadget *)NULL)->max_speed and hits a panic.
AFAICT, if I'm counting right, the offset of max_speed is indeed 0x5C. (remember there's a GKI KABI reservation of 16 bytes in struct work_struct)
It's not at all clear to me how this is all supposed to work... but returning 0 seems much better than panic-ing...(CVE-2023-52894)
In the Linux kernel, the following vulnerability has been resolved:
nilfs2: fix general protection fault in nilfs_btree_insert()
If nilfs2 reads a corrupted disk image and tries to reads a b-tree node block by calling __nilfs_btree_get_block() against an invalid virtual block address, it returns -ENOENT because conversion of the virtual block address to a disk block address fails. However, this return value is the same as the internal code that b-tree lookup routines return to indicate that the block being searched does not exist, so functions that operate on that b-tree may misbehave.
When nilfs_btree_insert() receives this spurious 'not found' code from nilfs_btree_do_lookup(), it misunderstands that the 'not found' check was successful and continues the insert operation using incomplete lookup path data, causing the following crash:

This patch fixes the root cause of this problem by replacing the error code that __nilfs_btree_get_block() returns on block address conversion failure from -ENOENT to another internal code -EINVAL which means that the b-tree metadata is corrupted.
By returning -EINVAL, it propagates without glitches, and for all relevant b-tree operations, functions in the upper bmap layer output an error message indicating corrupted b-tree metadata via nilfs_bmap_convert_error(), and code -EIO will be eventually returned as it should be.(CVE-2023-52900)

nilfs2: add missing check for inode numbers on directory entries
Syzbot reported that mounting and unmounting a specific pattern of corrupted nilfs2 filesystem images causes a use-after-free of metadata file inodes, which triggers a kernel bug in lru_add_fn().
As Jan Kara pointed out, this is because the link count of a metadata file gets corrupted to 0, and nilfs_evict_inode(), which is called from iput(), tries to delete that inode (ifile inode in this case).
The inconsistency occurs because directories containing the inode numbers of these metadata files that should not be visible in the namespace are read without checking.
Fix this issue by treating the inode numbers of these internal files as errors in the sanity check helper when reading directory folios/pages.

x86/mm: Fix pti_clone_pgtable() alignment assumption
Guenter reported dodgy crashes on an i386-nosmp build using GCC-11 that had the form of endless traps until entry stack exhaust and then
DF from the stack guard.
It turned out that pti_clone_pgtable() had alignment assumptions on the start address, notably it hard assumes start is PMD aligned. This is true on x86_64, but very much not true on i386.
These assumptions can cause the end condition to malfunction, leading to a 'short' clone. Guess what happens when the user mapping has a short copy of the entry text?

select_local_address() and select_signal_address() both select an endpoint entry from the list inside an RCU protected section, but return a reference to it, to be read later on. If the entry is dereferenced after the RCU unlock, reading info could cause a Use-after-Free.
A simple solution is to copy the required info while inside the RCU protected section to avoid any risk of UaF later. The address ID might need to be modified later to handle the ID0 case later, so a copy seems OK to deal with.(CVE-2024-44974)
In the Linux kernel, the following vulnerability has been resolved:
net: hns3: fix a deadlock problem when config TC during resetting
When config TC during the reset process, may cause a deadlock, the flow is as below: pf reset start │ ▼ ...... setup tc │ │ ▼ ▼ DOWN: napi_disable() napi_disable()(skip) │ │ │ ▼ ▼ ...... ...... │ │ ▼ │ napi_enable() │ ▼ UINIT: netif_napi_del() │ ▼ ...... │ ▼ INIT: netif_napi_add() │ ▼ ...... global reset start │ │ ▼ ▼ UP: napi_enable()(skip) ...... │ │ ▼ ▼ ...... napi_disable()
In reset process, the driver will DOWN the port and then UINIT, in this case, the setup tc process will UP the port before UINIT, so cause the problem. Adds a DOWN process in UINIT to fix it.(CVE-2024-44995)

In the Linux kernel, the following vulnerability has been resolved:
vfs: Don't evict inode under the inode lru traversing context
The inode reclaiming process(See function prune_icache_sb) collects all reclaimable inodes and mark them with I_FREEING flag at first, at that time, other processes will be stuck if they try getting these inodes (See function find_inode_fast), then the reclaiming process destroy the inodes by function dispose_list(). Some filesystems(eg. ext4 with ea_inode feature, ubifs with xattr) may do inode lookup in the inode evicting callback function, if the inode lookup is operated under the inode lru traversing context, deadlock problems may happen.
Case 1: In function ext4_evict_inode(), the ea inode lookup could happen if ea_inode feature is enabled, the lookup process will be stuck under the evicting context like this:
- File A has inode i_reg and an ea inode i_ea
- getfattr(A, xattr_buf) // i_ea is added into lru // lru->i_ea
-
Then, following three processes running like this:
PA PB echo 2 > /proc/sys/vm/drop_caches shrink_slab prune_dcache_sb // i_reg is added into lru, lru->i_ea->i_reg prune_icache_sb list_lru_walk_one inode_lru_isolate i_ea->i_state |= I_FREEING // set inode state inode_lru_isolate __iget(i_reg) spin_unlock(&i_reg->i_lock) spin_unlock(lru_lock) rm file A i_reg->nlink = 0 iput(i_reg) // i_reg->nlink is 0, do evict ext4_evict_inode ext4_xattr_delete_inode ext4_xattr_inode_dec_ref_all ext4_xattr_inode_iget ext4_iget(i_ea->i_ino) iget_locked find_inode_fast __wait_on_freeing_inode(i_ea) ----→ AA deadlock dispose_list // cannot be executed by prune_icache_sb wake_up_bit(&i_ea->i_state)
Case 2: In deleted inode writing function ubifs_jnl_write_inode(), file deleting process holds BASEHD's wbuf->io_mutex while getting the xattr inode, which could race with inode reclaiming process(The reclaiming process could try locking BASEHD's wbuf->io_mutex in inode evicting function), then an ABBA deadlock problem would happen as following:
- File A has inode ia and a xattr(with inode ixa), regular file B has inode ib and a xattr.
- getfattr(A, xattr_buf) // ixa is added into lru // lru->ixa
- Then, following three processes running like this:
PA PB PC echo 2 > /proc/sys/vm/drop_caches shrink_slab prune_dcache_sb // ib and ia are added into lru, lru->ixa->ib->ia prune_icache_sb list_lru_walk_one inode_lru_isolate ixa->i_state |= I_FREEING // set inode state inode_lru_isolate __iget(ib) spin_unlock(&ib->i_lock) spin_unlock(lru_lock) rm file B ib->nlink = 0rm file A iput(ia) ubifs_evict_inode(ia) ubifs_jnl_delete_inode(ia) ubifs_jnl_write_inode(ia) make_reservation(BASEHD) // Lock wbuf->io_mutex ubifs_iget(ixa->i_ino) iget_locked find_inode_fast __wait_on_freeing_inode(ixa) | iput(ib) // ib->nlink is 0, do evict | ubifs_evict_inode | ubifs_jnl_delete_inode(ib) ↓ ubifs_jnl_write_inode ABBA deadlock ←-----make_reservation(BASEHD) dispose_list // cannot be executed by prune_icache_sb wake_up_bit(&ixa->i_state)

In the Linux kernel, the following vulnerability has been resolved:
mmc: mmc_test: Fix NULL dereference on allocation failure

In the Linux kernel, the following vulnerability has been resolved:
btrfs: fix qgroup reserve leaks in cow_file_range
In the buffered write path, the dirty page owns the qgroup reserve until it creates an ordered_extent.
Therefore, any errors that occur before the ordered_extent is created must free that reservation, or else the space is leaked. The fstest generic/475 exercises various IO error paths, and is able to trigger errors in cow_file_range where we fail to get to allocating the ordered extent. Note that because we do clear delalloc, we are likely to remove the inode from the delalloc list, so the inodes/pages to not have invalidate/launder called on them in the commit abort path.
This results in failures at the unmount stage of the test that look like:

In the Linux kernel, the following vulnerability has been resolved:
Squashfs: sanity check symbolic link size
Syzkiller reports a "KMSAN: uninit-value in pick_link" bug.
This is caused by an uninitialised page, which is ultimately caused by a corrupted symbolic link size read from disk.
The reason why the corrupted symlink size causes an uninitialised page is due to the following sequence of events:
-
squashfs_read_inode() is called to read the symbolic link from disk. This assigns the corrupted value 3875536935 to inode->i_size.
-
Later squashfs_symlink_read_folio() is called, which assigns this corrupted value to the length variable, which being a signed int, overflows producing a negative number.
-
The following loop that fills in the page contents checks that the copied bytes is less than length, which being negative means the loop is skipped, producing an uninitialised page.
This patch adds a sanity check which checks that the symbolic link size is not larger than expected.

V2: fix spelling mistake.(CVE-2024-46744)
In the Linux kernel, the following vulnerability has been resolved:
Input: uinput - reject requests with unreasonable number of slots
When exercising uinput interface syzkaller may try setting up device with a really large number of slots, which causes memory allocation failure in input_mt_init_slots(). While this allocation failure is handled properly and request is rejected, it results in syzkaller reports. Additionally, such request may put undue burden on the system which will try to free a lot of memory for a bogus request.
Fix it by limiting allowed number of slots to 100. This can easily be extended if we see devices that can track more than 100 contacts.(CVE-2024-46745)

Instead of a BUG_ON() just return an error, log an error message and abort the transaction in case we find an extent buffer belonging to the relocation tree that doesn't have the full backref flag set. This is unexpected and should never happen (save for bugs or a potential bad memory).(CVE-2024-46752)
In the Linux kernel, the following vulnerability has been resolved:
userfaultfd: fix checks for huge PMDs
Patch series "userfaultfd: fix races around pmd_trans_huge() check", v2.
The pmd_trans_huge() code in mfill_atomic() is wrong in three different ways depending on kernel version:
- The pmd_trans_huge() check is racy and can lead to a BUG_ON() (if you hit the right two race windows) - I've tested this in a kernel build with some extra mdelay() calls. See the commit message for a description of the race scenario. On older kernels (before 6.5), I think the same bug can even theoretically lead to accessing transhuge page contents as a page table if you hit the right 5 narrow race windows (I haven't tested this case).
- As pointed out by Qi Zheng, pmd_trans_huge() is not sufficient for detecting PMDs that don't point to page tables. On older kernels (before 6.5), you'd just have to win a single fairly wide race to hit this. I've tested this on 6.1 stable by racing migration (with a mdelay() patched into try_to_migrate()) against UFFDIO_ZEROPAGE - on my x86 VM, that causes a kernel oops in ptlock_ptr().
- On newer kernels (>=6.5), for shmem mappings, khugepaged is allowed to yank page tables out from under us (though I haven't tested that), so I think the BUG_ON() checks in mfill_atomic() are just wrong.
I decided to write two separate fixes for these (one fix for bugs 1+2, one fix for bug 3), so that the first fix can be backported to kernels affected by bugs 1+2.
This patch (of 2):
This fixes two issues.
I discovered that the following race can occur:
mfill_atomic other thread ============ ============ <zap PMD> pmdp_get_lockless() [reads none pmd] <bail if trans_huge> <if none:> <pagefault creates transhuge zeropage> __pte_alloc [no-op] <zap PMD> <bail if pmd_trans_huge(dst_pmd)> BUG_ON(pmd_none(dst_pmd))
I have experimentally verified this in a kernel with extra mdelay() calls; the BUG_ON(pmd_none(*dst_pmd)) triggers.
On kernels newer than commit 0d940a9b270b ("mm/pgtable: allow pte_offset_map_lock to fail"), this can't lead to anything worse than a BUG_ON(), since the page table access helpers are actually designed to deal with page tables concurrently disappearing; but on older kernels (<=6.4), I think we could probably theoretically race past the two BUG_ON() checks and end up treating a hugepage as a page table.
The second issue is that, as Qi Zheng pointed out, there are other types of huge PMDs that pmd_trans_huge() can't catch: devmap PMDs and swap PMDs (in particular, migration PMDs).
On <=6.4, this is worse than the first issue: If mfill_atomic() runs on a PMD that contains a migration entry (which just requires winning a single, fairly wide race), it will pass the PMD to pte_offset_map_lock(), which assumes that the PMD points to a page table.
Breakage follows: First, the kernel tries to take the PTE lock (which will crash or maybe worse if there is no "struct page" for the address bits in the migration entry PMD - I think at least on X86 there usually is no corresponding "struct page" thanks to the PTE inversion mitigation, amd64 looks different).
If that didn't crash, the kernel would next try to write a PTE into what it wrongly thinks is a page table.
As part of fixing these issues, get rid of the check for pmd_trans_huge() before __pte_alloc() - that's redundant, we're going to have to check for that after the __pte_alloc() anyway.
Backport note: pmdp_get_lockless() is pmd_read_atomic() in older kernels.(CVE-2024-46787)

entries\r\n\r\nSyzbot reported that mounting and unmounting a specific pattern of\ncorrupted nilfs2 filesystem images causes a use-after-free of metadata\nfile inodes, which triggers a kernel bug in lru_add_fn().\r\n\r\nAs Jan Kara pointed out, this is because the link count of a metadata file\ngets corrupted to 0, and nilfs_evict_inode(), which is called from iput(),\ntries to delete that inode (ifile inode in this case).\r\n\r\nThe inconsistency occurs because directories containing the inode numbers\nof these metadata files that should not be visible in the namespace are\nread without checking.\r\n\r\nFix this issue by treating the inode numbers of these internal files as\nerrors in the sanity check helper when reading directory folios/pages.\r\n\r\nAlso thanks to Hillf Danton and Matthew Wilcox for their initial mm-layer\nanalysis.(CVE-2024-42104)\r\n\r\nIn the Linux kernel, the following vulnerability has been resolved:\r\n\r\ndrm/amd/display: Skip finding free audio for

This can easily\nbe extended if we see devices that can track more than 100 contacts.(CVE-2024-46745)\r\n\r\nIn the Linux kernel, the following vulnerability has been resolved:\r\n\r\nHID: cougar: fix slab-out-of-bounds Read in cougar_report_fixup\r\n\r\nreport_fixup for the Cougar 500k Gaming Keyboard was not verifying\nthat the report descriptor size was correct before accessing it(CVE-2024-46747)\r\n\r\nIn the Linux kernel, the following vulnerability has been resolved:\r\n\r\nbtrfs: don\u0026apos;t BUG_ON() when 0 reference count at btrfs_lookup_extent_info()\r\n\r\nInstead of doing a BUG_ON() handle the error by returning -EUCLEAN,\naborting the transaction and logging an error message.(CVE-2024-46751)\r\n\r\nIn the Linux kernel, the following vulnerability has been resolved:\r\n\r\nbtrfs: replace BUG_ON() with error handling at update_ref_for_cow()\r\n\r\nInstead of a BUG_ON() just return an error, log an error message and\nabort the transaction in case we find an extent buffer belonging to the\nrelocation tree that doesn\u0026apos;t have the full backref flag set. This is\nunexpected and should never happen (save for bugs or a potential bad\nmemory).(CVE-2024-46752)\r\n\r\nIn the Linux kernel, the following vulnerability has been resolved:\r\n\r\nuserfaultfd: fix checks for huge PMDs\r\n\r\nPatch series \u0026quot;userfaultfd: fix races around pmd_trans_huge() check\u0026quot;, v2.\r\n\r\nThe pmd_trans_huge() code in mfill_atomic() is wrong in three different\nways depending on kernel version:\r\n\r\n1. The pmd_trans_huge() check is racy and can lead to a BUG_ON() (if you hit\n the right two race windows) - I\u0026apos;ve tested this in a kernel build with\n some extra mdelay() calls. See the commit message for a description\n of the race scenario.\n On older kernels (before 6.5), I think the same bug can even\n theoretically lead to accessing transhuge page contents as a page table\n if you hit the right 5 narrow race windows (I haven\u0026apos;t tested this case).\n2. As pointed out by Qi Zheng, pmd_trans_huge() is not sufficient for\n detecting PMDs that don\u0026apos;t point to page tables.\n On older kernels (before 6.5), you\u0026apos;d just have to win a single fairly\n wide race to hit this.\n I\u0026apos;ve tested this on 6.1 stable by racing migration (with a mdelay()\n patched into try_to_migrate()) against UFFDIO_ZEROPAGE - on my x86\n VM, that causes a kernel oops in ptlock_ptr().\n3. On newer kernels (\u0026gt;=6.5), for shmem mappings, khugepaged is allowed\n to yank page tables out from under us (though I haven\u0026apos;t tested that),\n so I think the BUG_ON() checks in mfill_atomic() are just wrong.\r\n\r\nI decided to write two separate fixes for these (one fix for bugs 1+2, one\nfix for bug 3), so that the first fix can be backported to kernels\naffected by bugs 1+2.\r\n\r\n\nThis patch (of 2):\r\n\r\nThis fixes two issues.\r\n\r\nI discovered that the following race can occur:\r\n\r\n mfill_atomic other thread\n ============ ============\n \u0026lt;zap PMD\u0026gt;\n pmdp_get_lockless() [reads none pmd]\n \u0026lt;bail if trans_huge\u0026gt;\n \u0026lt;if none:\u0026gt;\n \u0026lt;pagefault creates transhuge zeropage\u0026gt;\n __pte_alloc [no-op]\n \u0026lt;zap PMD\u0026gt;\n \u0026lt;bail if pmd_trans_huge(*dst_pmd)\u0026gt;\n BUG_ON(pmd_none(*dst_pmd))\r\n\r\nI have experimentally verified this in a kernel with extra mdelay() calls;\nthe BUG_ON(pmd_none(*dst_pmd)) triggers.\r\n\r\nOn kernels newer than commit 0d940a9b270b (\u0026quot;mm/pgtable: allow\npte_offset_map[_lock]() to fail\u0026quot;), this can\u0026apos;t lead to anything worse than\na BUG_ON(), since the page table access helpers are actually designed to\ndeal with page tables concurrently disappearing; but on older kernels\n(\u0026lt;=6.4), I think we could probably theoretically race past the two\nBUG_ON() checks and end up treating a hugepage as a page table.\r\n\r\nThe second issue is that, as Qi Zheng pointed out, there are other types\nof huge PMDs that pmd_trans_huge() can\u0026apos;t catch: devmap PMDs and swap PMDs\n(in particular, migration PMDs).\r\n\r\nOn \u0026lt;=6.4, this is worse than the first issue: If mfill_atomic() runs on a\nPMD that contains a migration entry (which just requires winning a single,\nfairly wide race), it will pass the PMD to pte_offset_map_lock(), which\nassumes that the PMD points to a page table.\r\n\r\nBreakage follows: First, the kernel tries to take the PTE lock (which will\ncrash or maybe worse if there is no \u0026quot;struct page\u0026quot; for the address bits in\nthe migration entry PMD - I think at least on X86 there usually is no\ncorresponding \u0026quot;struct page\u0026quot; thanks to the PTE inversion mitigation, amd64\nlooks different).\r\n\r\nIf that didn\u0026apos;t crash, the kernel would next try to write a PTE into what\nit wrongly thinks is a page table.\r\n\r\nAs part of fixing these issues, get rid of the check for pmd_trans_huge()\nbefore __pte_alloc() - that\u0026apos;s redundant, we\u0026apos;re going to have to check for\nthat after the __pte_alloc() anyway.\r\n\r\nBackport note: pmdp_get_lockless() is pmd_read_atomic() in older kernels.(CVE-2024-46787)",
