Vulnerability from github – Published: 2024-05-20 12:30 – Updated: 2026-05-12 12:31In the Linux kernel, the following vulnerability has been resolved:
ipv4: check for NULL idev in ip_route_use_hint()
syzbot was able to trigger a NULL deref in fib_validate_source() in an old tree [1].
It appears the bug exists in latest trees.
All calls to __in_dev_get_rcu() must be checked for a NULL result.

Vulnerability from osv_openeuler – Published: 2024-05-31 11:07 – Updated: 2026-08-06 11:07 – Source websiteThe Linux Kernel, the operating system core itself.
Security Fix(es):
In the Linux kernel, the following vulnerability has been resolved:
drm/amdgpu: handle the case of pci_channel_io_frozen only in amdgpu_pci_resume
In current code, when a PCI error state pci_channel_io_normal is detectd, it will report PCI_ERS_RESULT_CAN_RECOVER status to PCI driver, and PCI driver will continue the execution of PCI resume callback report_resume by pci_walk_bridge, and the callback will go into amdgpu_pci_resume finally, where write lock is releasd unconditionally without acquiring such lock first. In this case, a deadlock will happen when other threads start to acquire the read lock.
To fix this, add a member in amdgpu_device strucutre to cache pci_channel_state, and only continue the execution in amdgpu_pci_resume when it's pci_channel_io_frozen.(CVE-2021-47421)
In the Linux kernel, the following vulnerability has been resolved:
ptp: Fix possible memory leak in ptp_clock_register()
I got memory leak as follows when doing fault injection test:

When posix_clock_register() returns an error, the name allocated in dev_set_name() will be leaked, the put_device() should be used to give up the device reference, then the name will be freed in kobject_cleanup() and other memory will be freed in ptp_clock_release().(CVE-2021-47455)
In the Linux kernel, the following vulnerability has been resolved:
net: enetc: deny offload of tc-based TSN features on VF interfaces
TSN features on the ENETC (taprio, cbs, gate, police) are configured through a mix of command BD ring messages and port registers: enetc_port_rd(), enetc_port_wr().
Port registers are a region of the ENETC memory map which are only accessible from the PCIe Physical Function. They are not accessible from the Virtual Functions.
Moreover, attempting to access these registers crashes the kernel:

Split enetc_setup_tc() into separate functions for the PF and for the VF drivers. Also remove enetc_qos.o from being included into enetc-vf.ko, since it serves absolutely no purpose there.(CVE-2022-48645)
In the Linux kernel, the following vulnerability has been resolved:
drm/tegra: dsi: Add missing check for of_find_device_by_node
Add check for the return value of of_find_device_by_node() and return the error if it fails in order to avoid NULL pointer dereference.(CVE-2023-52650)
In the Linux kernel, the following vulnerability has been resolved:
NTB: fix possible name leak in ntb_register_device()
If device_register() fails in ntb_register_device(), the device name allocated by dev_set_name() should be freed. As per the comment in device_register(), callers should use put_device() to give up the reference in the error path. So fix this by calling put_device() in the error path so that the name can be freed in kobject_cleanup().
As a result of this, put_device() in the error path of ntb_register_device() is removed and the actual error is returned.
In the Linux kernel, the following vulnerability has been resolved:
SUNRPC: fix a memleak in gss_import_v2_context
The ctx->mech_used.data allocated by kmemdup is not freed in neither gss_import_v2_context nor it only caller gss_krb5_import_sec_context, which frees ctx on error.
Thus, this patch reform the last call of gss_import_v2_context to the gss_krb5_import_ctx_v2, preventing the memleak while keepping the return formation.(CVE-2023-52653)
In the Linux kernel, the following vulnerability has been resolved:
io_uring: drop any code related to SCM_RIGHTS
This is dead code after we dropped support for passing io_uring fds over SCM_RIGHTS, get rid of it.(CVE-2023-52656)
In the Linux kernel, the following vulnerability has been resolved:
net: atlantic: eliminate double free in error handling logic
Driver has a logic leak in ring data allocation/free, where aq_ring_free could be called multiple times on same ring, if system is under stress and got memory allocation error.
Ring pointer was used as an indicator of failure, but this is not correct since only ring data is allocated/deallocated. Ring itself is an array member.
Changing ring allocation functions to return error code directly. This simplifies error handling and eliminates aq_ring_free on higher layer.(CVE-2023-52664)
In the Linux kernel, the following vulnerability has been resolved:
ALSA: scarlett2: Add clamp() in scarlett2_mixer_ctl_put()
Ensure the value passed to scarlett2_mixer_ctl_put() is between 0 and SCARLETT2_MIXER_MAX_VALUE so we don't attempt to access outside scarlett2_mixer_values[].(CVE-2023-52674)
In the Linux kernel, the following vulnerability has been resolved:
ACPI: LPIT: Avoid u32 multiplication overflow
In lpit_update_residency() there is a possibility of overflow in multiplication, if tsc_khz is large enough (> UINT_MAX/1000).
Change multiplication to mul_u32_u32().
Found by Linux Verification Center (linuxtesting.org) with SVACE.(CVE-2023-52683)
In the Linux kernel, the following vulnerability has been resolved:
calipso: fix memory leak in netlbl_calipso_add_pass()
If IPv6 support is disabled at boot (ipv6.disable=1), the calipso_init() -> netlbl_calipso_ops_register() function isn't called, and the netlbl_calipso_ops_get() function always returns NULL. In this case, the netlbl_calipso_add_pass() function allocates memory for the doi_def variable but doesn't free it with the calipso_doi_free().

TIPC bearer-related names including link names must be null-terminated strings. If a link name which is not null-terminated is passed through netlink, strstr() and similar functions can cause buffer overrun. This causes the above issue.
This patch changes the nla_policy for bearer-related names from NLA_STRING to NLA_NUL_STRING. This resolves the issue by ensuring that only null-terminated strings are accepted as bearer-related names.
syzbot reported similar uninit-value issue related to bearer names [2]. The root cause of this issue is that a non-null-terminated bearer name was passed. This patch also resolved this issue.(CVE-2023-52845)

hsr: Prevent use after free in prp_create_tagged_frame()
The prp_fill_rct() function can fail. In that situation, it frees the skb and returns NULL. Meanwhile on the success path, it returns the original skb. So it's straight forward to fix bug by using the returned value.(CVE-2023-52846)
In the Linux kernel, the following vulnerability has been resolved:
media: bttv: fix use after free error due to btv->timeout timer
There may be some a race condition between timer function bttv_irq_timeout and bttv_remove. The timer is setup in probe and there is no timer_delete operation in remove function. When it hit kfree btv, the function might still be invoked, which will cause use after free bug.
This bug is found by static analysis, it may be false positive.
Fix it by adding del_timer_sync invoking to the remove function.

padata: Fix refcnt handling in padata_free_shell()
In a high-load arm64 environment, the pcrypt_aead01 test in LTP can lead to system UAF (Use-After-Free) issues. Due to the lengthy analysis of the pcrypt_aead01 function call, I'll describe the problem scenario using a simplified model:
Suppose there's a user of padata named user_function that adheres to
the padata requirement of calling padata_free_shell after serial()
has been invoked, as demonstrated in the following code:
struct request {
struct padata_priv padata;
struct completion *done;
};
void parallel(struct padata_priv *padata) {
do_something();
}
void serial(struct padata_priv *padata) {
struct request *request = container_of(padata,
struct request,
padata);
complete(request->done);
}
void user_function() {
DECLARE_COMPLETION(done)
padata->parallel = parallel;
padata->serial = serial;
padata_do_parallel();
wait_for_completion(&done);
padata_free_shell();
}
In the corresponding padata.c file, there's the following code:
static void padata_serial_worker(struct work_struct *serial_work) {
...
cnt = 0;
while (!list_empty(&local_list)) {
...
padata->serial(padata);
cnt++;
}
local_bh_enable();
if (refcount_sub_and_test(cnt, &pd->refcnt))
padata_free_pd(pd);
}
Because of the high system load and the accumulation of unexecuted
softirq at this moment, local_bh_enable() in padata takes longer
to execute than usual. Subsequently, when accessing pd->refcnt,
pd has already been released by padata_free_shell(), resulting
in a UAF issue with pd->refcnt.
The fix is straightforward: add refcount_dec_and_test before calling
padata_free_pd in padata_free_shell.(CVE-2023-52854)

tracing: Have trace_event_file have ref counters
The following can crash the kernel:
# cd /sys/kernel/tracing # echo 'p:sched schedule' > kprobe_events # exec 5>>events/kprobes/sched/enable # > kprobe_events # exec 5>&-
The above commands:
- Change directory to the tracefs directory
- Create a kprobe event (doesn't matter what one)
- Open bash file descriptor 5 on the enable file of the kprobe event
- Delete the kprobe event (removes the files too)
- Close the bash file descriptor 5
The above causes a crash!
BUG: kernel NULL pointer dereference, address: 0000000000000028 #PF: supervisor read access in kernel mode #PF: error_code(0x0000) - not-present page PGD 0 P4D 0 Oops: 0000 [#1] PREEMPT SMP PTI CPU: 6 PID: 877 Comm: bash Not tainted 6.5.0-rc4-test-00008-g2c6b6b1029d4-dirty #186 Hardware name: QEMU Standard PC (Q35 + ICH9, 2009), BIOS 1.16.2-debian-1.16.2-1 04/01/2014 RIP: 0010:tracing_release_file_tr+0xc/0x50
What happens here is that the kprobe event creates a trace_event_file "file" descriptor that represents the file in tracefs to the event. It maintains state of the event (is it enabled for the given instance?). Opening the "enable" file gets a reference to the event "file" descriptor via the open file descriptor. When the kprobe event is deleted, the file is also deleted from the tracefs system which also frees the event "file" descriptor.
But as the tracefs file is still opened by user space, it will not be totally removed until the final dput() is called on it. But this is not true with the event "file" descriptor that is already freed. If the user does a write to or simply closes the file descriptor it will reference the event "file" descriptor that was just freed, causing a use-after-free bug.
To solve this, add a ref count to the event "file" descriptor as well as a new flag called "FREED". The "file" will not be freed until the last reference is released. But the FREE flag will be set when the event is removed to prevent any more modifications to that event from happening, even if there's still a reference to the event "file" descriptor.(CVE-2023-52879)
In the Linux kernel, the following vulnerability has been resolved:
netfilter: nf_tables: mark set as dead when unbinding anonymous set with timeout
While the rhashtable set gc runs asynchronously, a race allows it to collect elements from anonymous sets with timeouts while it is being released from the commit path.
Mingi Cho originally reported this issue in a different path in 6.1.x with a pipapo set with low timeouts which is not possible upstream since 7395dfacfff6 ("netfilter: nf_tables: use timestamp to check for set element timeout").
Fix this by setting on the dead flag for anonymous sets to skip async gc in this case.
According to 08e4c8c5919f ("netfilter: nf_tables: mark newset as dead on transaction abort"), Florian plans to accelerate abort path by releasing objects via workqueue, therefore, this sets on the dead flag for abort path too.(CVE-2024-26643)
In the Linux kernel, the following vulnerability has been resolved:
wireguard: netlink: access device through ctx instead of peer
The previous commit fixed a bug that led to a NULL peer->device being dereferenced. It's actually easier and faster performance-wise to instead get the device from ctx->wg. This semantically makes more sense too, since ctx->wg->peer_allowedips.seq is compared with ctx->allowedips_seq, basing them both in ctx. This also acts as a defence in depth provision against freed peers.(CVE-2024-26950)
In the Linux kernel, the following vulnerability has been resolved:
nilfs2: prevent kernel bug at submit_bh_wbc()
Fix a bug where nilfs_get_block() returns a successful status when searching and inserting the specified block both fail inconsistently. If this inconsistent behavior is not due to a previously fixed bug, then an unexpected race is occurring, so return a temporary error -EAGAIN instead.
This prevents callers such as __block_write_begin_int() from requesting a read into a buffer that is not mapped, which would cause the BUG_ON check for the BH_Mapped flag in submit_bh_wbc() to fail.(CVE-2024-26955)

s390/zcrypt: fix reference counting on zcrypt card objects
Tests with hot-plugging crytpo cards on KVM guests with debug kernel build revealed an use after free for the load field of the struct zcrypt_card. The reason was an incorrect reference handling of the zcrypt card object which could lead to a free of the zcrypt card object while it was still in use.

This is because we're completing the nfs_direct_request twice in a row.
The source of this is when we have our commit requests to submit, we process them and send them off, and then in the completion path for the commit requests we have
if (nfs_commit_end(cinfo.mds)) nfs_direct_write_complete(dreq);
However since we're submitting asynchronous requests we sometimes have one that completes before we submit the next one, so we end up calling complete on the nfs_direct_request twice.
The only other place we use nfs_generic_commit_list() is in __nfs_commit_inode, which wraps this call in a
nfs_commit_begin(); nfs_commit_end();
Which is a common pattern for this style of completion handling, one that is also repeated in the direct code with get_dreq()/put_dreq() calls around where we process events as well as in the completion paths.
Fix this by using the same pattern for the commit requests.
Before with my 200 node rocksdb stress running this warning would pop every 10ish minutes. With my patch the stress test has been running for several hours without popping.(CVE-2024-26958)

ubifs: ubifs_symlink: Fix memleak of inode->i_link in error path
For error handling path in ubifs_symlink(), inode will be marked as bad first, then iput() is invoked. If inode->i_link is initialized by fscrypt_encrypt_symlink() in encryption scenario, inode->i_link won't be freed by callchain ubifs_free_inode -> fscrypt_free_inode in error handling path, because make_bad_inode() has changed 'inode->i_mode' as 'S_IFREG'.

Free inode->i_link before marking inode bad. Method 2 is picked, it has less influence, personally, I think.(CVE-2024-26972)

KVM: Always flush async #PF workqueue when vCPU is being destroyed
Always flush the per-vCPU async #PF workqueue when a vCPU is clearing its completion queue, e.g. when a VM and all its vCPUs is being destroyed. KVM must ensure that none of its workqueue callbacks is running when the last reference to the KVM module is put. Gifting a reference to the associated VM prevents the workqueue callback from dereferencing freed vCPU/VM memory, but does not prevent the KVM module from being unloaded before the callback completes.
Drop the misguided VM refcount gifting, as calling kvm_put_kvm() from async_pf_execute() if kvm_put_kvm() flushes the async #PF workqueue will result in deadlock. async_pf_execute() can't return until kvm_put_kvm() finishes, and kvm_put_kvm() can't return until async_pf_execute() finishes:

If kvm_clear_async_pf_completion_queue() actually flushes the workqueue, then there's no need to gift async_pf_execute() a reference because all invocations of async_pf_execute() will be forced to complete before the vCPU and its VM are destroyed/freed. And that in turn fixes the module unloading bug as __fput() won't do module_put() on the last vCPU reference until the vCPU has been freed, e.g. if closing the vCPU file also puts the last reference to the KVM module.
Note that kvm_check_async_pf_completion() may also take the work item off the completion queue and so also needs to flush the work queue, as the work will not be seen by kvm_clear_async_pf_completion_queue(). Waiting on the workqueue could theoretically delay a vCPU due to waiting for the work to complete, but that's a very, very small chance, and likely a very small delay. kvm_arch_async_page_present_queued() unconditionally makes a new request, i.e. will effectively delay entering the guest, so the remaining work is really just:
trace_kvm_async_pf_completed(addr, cr2_or_gpa);
__kvm_vcpu_wake_up(vcpu);
mmput(mm);
and mmput() can't drop the last reference to the page tables if the vCPU is still alive, i.e. the vCPU won't get stuck tearing down page tables.
Add a helper to do the flushing, specifically to deal with "wakeup all" work items, as they aren't actually work items, i.e. are never placed in a workqueue. Trying to flush a bogus workqueue entry rightly makes __flush_work() complain (kudos to whoever added that sanity check).

In the Linux kernel, the following vulnerability has been resolved:
Squashfs: check the inode number is not the invalid value of zero
Syskiller has produced an out of bounds access in fill_meta_index().
That out of bounds access is ultimately caused because the inode has an inode number with the invalid value of zero, which was not checked.
The reason this causes the out of bounds access is due to following sequence of events:
-
Fill_meta_index() is called to allocate (via empty_meta_index()) and fill a metadata index. It however suffers a data read error and aborts, invalidating the newly returned empty metadata index. It does this by setting the inode number of the index to zero, which means unused (zero is not a valid inode number).
-
When fill_meta_index() is subsequently called again on another read operation, locate_meta_index() returns the previous index because it matches the inode number of 0. Because this index has been returned it is expected to have been filled, and because it hasn't been, an out of bounds access is performed.
This patch adds a sanity check which checks that the inode number is not zero when the inode is created and returns -EINVAL if it is.

fs: sysfs: Fix reference leak in sysfs_break_active_protection()
The sysfs_break_active_protection() routine has an obvious reference leak in its error path. If the call to kernfs_find_and_get() fails then kn will be NULL, so the companion sysfs_unbreak_active_protection() routine won't get called (and would only cause an access violation by trying to dereference kn->parent if it was called). As a result, the reference to kobj acquired at the start of the function will never be released.
Fix the leak by adding an explicit kobject_put() call when kn is NULL.(CVE-2024-26993)

serial/pmac_zilog: Remove flawed mitigation for rx irq flood
The mitigation was intended to stop the irq completely. That may be better than a hard lock-up but it turns out that you get a crash anyway if you're using pmac_zilog as a serial console:
ttyPZ0: pmz: rx irq flood ! BUG: spinlock recursion on CPU#0, swapper/0
That's because the pr_err() call in pmz_receive_chars() results in pmz_console_write() attempting to lock a spinlock already locked in pmz_interrupt(). With CONFIG_DEBUG_SPINLOCK=y, this produces a fatal BUG splat. The spinlock in question is the one in struct uart_port.
Even when it's not fatal, the serial port rx function ceases to work. Also, the iteration limit doesn't play nicely with QEMU, as can be seen in the bug report linked below.
A web search for other reports of the error message "pmz: rx irq flood" didn't produce anything. So I don't think this code is needed any more. Remove it.(CVE-2024-26999)

In the Linux kernel, the following vulnerability has been resolved:
USB: usb-storage: Prevent divide-by-0 error in isd200_ata_command
The isd200 sub-driver in usb-storage uses the HEADS and SECTORS values in the ATA ID information to calculate cylinder and head values when creating a CDB for READ or WRITE commands. The calculation involves division and modulus operations, which will cause a crash if either of these values is 0. While this never happens with a genuine device, it could happen with a flawed or subversive emulation, as reported by the syzbot fuzzer.
Protect against this possibility by refusing to bind to the device if either the ATA_ID_HEADS or ATA_ID_SECTORS value in the device's ID information is 0. This requires isd200_Initialization() to return a negative error code when initialization fails; currently it always returns 0 (even when there is an error).(CVE-2024-27059)

Using the combo of d_drop()/dput() (as mentioned in Documentation/filesystems/vfs.rst) isn't the right approach here, and leads to the reference counting problem seen above. Use d_invalidate() and update the code to not bother checking for error codes that can never happen.

In the Linux kernel, the following vulnerability has been resolved: x86/fpu: Keep xfd_state in sync with MSR_IA32_XFD Commit 672365477ae8 ("x86/fpu: Update XFD state where required") and commit 8bf26758ca96 ("x86/fpu: Add XFD state to fpstate") introduced a per CPU variable xfd_state to keep the MSR_IA32_XFD value cached, in order to avoid unnecessary writes to the MSR. On CPU hotplug MSR_IA32_XFD is reset to the init_fpstate.xfd, which wipes out any stale state. But the per CPU cached xfd value is not reset, which brings them out of sync. As a consequence a subsequent xfd_update_state() might fail to update the MSR which in turn can result in XRSTOR raising a #NM in kernel space, which crashes the kernel. To fix this, introduce xfd_set_state() to write xfd_state together with MSR_IA32_XFD, and use it in all places that set MSR_IA32_XFD.(CVE-2024-35801)

The first kiocb_set_cancel_fn() argument may point at a struct kiocb that is not embedded inside struct aio_kiocb. With the current code, depending on the compiler, the req->ki_ctx read happens either before the IOCB_AIO_RW test or after that test. Move the req->ki_ctx read such that it is guaranteed that the IOCB_AIO_RW test happens first.(CVE-2024-35815)

LoongArch: Define the __io_aw() hook as mmiowb()
Commit fb24ea52f78e0d595852e ("drivers: Remove explicit invocations of mmiowb()") remove all mmiowb() in drivers, but it says:
"NOTE: mmiowb() has only ever guaranteed ordering in conjunction with spin_unlock(). However, pairing each mmiowb() removal in this patch with the corresponding call to spin_unlock() is not at all trivial, so there is a small chance that this change may regress any drivers incorrectly relying on mmiowb() to order MMIO writes between CPUs using lock-free synchronisation."
The mmio in radeon_ring_commit() is protected by a mutex rather than a spinlock, but in the mutex fastpath it behaves similar to spinlock. We can add mmiowb() calls in the radeon driver but the maintainer says he doesn't like such a workaround, and radeon is not the only example of mutex protected mmio.
So we should extend the mmiowb tracking system from spinlock to mutex, and maybe other locking primitives. This is not easy and error prone, so we solve it in the architectural code, by simply defining the __io_aw() hook as mmiowb(). And we no longer need to override queued_spin_unlock() so use the generic definition.
Without this, we get such an error when run 'glxgears' on weak ordering architectures such as LoongArch:

In the Linux kernel, the following vulnerability has been resolved:
netfilter: bridge: replace physindev with physinif in nf_bridge_info
An skb can be added to a neigh->arp_queue while waiting for an arp reply. Where original skb's skb->dev can be different to neigh's neigh->dev. For instance in case of bridging dnated skb from one veth to another, the skb would be added to a neigh->arp_queue of the bridge.
As skb->dev can be reset back to nf_bridge->physindev and used, and as there is no explicit mechanism that prevents this physindev from been freed under us (for instance neigh_flush_dev doesn't cleanup skbs from different device's neigh queue) we can crash on e.g. this stack:
arp_process neigh_update skb = __skb_dequeue(&neigh->arp_queue) neigh_resolve_output(..., skb) ... br_nf_dev_xmit br_nf_pre_routing_finish_bridge_slow skb->dev = nf_bridge->physindev br_handle_frame_finish
Let's use plain ifindex instead of net_device link. To peek into the original net_device we will use dev_get_by_index_rcu(). Thus either we get device and are safe to use it or we don't get it and drop skb.(CVE-2024-35839)

This is because the file has only one direct_node. After returning to -ENOSPC, reserved_blocks += ret will not be executed. As a result, the reserved_blocks at this time is still 0, which is not the real number of reserved blocks. Therefore, fsck cannot be set to repair the file.
After this patch, the fsck flag will be set to fix this problem.

ipv6: Fix infinite recursion in fib6_dump_done().
syzkaller reported infinite recursive calls of fib6_dump_done() during netlink socket destruction. [1]
From the log, syzkaller sent an AF_UNSPEC RTM_GETROUTE message, and then the response was generated. The following recvmmsg() resumed the dump for IPv6, but the first call of inet6_dump_fib() failed at kzalloc() due to the fault injection. [0]
12:01:34 executing program 3: r0 = socket$nl_route(0x10, 0x3, 0x0) sendmsg$nl_route(r0, ... snip ...) recvmmsg(r0, ... snip ...) (fail_nth: 8)
Here, fib6_dump_done() was set to nlk_sk(sk)->cb.done, and the next call of inet6_dump_fib() set it to nlk_sk(sk)->cb.args[3]. syzkaller stopped receiving the response halfway through, and finally netlink_sock_destruct() called nlk_sk(sk)->cb.done().
fib6_dump_done() calls fib6_dump_end() and nlk_sk(sk)->cb.done() if it is still not NULL. fib6_dump_end() rewrites nlk_sk(sk)->cb.done() by nlk_sk(sk)->cb.args[3], but it has the same function, not NULL, calling itself recursively and hitting the stack guard page.
To avoid the issue, let's set the destructor after kzalloc().

In the Linux kernel, the following vulnerability has been resolved:
netfilter: nf_tables: discard table flag update with pending basechain deletion
Hook unregistration is deferred to the commit phase, same occurs with hook updates triggered by the table dormant flag. When both commands are combined, this results in deleting a basechain while leaving its hook still registered in the core.(CVE-2024-35897)
In the Linux kernel, the following vulnerability has been resolved:
netfilter: nf_tables: Fix potential data-race in __nft_flowtable_type_get()
nft_unregister_flowtable_type() within nf_flow_inet_module_exit() can concurrent with __nft_flowtable_type_get() within nf_tables_newflowtable(). And thhere is not any protection when iterate over nf_tables_flowtables list in __nft_flowtable_type_get(). Therefore, there is pertential data-race of nf_tables_flowtables list entry.
Use list_for_each_entry_rcu() to iterate over nf_tables_flowtables list in __nft_flowtable_type_get(), and use rcu_read_lock() in the caller nft_flowtable_type_get() to protect the entire type query process.(CVE-2024-35898)
In the Linux kernel, the following vulnerability has been resolved:
fbmon: prevent division by zero in fb_videomode_from_videomode()
The expression htotal * vtotal can have a zero value on overflow. It is necessary to prevent division by zero like in fb_var_to_videomode().

In the Linux kernel, the following vulnerability has been resolved:
scsi: lpfc: Fix possible memory leak in lpfc_rcv_padisc()
The call to lpfc_sli4_resume_rpi() in lpfc_rcv_padisc() may return an unsuccessful status. In such cases, the elsiocb is not issued, the completion is not called, and thus the elsiocb resource is leaked.
Check return value after calling lpfc_sli4_resume_rpi() and conditionally release the elsiocb resource.(CVE-2024-35930)
In the Linux kernel, the following vulnerability has been resolved:
btrfs: handle chunk tree lookup error in btrfs_relocate_sys_chunks()
The unhandled case in btrfs_relocate_sys_chunks() loop is a corruption, as it could be caused only by two impossible conditions:
-
at first the search key is set up to look for a chunk tree item, with offset -1, this is an inexact search and the key->offset will contain the correct offset upon a successful search, a valid chunk tree item cannot have an offset -1
-
after first successful search, the found_key corresponds to a chunk item, the offset is decremented by 1 before the next loop, it's impossible to find a chunk item there due to alignment and size constraints(CVE-2024-35936)
In the Linux kernel, the following vulnerability has been resolved:
pstore/zone: Add a null pointer check to the psz_kmsg_read
kasprintf() returns a pointer to dynamically allocated memory which can be NULL upon failure. Ensure the allocation was successful by checking the pointer validity.(CVE-2024-35940)

ACPI: CPPC: Use access_width over bit_width for system memory accesses
To align with ACPI 6.3+, since bit_width can be any 8-bit value, it cannot be depended on to be always on a clean 8b boundary. This was uncovered on the Cobalt 100 platform.

Instead, use access_width to determine the size and use the offset and width to shift and mask the bits to read/write out. Make sure to add a check for system memory since pcc redefines the access_width to subspace id.
If access_width is not set, then fall back to using bit_width.

In the Linux kernel, the following vulnerability has been resolved:
HID: i2c-hid: remove I2C_HID_READ_PENDING flag to prevent lock-up
The flag I2C_HID_READ_PENDING is used to serialize I2C operations. However, this is not necessary, because I2C core already has its own locking for that.
More importantly, this flag can cause a lock-up: if the flag is set in i2c_hid_xfer() and an interrupt happens, the interrupt handler (i2c_hid_irq) will check this flag and return immediately without doing anything, then the interrupt handler will be invoked again in an infinite loop.
Since interrupt handler is an RT task, it takes over the CPU and the flag-clearing task never gets scheduled, thus we have a lock-up.
Delete this unnecessary flag.(CVE-2024-35997)

Fix by returning if the lists are empty as there is nothing to migrate in this case.

Due to the lengthy analysis of\nthe pcrypt_aead01 function call, I\u0026apos;ll describe the problem scenario\nusing a simplified model:\r\n\r\nSuppose there\u0026apos;s a user of padata named `user_function` that adheres to\nthe padata requirement of calling `padata_free_shell` after `serial()`\nhas been invoked, as demonstrated in the following code:\r\n\r\n```c\nstruct request {\n struct padata_priv padata;\n struct completion *done;\n};\r\n\r\nvoid parallel(struct padata_priv *padata) {\n do_something();\n}\r\n\r\nvoid serial(struct padata_priv *padata) {\n struct request *request = container_of(padata,\n \t\t\t\tstruct request,\n\t\t\t\tpadata);\n complete(request-\u0026gt;done);\n}\r\n\r\nvoid user_function() {\n DECLARE_COMPLETION(done)\n padata-\u0026gt;parallel = parallel;\n padata-\u0026gt;serial = serial;\n padata_do_parallel();\n wait_for_completion(\u0026amp;done);\n padata_free_shell();\n}\n```\r\n\r\nIn the corresponding padata.c file, there\u0026apos;s the following code:\r\n\r\n```c\nstatic void padata_serial_worker(struct work_struct *serial_work) {\n ...\n cnt = 0;\r\n\r\n while (!list_empty(\u0026amp;local_list)) {\n ...\n padata-\u0026gt;serial(padata);\n cnt++;\n }\r\n\r\n local_bh_enable();\r\n\r\n if (refcount_sub_and_test(cnt, \u0026amp;pd-\u0026gt;refcnt))\n padata_free_pd(pd);\n}\n```\r\n\r\nBecause of the high system load and the accumulation of unexecuted\nsoftirq at this moment, `local_bh_enable()` in padata takes longer\nto execute than usual. Subsequently, when accessing `pd-\u0026gt;refcnt`,\n`pd` has already been released by `padata_free_shell()`, resulting\nin a UAF issue with `pd-\u0026gt;refcnt`.\r\n\r\nThe fix is straightforward: add `refcount_dec_and_test` before calling\n`padata_free_pd` in `padata_free_shell`.(CVE-2023-52854)\r\n\r\nIn the Linux kernel, the following vulnerability has been resolved:\r\n\r\nclk: mediatek: clk-mt7629: Add check for mtk_alloc_clk_data\r\n\r\nAdd the check for the return value of mtk_alloc_clk_data() in order to\navoid NULL pointer dereference.(CVE-2023-52858)\r\n\r\nIn the Linux kernel, the following vulnerability has been resolved:\r\n\r\nhwmon: (axi-fan-control) Fix possible NULL pointer dereference\r\n\r\naxi_fan_control_irq_handler(), dependent on the private\naxi_fan_control_data structure, might be called before the hwmon\ndevice is registered.

Trying to flush a bogus workqueue entry rightly makes\n__flush_work() complain (kudos to whoever added that sanity check).\r\n\r\nNote, commit 5f6de5cbebee (\u0026quot;KVM: Prevent module exit until al\n---truncated---(CVE-2024-26976)\r\n\r\nIn the Linux kernel, the following vulnerability has been resolved:\r\n\r\nSquashfs: check the inode number is not the invalid value of zero\r\n\r\nSyskiller has produced an out of bounds access in fill_meta_index().\r\n\r\nThat out of bounds access is ultimately caused because the inode\nhas an inode number with the invalid value of zero, which was not checked.\r\n\r\nThe reason this causes the out of bounds access is due to following\nsequence of events:\r\n\r\n1. Fill_meta_index() is called to allocate (via empty_meta_index())\n and fill a metadata index. It however suffers a data read error\n and aborts, invalidating the newly returned empty metadata index.\n It does this by setting the inode number of the index to zero,\n which means unused (zero is not a valid inode number).\r\n\r\n2. When fill_meta_index() is subsequently called again on another\n read operation, locate_meta_index() returns the previous index\n because it matches the inode number of 0. Because this index\n has been returned it is expected to have been filled, and because\n it hasn\u0026apos;t been, an out of bounds access is performed.\r\n\r\nThis patch adds a sanity check which checks that the inode number\nis not zero when the inode is created and returns -EINVAL if it is.\r\n\r\n[phillip@squashfs.org.uk: whitespace fix]\n Link: https://lkml.kernel.org/r/20240409204723.446925-1-phillip@squashfs.org.uk(CVE-2024-26982)\r\n\r\nIn the Linux kernel, the following vulnerability has been resolved:\r\n\r\nfs: sysfs: Fix reference leak in sysfs_break_active_protection()\r\n\r\nThe sysfs_break_active_protection() routine has an obvious reference\nleak in its error path.

However, pairing each mmiowb() removal in this patch with\nthe corresponding call to spin_unlock() is not at all trivial, so there\nis a small chance that this change may regress any drivers incorrectly\nrelying on mmiowb() to order MMIO writes between CPUs using lock-free\nsynchronisation.\u0026quot;\r\n\r\nThe mmio in radeon_ring_commit() is protected by a mutex rather than a\nspinlock, but in the mutex fastpath it behaves similar to spinlock.

In the Linux kernel, the following vulnerability has been resolved:
mISDN: fix possible use-after-free in HFC_cleanup()
This module's remove path calls del_timer(). However, that function does not wait until the timer handler finishes. This means that the timer handler may still be running after the driver's remove function has finished, which would result in a use-after-free.
Fix by calling del_timer_sync(), which makes sure the timer handler has finished, and unable to re-schedule itself.(CVE-2021-47356)
In the Linux kernel, the following vulnerability has been resolved:
net: stmmac: Disable Tx queues when reconfiguring the interface
The Tx queues were not disabled in situations where the driver needed to stop the interface to apply a new configuration. This could result in a kernel panic when doing any of the 3 following actions: * reconfiguring the number of queues (ethtool -L) * reconfiguring the size of the ring buffers (ethtool -G) * installing/removing an XDP program (ip l set dev ethX xdp)
Prevent the panic by making sure netif_tx_disable is called when stopping an interface.
Without this patch, the following kernel panic can be observed when doing any of the actions above:
Unable to handle kernel paging request at virtual address ffff80001238d040 [....] Call trace: dwmac4_set_addr+0x8/0x10 dev_hard_start_xmit+0xe4/0x1ac sch_direct_xmit+0xe8/0x39c __dev_queue_xmit+0x3ec/0xaf0 dev_queue_xmit+0x14/0x20 [...] [ end trace 0000000000000002 ]---(CVE-2021-47558)
In the Linux kernel, the following vulnerability has been resolved:
ice: Fix crash by keep old cfg when update TCs more than queues
There are problems if allocated queues less than Traffic Classes.
Commit a632b2a4c920 ("ice: ethtool: Prohibit improper channel config for DCB") already disallow setting less queues than TCs.
Another case is if we first set less queues, and later update more TCs config due to LLDP, ice_vsi_cfg_tc() will failed but left dirty num_txq/rxq and tc_cfg in vsi, that will cause invalid pointer access.

nilfs2: fix underflow in second superblock position calculations
Macro NILFS_SB2_OFFSET_BYTES, which computes the position of the second superblock, underflows when the argument device size is less than 4096 bytes. Therefore, when using this macro, it is necessary to check in advance that the device size is not less than a lower limit, or at least that underflow does not occur.
The current nilfs2 implementation lacks this check, causing out-of-bound block access when mounting devices smaller than 4096 bytes:
I/O error, dev loop0, sector 36028797018963960 op 0x0:(READ) flags 0x0 phys_seg 1 prio class 2 NILFS (loop0): unable to read secondary superblock (blocksize = 1024)
In addition, when trying to resize the filesystem to a size below 4096 bytes, this underflow occurs in nilfs_resize_fs(), passing a huge number of segments to nilfs_sufile_resize(), corrupting parameters such as the number of segments in superblocks. This causes excessive loop iterations in nilfs_sufile_resize() during a subsequent resize ioctl, causing semaphore ns_segctor_sem to block for a long time and hang the writer thread:

IB/IPoIB: Fix legacy IPoIB due to wrong number of queues
The cited commit creates child PKEY interfaces over netlink will multiple tx and rx queues, but some devices doesn't support more than 1 tx and 1 rx queues. This causes to a crash when traffic is sent over the PKEY interface due to the parent having a single queue but the child having multiple queues.
This patch fixes the number of queues to 1 for legacy IPoIB at the earliest possible point in time.

net/smc: avoid data corruption caused by decline
We found a data corruption issue during testing of SMC-R on Redis applications.
The benchmark has a low probability of reporting a strange error as shown below.
"Error: Protocol error, got "\xe2" as reply type byte"
Finally, we found that the retrieved error data was as follows:
0xE2 0xD4 0xC3 0xD9 0x04 0x00 0x2C 0x20 0xA6 0x56 0x00 0x16 0x3E 0x0C 0xCB 0x04 0x02 0x01 0x00 0x00 0x20 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0xE2
It is quite obvious that this is a SMC DECLINE message, which means that the applications received SMC protocol message. We found that this was caused by the following situations:
client server ¦ clc proposal -------------> ¦ clc accept <------------- ¦ clc confirm -------------> wait llc confirm send llc confirm ¦failed llc confirm ¦ x------ (after 2s)timeout wait llc confirm rsp
wait decline
(after 1s) timeout (after 2s) timeout ¦ decline --------------> ¦ decline <--------------
As a result, a decline message was sent in the implementation, and this message was read from TCP by the already-fallback connection.
This patch double the client timeout as 2x of the server value, With this simple change, the Decline messages should never cross or collide (during Confirm link timeout).
This issue requires an immediate solution, since the protocol updates involve a more long-term solution.(CVE-2023-52775)
In the Linux kernel, the following vulnerability has been resolved:
ipvlan: add ipvlan_route_v6_outbound() helper
Inspired by syzbot reports using a stack of multiple ipvlan devices.
Reduce stack size needed in ipvlan_process_v6_outbound() by moving the flowi6 struct used for the route lookup in an non inlined helper. ipvlan_route_v6_outbound() needs 120 bytes on the stack, immediately reclaimed.
Also make sure ipvlan_process_v4_outbound() is not inlined.
We might also have to lower MAX_NEST_DEV, because only syzbot uses setups with more than four stacked devices.

SUNRPC: Fix RPC client cleaned up the freed pipefs dentries
RPC client pipefs dentries cleanup is in separated rpc_remove_pipedir() workqueue,which takes care about pipefs superblock locking. In some special scenarios, when kernel frees the pipefs sb of the current client and immediately alloctes a new pipefs sb, rpc_remove_pipedir function would misjudge the existence of pipefs sb which is not the one it used to hold. As a result, the rpc_remove_pipedir would clean the released freed pipefs dentries.
To fix this issue, rpc_remove_pipedir should check whether the current pipefs sb is consistent with the original pipefs sb.

Since v6.6 the call page_pool_release_page() were removed (in commit 535b9c61bdef ("net: page_pool: hide page_pool_release_page()") and remaining callers converted (in commit 6bfef2ec0172 ("Merge branch 'net-page_pool-remove-page_pool_release_page'")).

In the Linux kernel, the following vulnerability has been resolved:
phonet/pep: fix racy skb_queue_empty() use
The receive queues are protected by their respective spin-lock, not the socket lock. This could lead to skb_peek() unexpectedly returning NULL or a pointer to an already dequeued socket buffer.(CVE-2024-27402)
In the Linux kernel, the following vulnerability has been resolved:
netfilter: bridge: confirm multicast packets before passing them up the stack
conntrack nf_confirm logic cannot handle cloned skbs referencing the same nf_conn entry, which will happen for multicast (broadcast) frames on bridges.
Example: macvlan0 | br0 / \ ethX ethY
ethX (or Y) receives a L2 multicast or broadcast packet containing an IP packet, flow is not yet in conntrack table.
- skb passes through bridge and fake-ip (br_netfilter)Prerouting. -> skb->_nfct now references a unconfirmed entry
- skb is broad/mcast packet. bridge now passes clones out on each bridge interface.
- skb gets passed up the stack.
-
In macvlan case, macvlan driver retains clone(s) of the mcast skb and schedules a work queue to send them out on the lower devices.
The clone skb->_nfct is not a copy, it is the same entry as the original skb. The macvlan rx handler then returns RX_HANDLER_PASS. 5. Normal conntrack hooks (in NF_INET_LOCAL_IN) confirm the orig skb.
The Macvlan broadcast worker and normal confirm path will race.
This race will not happen if step 2 already confirmed a clone. In that case later steps perform skb_clone() with skb->_nfct already confirmed (in hash table). This works fine.
But such confirmation won't happen when eb/ip/nftables rules dropped the packets before they reached the nf_confirm step in postrouting.
Pablo points out that nf_conntrack_bridge doesn't allow use of stateful nat, so we can safely discard the nf_conn entry and let inet call conntrack again.
This doesn't work for bridge netfilter: skb could have a nat transformation. Also bridge nf prevents re-invocation of inet prerouting via 'sabotage_in' hook.
Work around this problem by explicit confirmation of the entry at LOCAL_IN time, before upper layer has a chance to clone the unconfirmed entry.
The downside is that this disables NAT and conntrack helpers.
Alternative fix would be to add locking to all code parts that deal with unconfirmed packets, but even if that could be done in a sane way this opens up other problems, for example:
-m physdev --physdev-out eth0 -j SNAT --snat-to 1.2.3.4 -m physdev --physdev-out eth1 -j SNAT --snat-to 1.2.3.5
For multicast case, only one of such conflicting mappings will be created, conntrack only handles 1:1 NAT mappings.
Users should set create a setup that explicitly marks such traffic NOTRACK (conntrack bypass) to avoid this, but we cannot auto-bypass them, ruleset might have accept rules for untracked traffic already, so user-visible behaviour would change.(CVE-2024-27415)
In the Linux kernel, the following vulnerability has been resolved:
usb: typec: altmodes/displayport: create sysfs nodes as driver's default device attribute group
The DisplayPort driver's sysfs nodes may be present to the userspace before typec_altmode_set_drvdata() completes in dp_altmode_probe. This means that a sysfs read can trigger a NULL pointer error by deferencing dp->hpd in hpd_show or dp->lock in pin_assignment_show, as dev_get_drvdata() returns NULL in those cases.
Remove manual sysfs node creation in favor of adding attribute group as default for devices bound to the driver. The ATTRIBUTE_GROUPS() macro is not used here otherwise the path to the sysfs nodes is no longer compliant with the ABI.(CVE-2024-35790)
In the Linux kernel, the following vulnerability has been resolved:
PCI/PM: Drain runtime-idle callbacks before driver removal
A race condition between the .runtime_idle() callback and the .remove() callback in the rtsx_pcr PCI driver leads to a kernel crash due to an unhandled page fault [1].
The problem is that rtsx_pci_runtime_idle() is not expected to be running after pm_runtime_get_sync() has been called, but the latter doesn't really guarantee that. It only guarantees that the suspend and resume callbacks will not be running when it returns.
However, if a .runtime_idle() callback is already running when pm_runtime_get_sync() is called, the latter will notice that the runtime PM status of the device is RPM_ACTIVE and it will return right away without waiting for the former to complete. In fact, it cannot wait for .runtime_idle() to complete because it may be called from that callback (it arguably does not make much sense to do that, but it is not strictly prohibited).
Thus in general, whoever is providing a .runtime_idle() callback needs to protect it from running in parallel with whatever code runs after pm_runtime_get_sync(). [Note that .runtime_idle() will not start after pm_runtime_get_sync() has returned, but it may continue running then if it has started earlier.]
One way to address that race condition is to call pm_runtime_barrier() after pm_runtime_get_sync() (not before it, because a nonzero value of the runtime PM usage counter is necessary to prevent runtime PM callbacks from being invoked) to wait for the .runtime_idle() callback to complete should it be running at that point. A suitable place for doing that is in pci_device_remove() which calls pm_runtime_get_sync() before removing the driver, so it may as well call pm_runtime_barrier() subsequently, which will prevent the race in question from occurring, not just in the rtsx_pcr driver, but in any PCI drivers providing .runtime_idle() callbacks.(CVE-2024-35809)
In the Linux kernel, the following vulnerability has been resolved:
mlxsw: spectrum_acl_tcam: Fix memory leak during rehash
The rehash delayed work migrates filters from one region to another. This is done by iterating over all chunks (all the filters with the same priority) in the region and in each chunk iterating over all the filters.
If the migration fails, the code tries to migrate the filters back to the old region. However, the rollback itself can also fail in which case another migration will be erroneously performed. Besides the fact that this ping pong is not a very good idea, it also creates a problem.
Each virtual chunk references two chunks: The currently used one ('vchunk->chunk') and a backup ('vchunk->chunk2'). During migration the first holds the chunk we want to migrate filters to and the second holds the chunk we are migrating filters from.
The code currently assumes - but does not verify - that the backup chunk does not exist (NULL) if the currently used chunk does not reference the target region. This assumption breaks when we are trying to rollback a rollback, resulting in the backup chunk being overwritten and leaked [1].
Fix by not rolling back a failed rollback and add a warning to avoid future cases.

mlxsw: spectrum_acl_tcam: Fix possible use-after-free during rehash
The rehash delayed work migrates filters from one region to another according to the number of available credits.
The migrated from region is destroyed at the end of the work if the number of credits is non-negative as the assumption is that this is indicative of migration being complete. This assumption is incorrect as a non-negative number of credits can also be the result of a failed migration.
The destruction of a region that still has filters referencing it can result in a use-after-free [1].
Fix by not destroying the region if migration failed.

mlxsw: spectrum_acl_tcam: Fix possible use-after-free during activity update
The rule activity update delayed work periodically traverses the list of configured rules and queries their activity from the device.
As part of this task it accesses the entry pointed by 'ventry->entry', but this entry can be changed concurrently by the rehash delayed work, leading to a use-after-free [1].
Fix by closing the race and perform the activity query under the 'vregion->lock' mutex.

In the Linux kernel, the following vulnerability has been resolved:
ipv6: Fix infinite recursion in fib6_dump_done().
syzkaller reported infinite recursive calls of fib6_dump_done() during netlink socket destruction. [1]
From the log, syzkaller sent an AF_UNSPEC RTM_GETROUTE message, and then the response was generated. The following recvmmsg() resumed the dump for IPv6, but the first call of inet6_dump_fib() failed at kzalloc() due to the fault injection. [0]
12:01:34 executing program 3: r0 = socket$nl_route(0x10, 0x3, 0x0) sendmsg$nl_route(r0, ... snip ...) recvmmsg(r0, ... snip ...) (fail_nth: 8)
Here, fib6_dump_done() was set to nlk_sk(sk)->cb.done, and the next call of inet6_dump_fib() set it to nlk_sk(sk)->cb.args[3]. syzkaller stopped receiving the response halfway through, and finally netlink_sock_destruct() called nlk_sk(sk)->cb.done().
fib6_dump_done() calls fib6_dump_end() and nlk_sk(sk)->cb.done() if it is still not NULL. fib6_dump_end() rewrites nlk_sk(sk)->cb.done() by nlk_sk(sk)->cb.args[3], but it has the same function, not NULL, calling itself recursively and hitting the stack guard page.
To avoid the issue, let's set the destructor after kzalloc().

In the Linux kernel, the following vulnerability has been resolved:
bpf, sockmap: Prevent lock inversion deadlock in map delete elem
syzkaller started using corpuses where a BPF tracing program deletes elements from a sockmap/sockhash map. Because BPF tracing programs can be invoked from any interrupt context, locks taken during a map_delete_elem operation must be hardirq-safe. Otherwise a deadlock due to lock inversion is possible, as reported by lockdep:
CPU0 CPU1
---- ----
lock(&htab->buckets[i].lock); local_irq_disable(); lock(&host->lock); lock(&htab->buckets[i].lock); <Interrupt> lock(&host->lock);
Locks in sockmap are hardirq-unsafe by design. We expects elements to be deleted from sockmap/sockhash only in task (normal) context with interrupts enabled, or in softirq context.
Detect when map_delete_elem operation is invoked from a context which is not hardirq-unsafe, that is interrupts are disabled, and bail out with an error.
Note that map updates are not affected by this issue. BPF verifier does not allow updating sockmap/sockhash from a BPF tracing program today.(CVE-2024-35895)

In the Linux kernel, the following vulnerability has been resolved:
bpf: Protect against int overflow for stack access size
This patch re-introduces protection against the size of access to stack memory being negative; the access size can appear negative as a result of overflowing its signed int representation. This should not actually happen, as there are other protections along the way, but we should protect against it anyway. One code path was missing such protections (fixed in the previous patch in the series), causing out-of-bounds array accesses in check_stack_range_initialized(). This patch causes the verification of a program with such a non-sensical access size to fail.
This check used to exist in a more indirect way, but was inadvertendly removed in a833a17aeac7.(CVE-2024-35905)
In the Linux kernel, the following vulnerability has been resolved:
nfc: nci: Fix uninit-value in nci_dev_up and nci_ntf_packet
syzbot reported the following uninit-value access issue [1][2]:
nci_rx_work() parses and processes received packet. When the payload length is zero, each message type handler reads uninitialized payload and KMSAN detects this issue. The receipt of a packet with a zero-size payload is considered unexpected, and therefore, such packets should be silently discarded.
This patch resolved this issue by checking payload size before calling each message type handler codes.(CVE-2024-35915)
In the Linux kernel, the following vulnerability has been resolved:
usb: typec: ucsi: Limit read size on v1.2
Between UCSI 1.2 and UCSI 2.0, the size of the MESSAGE_IN region was increased from 16 to 256. In order to avoid overflowing reads for older systems, add a mechanism to use the read UCSI version to truncate read sizes on UCSI v1.2.(CVE-2024-35924)
In the Linux kernel, the following vulnerability has been resolved:
block: prevent division by zero in blk_rq_stat_sum()
The expression dst->nr_samples + src->nr_samples may have zero value on overflow. It is necessary to add a check to avoid division by zero.
Found by Linux Verification Center (linuxtesting.org) with Svace.(CVE-2024-35925)

In the Linux kernel, the following vulnerability has been resolved:
geneve: fix header validation in geneve[6]_xmit_skb
syzbot is able to trigger an uninit-value in geneve_xmit() [1]
Problem : While most ip tunnel helpers (like ip_tunnel_get_dsfield()) uses skb_protocol(skb, true), pskb_inet_may_pull() is only using skb->protocol.
If anything else than ETH_P_IPV6 or ETH_P_IP is found in skb->protocol, pskb_inet_may_pull() does nothing at all.
If a vlan tag was provided by the caller (af_packet in the syzbot case), the network header might not point to the correct location, and skb linear part could be smaller than expected.
Add skb_vlan_inet_prepare() to perform a complete mac validation.
Use this in geneve for the moment, I suspect we need to adopt this more broadly.
v4 - Jakub reported v3 broke l2_tos_ttl_inherit.sh selftest - Only call __vlan_get_protocol() for vlan types.
v2,v3 - Addressed Sabrina comments on v1 and v2

In the Linux kernel, the following vulnerability has been resolved:
rtnetlink: Correct nested IFLA_VF_VLAN_LIST attribute validation
Each attribute inside a nested IFLA_VF_VLAN_LIST is assumed to be a struct ifla_vf_vlan_info so the size of such attribute needs to be at least of sizeof(struct ifla_vf_vlan_info) which is 14 bytes. The current size validation in do_setvfinfo is against NLA_HDRLEN (4 bytes) which is less than sizeof(struct ifla_vf_vlan_info) so this validation is not enough and a too small attribute might be cast to a struct ifla_vf_vlan_info, this might result in an out of bands read access when accessing the saved (casted) entry in ivvl.(CVE-2024-36017)
In the Linux kernel, the following vulnerability has been resolved:
net: hns3: fix kernel crash when devlink reload during pf initialization
The devlink reload process will access the hardware resources, but the register operation is done before the hardware is initialized. So, processing the devlink reload during initialization may lead to kernel crash. This patch fixes this by taking devl_lock during initialization.(CVE-2024-36021)
In the Linux kernel, the following vulnerability has been resolved:
mmc: sdhci-msm: pervent access to suspended controller
Generic sdhci code registers LED device and uses host->runtime_suspended flag to protect access to it. The sdhci-msm driver doesn't set this flag, which causes a crash when LED is accessed while controller is runtime suspended. Fix this by setting the flag correctly.(CVE-2024-36029)
In the Linux kernel, the following vulnerability has been resolved:
net: fix out-of-bounds access in ops_init
net_alloc_generic is called by net_alloc, which is called without any locking. It reads max_gen_ptrs, which is changed under pernet_ops_rwsem. It is read twice, first to allocate an array, then to set s.len, which is later used to limit the bounds of the array access.
It is possible that the array is allocated and another thread is registering a new pernet ops, increments max_gen_ptrs, which is then used to set s.len with a larger than allocated length for the variable array.
Fix it by reading max_gen_ptrs only once in net_alloc_generic. If max_gen_ptrs is later incremented, it will be caught in net_assign_generic.(CVE-2024-36883)

When fallback to TCP happens early on a client socket, snd_nxt is not yet initialized and any incoming ack will copy such value into snd_una. If the mptcp worker (dumbly) tries mptcp-level re-injection after such ack, that would unconditionally trigger a send buffer cleanup using 'bad' snd_una values.
We could easily disable re-injection for fallback sockets, but such dumb behavior already helped catching a few subtle issues and a very low to zero impact in practice.
Instead address the issue always initializing snd_nxt (and write_seq, for consistency) at connect time.(CVE-2024-36889)
In the Linux kernel, the following vulnerability has been resolved:
gpiolib: cdev: fix uninitialised kfifo
If a line is requested with debounce, and that results in debouncing in software, and the line is subsequently reconfigured to enable edge detection then the allocation of the kfifo to contain edge events is overlooked. This results in events being written to and read from an uninitialised kfifo. Read events are returned to userspace.
Initialise the kfifo in the case where the software debounce is already active.(CVE-2024-36898)
In the Linux kernel, the following vulnerability has been resolved:
gpiolib: cdev: Fix use after free in lineinfo_changed_notify
The use-after-free issue occurs as follows: when the GPIO chip device file is being closed by invoking gpio_chrdev_release(), watched_lines is freed by bitmap_free(), but the unregistration of lineinfo_changed_nb notifier chain failed due to waiting write rwsem. Additionally, one of the GPIO chip's lines is also in the release process and holds the notifier chain's read rwsem. Consequently, a race condition leads to the use-after-free of watched_lines.
Here is the typical stack when issue happened:
[free] gpio_chrdev_release() --> bitmap_free(cdev->watched_lines) <-- freed --> blocking_notifier_chain_unregister() --> down_write(&nh->rwsem) <-- waiting rwsem --> __down_write_common() --> rwsem_down_write_slowpath() --> schedule_preempt_disabled() --> schedule()
[use] st54spi_gpio_dev_release() --> gpio_free() --> gpiod_free() --> gpiod_free_commit() --> gpiod_line_state_notify() --> blocking_notifier_call_chain() --> down_read(&nh->rwsem); <-- held rwsem --> notifier_call_chain() --> lineinfo_changed_notify() --> test_bit(xxxx, cdev->watched_lines) <-- use after free
The side effect of the use-after-free issue is that a GPIO line event is being generated for userspace where it shouldn't. However, since the chrdev is being closed, userspace won't have the chance to read that event anyway.
To fix the issue, call the bitmap_free() function after the unregistration of lineinfo_changed_nb notifier chain.(CVE-2024-36899)
In the Linux kernel, the following vulnerability has been resolved:

In the Linux kernel, the following vulnerability has been resolved:
tcp: defer shutdown(SEND_SHUTDOWN) for TCP_SYN_RECV sockets
TCP_SYN_RECV state is really special, it is only used by cross-syn connections, mostly used by fuzzers.
In the following crash [1], syzbot managed to trigger a divide by zero in tcp_rcv_space_adjust()
A socket makes the following state transitions, without ever calling tcp_init_transfer(), meaning tcp_init_buffer_space() is also not called.
TCP_CLOSE
connect() TCP_SYN_SENT TCP_SYN_RECV shutdown() -> tcp_shutdown(sk, SEND_SHUTDOWN) TCP_FIN_WAIT1
To fix this issue, change tcp_shutdown() to not perform a TCP_SYN_RECV -> TCP_FIN_WAIT1 transition, which makes no sense anyway.
When tcp_rcv_state_process() later changes socket state from TCP_SYN_RECV to TCP_ESTABLISH, then look at sk->sk_shutdown to finally enter TCP_FIN_WAIT1 state, and send a FIN packet from a sane socket state.
This means tcp_send_fin() can now be called from BH context, and must use GFP_ATOMIC allocations.

We find the root cause of this OOB is that arm does not clear stale stack poison in the case of cpuidle.
This patch refer to arch/arm64/kernel/sleep.S to resolve this issue.
From cited commit [1] that explain the problem
Functions which the compiler has instrumented for KASAN place poison on the stack shadow upon entry and remove this poison prior to returning.
In the case of cpuidle, CPUs exit the kernel a number of levels deep in C code. Any instrumented functions on this critical path will leave portions of the stack shadow poisoned.
If CPUs lose context and return to the kernel via a cold path, we restore a prior context saved in __cpu_suspend_enter are forgotten, and we never remove the poison they placed in the stack shadow area by functions calls between this and the actual exit of the kernel.
Thus, (depending on stackframe layout) subsequent calls to instrumented functions may hit this stale poison, resulting in (spurious) KASAN splats to the console.
To avoid this, clear any stale poison from the idle thread for a CPU prior to bringing a CPU online.
From cited commit [2]
Extend to check for CONFIG_KASAN_STACK
[1] commit 0d97e6d8024c ("arm64: kasan: clear stale stack poison") [2] commit d56a9ef84bd0 ("kasan, arm64: unpoison stack only with CONFIG_KASAN_STACK")(CVE-2024-36906)
In the Linux kernel, the following vulnerability has been resolved:
blk-iocost: do not WARN if iocg was already offlined
In iocg_pay_debt(), warn is triggered if 'active_list' is empty, which is intended to confirm iocg is active when it has debt. However, warn can be triggered during a blkcg or disk removal, if iocg_waitq_timer_fn() is run at that time:
WARNING: CPU: 0 PID: 2344971 at block/blk-iocost.c:1402 iocg_pay_debt+0x14c/0x190 Call trace: iocg_pay_debt+0x14c/0x190 iocg_kick_waitq+0x438/0x4c0 iocg_waitq_timer_fn+0xd8/0x130 __run_hrtimer+0x144/0x45c __hrtimer_run_queues+0x16c/0x244 hrtimer_interrupt+0x2cc/0x7b0
The warn in this situation is meaningless. Since this iocg is being removed, the state of the 'active_list' is irrelevant, and 'waitq_timer' is canceled after removing 'active_list' in ioc_pd_free(), which ensures iocg is freed after iocg_waitq_timer_fn() returns.
Therefore, add the check if iocg was already offlined to avoid warn when removing a blkcg or disk.(CVE-2024-36908)
In the Linux kernel, the following vulnerability has been resolved:
scsi: lpfc: Release hbalock before calling lpfc_worker_wake_up()
lpfc_worker_wake_up() calls the lpfc_work_done() routine, which takes the hbalock. Thus, lpfc_worker_wake_up() should not be called while holding the hbalock to avoid potential deadlock.(CVE-2024-36924)
In the Linux kernel, the following vulnerability has been resolved:
net: core: reject skb_copy(_expand) for fraglist GSO skbs
SKB_GSO_FRAGLIST skbs must not be linearized, otherwise they become invalid. Return NULL if such an skb is passed to skb_copy or skb_copy_expand, in order to prevent a crash on a potential later call to skb_gso_segment.(CVE-2024-36929)
In the Linux kernel, the following vulnerability has been resolved:
amd/amdkfd: sync all devices to wait all processes being evicted
If there are more than one device doing reset in parallel, the first device will call kfd_suspend_all_processes() to evict all processes on all devices, this call takes time to finish. other device will start reset and recover without waiting. if the process has not been evicted before doing recover, it will be restored, then caused page fault.(CVE-2024-36949)
In the Linux kernel, the following vulnerability has been resolved:
octeontx2-af: avoid off-by-one read from userspace
We try to access count + 1 byte from userspace with memdup_user(buffer, count + 1). However, the userspace only provides buffer of count bytes and only these count bytes are verified to be okay to access. To ensure the copied buffer is NUL terminated, we use memdup_user_nul instead.(CVE-2024-36957)
In the Linux kernel, the following vulnerability has been resolved:
fs/9p: only translate RWX permissions for plain 9P2000
Garbage in plain 9P2000's perm bits is allowed through, which causes it to be able to set (among others) the suid bit. This was presumably not the intent since the unix extended bits are handled explicitly and conditionally on .u.(CVE-2024-36964)

In macvlan case, macvlan driver retains clone(s) of the mcast skb\n and schedules a work queue to send them out on the lower devices.\r\n\r\n The clone skb-\u0026gt;_nfct is not a copy, it is the same entry as the\n original skb.

Also bridge nf prevents re-invocation of inet prerouting\nvia \u0026apos;sabotage_in\u0026apos; hook.\r\n\r\nWork around this problem by explicit confirmation of the entry at LOCAL_IN\ntime, before upper layer has a chance to clone the unconfirmed entry.\r\n\r\nThe downside is that this disables NAT and conntrack helpers.\r\n\r\nAlternative fix would be to add locking to all code parts that deal with\nunconfirmed packets, but even if that could be done in a sane way this\nopens up other problems, for example:\r\n\r\n-m physdev --physdev-out eth0 -j SNAT --snat-to 1.2.3.4\n-m physdev --physdev-out eth1 -j SNAT --snat-to 1.2.3.5\r\n\r\nFor multicast case, only one of such conflicting mappings will be\ncreated, conntrack only handles 1:1 NAT mappings.\r\n\r\nUsers should set create a setup that explicitly marks such traffic\nNOTRACK (conntrack bypass) to avoid this, but we cannot auto-bypass\nthem, ruleset might have accept rules for untracked traffic already,\nso user-visible behaviour would change.(CVE-2024-27415)\r\n\r\nIn the Linux kernel, the following vulnerability has been resolved:\r\n\r\nusb: typec: altmodes/displayport: create sysfs nodes as driver\u0026apos;s default device attribute group\r\n\r\nThe DisplayPort driver\u0026apos;s sysfs nodes may be present to the userspace before\ntypec_altmode_set_drvdata() completes in dp_altmode_probe.

The ATTRIBUTE_GROUPS() macro is\nnot used here otherwise the path to the sysfs nodes is no longer compliant\nwith the ABI.(CVE-2024-35790)\r\n\r\nIn the Linux kernel, the following vulnerability has been resolved:\r\n\r\nPCI/PM: Drain runtime-idle callbacks before driver removal\r\n\r\nA race condition between the .runtime_idle() callback and the .remove()\ncallback in the rtsx_pcr PCI driver leads to a kernel crash due to an\nunhandled page fault [1].\r\n\r\nThe problem is that rtsx_pci_runtime_idle() is not expected to be running\nafter pm_runtime_get_sync() has been called, but the latter doesn\u0026apos;t really\nguarantee that. It only guarantees that the suspend and resume callbacks\nwill not be running when it returns.\r\n\r\nHowever, if a .runtime_idle() callback is already running when\npm_runtime_get_sync() is called, the latter will notice that the runtime PM\nstatus of the device is RPM_ACTIVE and it will return right away without\nwaiting for the former to complete. In fact, it cannot wait for\n.runtime_idle() to complete because it may be called from that callback (it\narguably does not make much sense to do that, but it is not strictly\nprohibited).\r\n\r\nThus in general, whoever is providing a .runtime_idle() callback needs\nto protect it from running in parallel with whatever code runs after\npm_runtime_get_sync(). [Note that .runtime_idle() will not start after\npm_runtime_get_sync() has returned, but it may continue running then if it\nhas started earlier.]\r\n\r\nOne way to address that race condition is to call pm_runtime_barrier()\nafter pm_runtime_get_sync() (not before it, because a nonzero value of the\nruntime PM usage counter is necessary to prevent runtime PM callbacks from\nbeing invoked) to wait for the .runtime_idle() callback to complete should\nit be running at that point. A suitable place for doing that is in\npci_device_remove() which calls pm_runtime_get_sync() before removing the\ndriver, so it may as well call pm_runtime_barrier() subsequently, which\nwill prevent the race in question from occurring, not just in the rtsx_pcr\ndriver, but in any PCI drivers providing .runtime_idle() callbacks.(CVE-2024-35809)\r\n\r\nIn the Linux kernel, the following vulnerability has been resolved:\r\n\r\nmlxsw: spectrum_acl_tcam: Fix memory leak during rehash\r\n\r\nThe rehash delayed work migrates filters from one region to another.\nThis is done by iterating over all chunks (all the filters with the same\npriority) in the region and in each chunk iterating over all the\nfilters.\r\n\r\nIf the migration fails, the code tries to migrate the filters back to\nthe old region.

Read events are returned to userspace.\r\n\r\nInitialise the kfifo in the case where the software debounce is\nalready active.(CVE-2024-36898)\r\n\r\nIn the Linux kernel, the following vulnerability has been resolved:\r\n\r\ngpiolib: cdev: Fix use after free in lineinfo_changed_notify\r\n\r\nThe use-after-free issue occurs as follows: when the GPIO chip device file\nis being closed by invoking gpio_chrdev_release(), watched_lines is freed\nby bitmap_free(), but the unregistration of lineinfo_changed_nb notifier\nchain failed due to waiting write rwsem. Additionally, one of the GPIO\nchip\u0026apos;s lines is also in the release process and holds the notifier chain\u0026apos;s\nread rwsem. Consequently, a race condition leads to the use-after-free of\nwatched_lines.\r\n\r\nHere is the typical stack when issue happened:\r\n\r\n[free]\ngpio_chrdev_release()\n --\u0026gt; bitmap_free(cdev-\u0026gt;watched_lines) \u0026lt;-- freed\n --\u0026gt; blocking_notifier_chain_unregister()\n --\u0026gt; down_write(\u0026amp;nh-\u0026gt;rwsem) \u0026lt;-- waiting rwsem\n --\u0026gt; __down_write_common()\n --\u0026gt; rwsem_down_write_slowpath()\n --\u0026gt; schedule_preempt_disabled()\n --\u0026gt; schedule()\r\n\r\n[use]\nst54spi_gpio_dev_release()\n --\u0026gt; gpio_free()\n --\u0026gt; gpiod_free()\n --\u0026gt; gpiod_free_commit()\n --\u0026gt; gpiod_line_state_notify()\n --\u0026gt; blocking_notifier_call_chain()\n --\u0026gt; down_read(\u0026amp;nh-\u0026gt;rwsem); \u0026lt;-- held rwsem\n --\u0026gt; notifier_call_chain()\n --\u0026gt; lineinfo_changed_notify()\n --\u0026gt; test_bit(xxxx, cdev-\u0026gt;watched_lines) \u0026lt;-- use after free\r\n\r\nThe side effect of the use-after-free issue is that a GPIO line event is\nbeing generated for userspace where it shouldn\u0026apos;t.

Return NULL if such an skb is passed to skb_copy or\nskb_copy_expand, in order to prevent a crash on a potential later\ncall to skb_gso_segment.(CVE-2024-36929)\r\n\r\nIn the Linux kernel, the following vulnerability has been resolved:\r\n\r\namd/amdkfd: sync all devices to wait all processes being evicted\r\n\r\nIf there are more than one device doing reset in parallel, the first\ndevice will call kfd_suspend_all_processes() to evict all processes\non all devices, this call takes time to finish. other device will\nstart reset and recover without waiting. if the process has not been\nevicted before doing recover, it will be restored, then caused page\nfault.(CVE-2024-36949)\r\n\r\nIn the Linux kernel, the following vulnerability has been resolved:\r\n\r\nocteontx2-af: avoid off-by-one read from userspace\r\n\r\nWe try to access count + 1 byte from userspace with memdup_user(buffer,\ncount + 1). However, the userspace only provides buffer of count bytes and\nonly these count bytes are verified to be okay to access. To ensure the\ncopied buffer is NUL terminated, we use memdup_user_nul instead.(CVE-2024-36957)\r\n\r\nIn the Linux kernel, the following vulnerability has been resolved:\r\n\r\nfs/9p: only translate RWX permissions for plain 9P2000\r\n\r\nGarbage in plain 9P2000\u0026apos;s perm bits is allowed through, which causes it\nto be able to set (among others) the suid bit.
