Title
audit: add missing syscalls to read class
Summary
In the Linux kernel, the following vulnerability has been resolved:
audit: add missing syscalls to read class
The "at" variant of getxattr() and listxattr() are missing from the
audit read class. Calling getxattrat() or listxattrat() on a file to
read its extended attributes will bypass audit rules such as:
-w /tmp/test -p rwa -k test_rwa
The current patch adds missing syscalls to the audit read class.

In the Linux kernel, the following vulnerability has been resolved:
tls: Fix race condition in tls_sw_cancel_work_tx()
This issue was discovered during a code audit.
After cancel_delayed_work_sync() is called from tls_sk_proto_close(),
tx_work_handler() can still be scheduled from paths such as the
Delayed ACK handler or ksoftirqd.
As a result, the tx_work_handler() worker may dereference a freed
TLS object.
The following is a simple race scenario:
cpu0 cpu1
tls_sk_proto_close()
tls_sw_cancel_work_tx()
tls_write_space()
tls_sw_write_space()
if (!test_and_set_bit(BIT_TX_SCHEDULED, &tx_ctx->tx_bitmask))
set_bit(BIT_TX_SCHEDULED, &ctx->tx_bitmask);
cancel_delayed_work_sync(&ctx->tx_work.work);
schedule_delayed_work(&tx_ctx->tx_work.work, 0);
To prevent this race condition, cancel_delayed_work_sync() is
replaced with disable_delayed_work_sync().

Title
xattr: switch to CLASS(fd)
Summary
In the Linux kernel, the following vulnerability has been resolved:
fs/xattr: missing fdput() in fremovexattr error path
In the Linux kernel, the fremovexattr() syscall calls fdget() to acquire a
file reference but returns early without calling fdput() when
strncpy_from_user() fails on the name argument. In multi-threaded processes
where fdget() takes the slow path, this permanently leaks one
file reference per call, pinning the struct file and associated kernel
objects in memory. An unprivileged local user can exploit this to cause
kernel memory exhaustion. The issue was inadvertently fixed by commit
a71874379ec8 ("xattr: switch to CLASS(fd)").
Severity ?
No CVSS data available.

romfs: check sb_set_blocksize() return value
romfs_fill_super() ignores the return value of sb_set_blocksize(), which
can fail if the requested block size is incompatible with the block
device's configuration.
This can be triggered by setting a loop device's block size larger than
PAGE_SIZE using ioctl(LOOP_SET_BLOCK_SIZE, 32768), then mounting a romfs
filesystem on that device.
When sb_set_blocksize(sb, ROMBSIZE) is called with ROMBSIZE=4096 but the
device has logical_block_size=32768, bdev_validate_blocksize() fails
because the requested size is smaller than the device's logical block
size. sb_set_blocksize() returns 0 (failure), but romfs ignores this and
continues mounting.
The superblock's block size remains at the device's logical block size
(32768). Later, when sb_bread() attempts I/O with this oversized block
size, it triggers a kernel BUG in folio_set_bh():
kernel BUG at fs/buffer.c:1582!
BUG_ON(size > PAGE_SIZE);
Fix by checking the return value of sb_set_blocksize() and failing the
mount with -EINVAL if it returns 0.

Title
platform/x86: classmate-laptop: Add missing NULL pointer checks
Summary
In the Linux kernel, the following vulnerability has been resolved:
platform/x86: classmate-laptop: Add missing NULL pointer checks
In a few places in the Classmate laptop driver, code using the accel
object may run before that object's address is stored in the driver
data of the input device using it.
For example, cmpc_accel_sensitivity_store_v4() is the "show" method
of cmpc_accel_sensitivity_attr_v4 which is added in cmpc_accel_add_v4(),
before calling dev_set_drvdata() for inputdev->dev. If the sysfs
attribute is accessed prematurely, the dev_get_drvdata(&inputdev->dev)
call in in cmpc_accel_sensitivity_store_v4() returns NULL which
leads to a NULL pointer dereference going forward.
Moreover, sysfs attributes using the input device are added before
initializing that device by cmpc_add_acpi_notify_device() and if one
of them is accessed before running that function, a NULL pointer
dereference will occur.
For example, cmpc_accel_sensitivity_attr_v4 is added before calling
cmpc_add_acpi_notify_device() and if it is read prematurely, the
dev_get_drvdata(&acpi->dev) call in cmpc_accel_sensitivity_show_v4()
returns NULL which leads to a NULL pointer dereference going forward.
Fix this by adding NULL pointer checks in all of the relevant places.

Title
fbdev: smscufx: properly copy ioctl memory to kernelspace
Summary
In the Linux kernel, the following vulnerability has been resolved:
fbdev: smscufx: properly copy ioctl memory to kernelspace
The UFX_IOCTL_REPORT_DAMAGE ioctl does not properly copy data from
userspace to kernelspace, and instead directly references the memory,
which can cause problems if invalid data is passed from userspace. Fix
this all up by correctly copying the memory before accessing it within
the kernel.

Title
f2fs: fix out-of-bounds access in sysfs attribute read/write
Summary
In the Linux kernel, the following vulnerability has been resolved:
f2fs: fix out-of-bounds access in sysfs attribute read/write
Some f2fs sysfs attributes suffer from out-of-bounds memory access and
incorrect handling of integer values whose size is not 4 bytes.
For example:
vm:~# echo 65537 > /sys/fs/f2fs/vde/carve_out
vm:~# cat /sys/fs/f2fs/vde/carve_out
65537
vm:~# echo 4294967297 > /sys/fs/f2fs/vde/atgc_age_threshold
vm:~# cat /sys/fs/f2fs/vde/atgc_age_threshold
1
carve_out maps to {struct f2fs_sb_info}->carve_out, which is a 8-bit
integer. However, the sysfs interface allows setting it to a value
larger than 255, resulting in an out-of-range update.
atgc_age_threshold maps to {struct atgc_management}->age_threshold,
which is a 64-bit integer, but its sysfs interface cannot correctly set
values larger than UINT_MAX.
The root causes are:
1. __sbi_store() treats all default values as unsigned int, which
prevents updating integers larger than 4 bytes and causes out-of-bounds
writes for integers smaller than 4 bytes.
2. f2fs_sbi_show() also assumes all default values are unsigned int,
leading to out-of-bounds reads and incorrect access to integers larger
than 4 bytes.
This patch introduces {struct f2fs_attr}->size to record the actual size
of the integer associated with each sysfs attribute. With this
information, sysfs read and write operations can correctly access and
update values according to their real data size, avoiding memory
corruption and truncation.

Title
f2fs: fix to avoid UAF in f2fs_write_end_io()
Summary
In the Linux kernel, the following vulnerability has been resolved:
f2fs: fix to avoid UAF in f2fs_write_end_io()
As syzbot reported an use-after-free issue in f2fs_write_end_io().
It is caused by below race condition:
loop device umount
- worker_thread
- loop_process_work
- do_req_filebacked
- lo_rw_aio
- lo_rw_aio_complete
- blk_mq_end_request
- blk_update_request
- f2fs_write_end_io
- dec_page_count
- folio_end_writeback
- kill_f2fs_super
- kill_block_super
- f2fs_put_super
: free(sbi)
: get_pages(, F2FS_WB_CP_DATA)
accessed sbi which is freed
In kill_f2fs_super(), we will drop all page caches of f2fs inodes before
call free(sbi), it guarantee that all folios should end its writeback, so
it should be safe to access sbi before last folio_end_writeback().
Let's relocate ckpt thread wakeup flow before folio_end_writeback() to
resolve this issue.

Title
f2fs: fix to avoid mapping wrong physical block for swapfile
Summary
In the Linux kernel, the following vulnerability has been resolved:
f2fs: fix to avoid mapping wrong physical block for swapfile
Xiaolong Guo reported a f2fs bug in bugzilla [1]
[1] https://bugzilla.kernel.org/show_bug.cgi?id=220951
Quoted:
"When using stress-ng's swap stress test on F2FS filesystem with kernel 6.6+,
the system experiences data corruption leading to either:
1 dm-verity corruption errors and device reboot
2 F2FS node corruption errors and boot hangs
The issue occurs specifically when:
1 Using F2FS filesystem (ext4 is unaffected)
2 Swapfile size is less than F2FS section size (2MB)
3 Swapfile has fragmented physical layout (multiple non-contiguous extents)
4 Kernel version is 6.6+ (6.1 is unaffected)
The root cause is in check_swap_activate() function in fs/f2fs/data.c. When the
first extent of a small swapfile (< 2MB) is not aligned to section boundaries,
the function incorrectly treats it as the last extent, failing to map
subsequent extents. This results in incorrect swap_extent creation where only
the first extent is mapped, causing subsequent swap writes to overwrite wrong
physical locations (other files' data).
Steps to Reproduce
1 Setup a device with F2FS-formatted userdata partition
2 Compile stress-ng from https://github.com/ColinIanKing/stress-ng
3 Run swap stress test: (Android devices)
adb shell "cd /data/stressng; ./stress-ng-64 --metrics-brief --timeout 60
--swap 0"
Log:
1 Ftrace shows in kernel 6.6, only first extent is mapped during second
f2fs_map_blocks call in check_swap_activate():
stress-ng-swap-8990: f2fs_map_blocks: ino=11002, file offset=0, start
blkaddr=0x43143, len=0x1
(Only 4KB mapped, not the full swapfile)
2 in kernel 6.1, both extents are correctly mapped:
stress-ng-swap-5966: f2fs_map_blocks: ino=28011, file offset=0, start
blkaddr=0x13cd4, len=0x1
stress-ng-swap-5966: f2fs_map_blocks: ino=28011, file offset=1, start
blkaddr=0x60c84b, len=0xff
The problematic code is in check_swap_activate():
if ((pblock - SM_I(sbi)->main_blkaddr) % blks_per_sec ||
nr_pblocks % blks_per_sec ||
!f2fs_valid_pinned_area(sbi, pblock)) {
bool last_extent = false;
not_aligned++;
nr_pblocks = roundup(nr_pblocks, blks_per_sec);
if (cur_lblock + nr_pblocks > sis->max)
nr_pblocks -= blks_per_sec;
/* this extent is last one */
if (!nr_pblocks) {
nr_pblocks = last_lblock - cur_lblock;
last_extent = true;
}
ret = f2fs_migrate_blocks(inode, cur_lblock, nr_pblocks);
if (ret) {
if (ret == -ENOENT)
ret = -EINVAL;
goto out;
}
if (!last_extent)
goto retry;
}
When the first extent is unaligned and roundup(nr_pblocks, blks_per_sec)
exceeds sis->max, we subtract blks_per_sec resulting in nr_pblocks = 0. The
code then incorrectly assumes this is the last extent, sets nr_pblocks =
last_lblock - cur_lblock (entire swapfile), and performs migration. After
migration, it doesn't retry mapping, so subsequent extents are never processed.
"
In order to fix this issue, we need to lookup block mapping info after
we migrate all blocks in the tail of swapfile.

"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nf2fs: fix to avoid mapping wrong physical block for swapfile\n\nXiaolong Guo reported a f2fs bug in bugzilla [1]\n\n[1] https://bugzilla.kernel.org/show_bug.cgi?id=220951\n\nQuoted:\n\n\"When using stress-ng\u0027s swap stress test on F2FS filesystem with kernel 6.6+,\nthe system experiences data corruption leading to either:\n1 dm-verity corruption errors and device reboot\n2 F2FS node corruption errors and boot hangs\n\nThe issue occurs specifically when:\n1 Using F2FS filesystem (ext4 is unaffected)\n2 Swapfile size is less than F2FS section size (2MB)\n3 Swapfile has fragmented physical layout (multiple non-contiguous extents)\n4 Kernel version is 6.6+ (6.1 is unaffected)\n\nThe root cause is in check_swap_activate() function in fs/f2fs/data.c. When the\nfirst extent of a small swapfile (\u003c 2MB) is not aligned to section boundaries,\nthe function incorrectly treats it as the last extent, failing to map\nsubsequent extents. This results in incorrect swap_extent creation where only\nthe first extent is mapped, causing subsequent swap writes to overwrite wrong\nphysical locations (other files\u0027 data).\n\nSteps to Reproduce\n1 Setup a device with F2FS-formatted userdata partition\n2 Compile stress-ng from https://github.com/ColinIanKing/stress-ng\n3 Run swap stress test: (Android devices)\nadb shell \"cd /data/stressng; ./stress-ng-64 --metrics-brief --timeout 60\n--swap 0\"\n\nLog:\n1 Ftrace shows in kernel 6.6, only first extent is mapped during second\nf2fs_map_blocks call in check_swap_activate():\nstress-ng-swap-8990: f2fs_map_blocks: ino=11002, file offset=0, start\nblkaddr=0x43143, len=0x1\n(Only 4KB mapped, not the full swapfile)\n2 in kernel 6.1, both extents are correctly mapped:\nstress-ng-swap-5966: f2fs_map_blocks: ino=28011, file offset=0, start\nblkaddr=0x13cd4, len=0x1\nstress-ng-swap-5966: f2fs_map_blocks: ino=28011, file offset=1, start\nblkaddr=0x60c84b, len=0xff\n\nThe problematic code is in check_swap_activate():\nif ((pblock - SM_I(sbi)-\u003emain_blkaddr) % blks_per_sec ||\n nr_pblocks % blks_per_sec ||\n !f2fs_valid_pinned_area(sbi, pblock)) {\n bool last_extent = false;\n\n not_aligned++;\n\n nr_pblocks = roundup(nr_pblocks, blks_per_sec);\n if (cur_lblock + nr_pblocks \u003e sis-\u003emax)\n nr_pblocks -= blks_per_sec;\n\n /* this extent is last one */\n if (!nr_pblocks) {\n nr_pblocks = last_lblock - cur_lblock;\n last_extent = true;\n }\n\n ret = f2fs_migrate_blocks(inode, cur_lblock, nr_pblocks);\n if (ret) {\n if (ret == -ENOENT)\n ret = -EINVAL;\n goto out;\n }\n\n if (!last_extent)\n goto retry;\n}\n\nWhen the first extent is unaligned and roundup(nr_pblocks, blks_per_sec)\nexceeds sis-\u003emax, we subtract blks_per_sec resulting in nr_pblocks = 0. The\ncode then incorrectly assumes this is the last extent, sets nr_pblocks =\nlast_lblock - cur_lblock (entire swapfile), and performs migration. After\nmigration, it doesn\u0027t retry mapping, so subsequent extents are never processed.\n\"\n\nIn order to fix this issue, we need to lookup block mapping info after\nwe migrate all blocks in the tail of swapfile."

Most routines in qla_bsg.c call bsg_done() only for success cases.
However a few invoke it for failure case as well leading to a double
free. Validate before calling bsg_done().

Title
netfilter: nf_tables: fix use-after-free in nf_tables_addchain()
Summary
In the Linux kernel, the following vulnerability has been resolved:
netfilter: nf_tables: fix use-after-free in nf_tables_addchain()
nf_tables_addchain() publishes the chain to table->chains via
list_add_tail_rcu() (in nft_chain_add()) before registering hooks.
If nf_tables_register_hook() then fails, the error path calls
nft_chain_del() (list_del_rcu()) followed by nf_tables_chain_destroy()
with no RCU grace period in between.
This creates two use-after-free conditions:
1) Control-plane: nf_tables_dump_chains() traverses table->chains
under rcu_read_lock(). A concurrent dump can still be walking
the chain when the error path frees it.
2) Packet path: for NFPROTO_INET, nf_register_net_hook() briefly
installs the IPv4 hook before IPv6 registration fails. Packets
entering nft_do_chain() via the transient IPv4 hook can still be
dereferencing chain->blob_gen_X when the error path frees the
chain.
Add synchronize_rcu() between nft_chain_del() and the chain destroy
so that all RCU readers -- both dump threads and in-flight packet
evaluation -- have finished before the chain is freed.

Title
smb: client: split cached_fid bitfields to avoid shared-byte RMW races
Summary
In the Linux kernel, the following vulnerability has been resolved:
smb: client: split cached_fid bitfields to avoid shared-byte RMW races
is_open, has_lease and on_list are stored in the same bitfield byte in
struct cached_fid but are updated in different code paths that may run
concurrently. Bitfield assignments generate byte read–modify–write
operations (e.g. `orb $mask, addr` on x86_64), so updating one flag can
restore stale values of the others.
A possible interleaving is:
CPU1: load old byte (has_lease=1, on_list=1)
CPU2: clear both flags (store 0)
CPU1: RMW store (old | IS_OPEN) -> reintroduces cleared bits
To avoid this class of races, convert these flags to separate bool
fields.

Title
crypto: virtio - Add spinlock protection with virtqueue notification
Summary
In the Linux kernel, the following vulnerability has been resolved:
crypto: virtio - Add spinlock protection with virtqueue notification
When VM boots with one virtio-crypto PCI device and builtin backend,
run openssl benchmark command with multiple processes, such as
openssl speed -evp aes-128-cbc -engine afalg -seconds 10 -multi 32
openssl processes will hangup and there is error reported like this:
virtio_crypto virtio0: dataq.0:id 3 is not a head!
It seems that the data virtqueue need protection when it is handled
for virtio done notification. If the spinlock protection is added
in virtcrypto_done_task(), openssl benchmark with multiple processes
works well.
Severity ?
No CVSS data available.

Title
smb: server: fix leak of active_num_conn in ksmbd_tcp_new_connection()
Summary
In the Linux kernel, the following vulnerability has been resolved:
smb: server: fix leak of active_num_conn in ksmbd_tcp_new_connection()
On kthread_run() failure in ksmbd_tcp_new_connection(), the transport is
freed via free_transport(), which does not decrement active_num_conn,
leaking this counter.
Replace free_transport() with ksmbd_tcp_disconnect().

Title
drm/exynos: vidi: use ctx->lock to protect struct vidi_context member variables related to memory alloc/free
Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/exynos: vidi: use ctx->lock to protect struct vidi_context member variables related to memory alloc/free
Exynos Virtual Display driver performs memory alloc/free operations
without lock protection, which easily causes concurrency problem.
For example, use-after-free can occur in race scenario like this:
```
CPU0 CPU1 CPU2
---- ---- ----
vidi_connection_ioctl()
if (vidi->connection) // true
drm_edid = drm_edid_alloc(); // alloc drm_edid
...
ctx->raw_edid = drm_edid;
...
drm_mode_getconnector()
drm_helper_probe_single_connector_modes()
vidi_get_modes()
if (ctx->raw_edid) // true
drm_edid_dup(ctx->raw_edid);
if (!drm_edid) // false
...
vidi_connection_ioctl()
if (vidi->connection) // false
drm_edid_free(ctx->raw_edid); // free drm_edid
...
drm_edid_alloc(drm_edid->edid)
kmemdup(edid); // UAF!!
...
```
To prevent these vulns, at least in vidi_context, member variables related
to memory alloc/free should be protected with ctx->lock.

Title
ksmbd: add chann_lock to protect ksmbd_chann_list xarray
Summary
In the Linux kernel, the following vulnerability has been resolved:
ksmbd: add chann_lock to protect ksmbd_chann_list xarray
ksmbd_chann_list xarray lacks synchronization, allowing use-after-free in
multi-channel sessions (between lookup_chann_list() and ksmbd_chann_del).
Adds rw_semaphore chann_lock to struct ksmbd_session and protects
all xa_load/xa_store/xa_erase accesses.

Title
sched/mmcid: Don't assume CID is CPU owned on mode switch
Summary
In the Linux kernel, the following vulnerability has been resolved:
sched/mmcid: Don't assume CID is CPU owned on mode switch
Shinichiro reported a KASAN UAF, which is actually an out of bounds access
in the MMCID management code.
CPU0 CPU1
T1 runs in userspace
T0: fork(T4) -> Switch to per CPU CID mode
fixup() set MM_CID_TRANSIT on T1/CPU1
T4 exit()
T3 exit()
T2 exit()
T1 exit() switch to per task mode
---> Out of bounds access.
As T1 has not scheduled after T0 set the TRANSIT bit, it exits with the
TRANSIT bit set. sched_mm_cid_remove_user() clears the TRANSIT bit in
the task and drops the CID, but it does not touch the per CPU storage.
That's functionally correct because a CID is only owned by the CPU when
the ONCPU bit is set, which is mutually exclusive with the TRANSIT flag.
Now sched_mm_cid_exit() assumes that the CID is CPU owned because the
prior mode was per CPU. It invokes mm_drop_cid_on_cpu() which clears the
not set ONCPU bit and then invokes clear_bit() with an insanely large
bit number because TRANSIT is set (bit 29).
Prevent that by actually validating that the CID is CPU owned in
mm_drop_cid_on_cpu().
Severity ?

In the Linux kernel, the following vulnerability has been resolved:
erofs: fix UAF issue for file-backed mounts w/ directio option

EROFS may encounter above panic when enabling file-backed mount w/
directio mount option, the root cause is it may suffer UAF in below
race condition:
- z_erofs_read_folio wq s_dio_done_wq
- z_erofs_runqueue
- erofs_fileio_submit_bio
- erofs_fileio_rq_submit
- vfs_iocb_iter_read
- ext4_file_read_iter
- ext4_dio_read_iter
- iomap_dio_rw
: bio was submitted and return -EIOCBQUEUED
- dio_aio_complete_work
- dio_complete
- dio->iocb->ki_complete (erofs_fileio_ki_complete())
- kfree(rq)
: it frees iocb, iocb.ki_filp can be UAF in file_accessed().
- file_accessed
: access NULL file point
Introduce a reference count in struct erofs_fileio_rq, and initialize it
as two, both erofs_fileio_ki_complete() and erofs_fileio_rq_submit() will
decrease reference count, the last one decreasing the reference count
to zero will free rq.

Title
xfs: fix UAF in xchk_btree_check_block_owner
Summary
In the Linux kernel, the following vulnerability has been resolved:
xfs: fix UAF in xchk_btree_check_block_owner
We cannot dereference bs->cur when trying to determine if bs->cur
aliases bs->sc->sa.{bno,rmap}_cur after the latter has been freed.
Fix this by sampling before type before any freeing could happen.
The correct temporal ordering was broken when we removed xfs_btnum_t.
Severity ?
No CVSS data available.

Title
crypto: omap - Allocate OMAP_CRYPTO_FORCE_COPY scatterlists correctly
Summary
In the Linux kernel, the following vulnerability has been resolved:
crypto: omap - Allocate OMAP_CRYPTO_FORCE_COPY scatterlists correctly
The existing allocation of scatterlists in omap_crypto_copy_sg_lists()
was allocating an array of scatterlist pointers, not scatterlist objects,
resulting in a 4x too small allocation.
Use sizeof(*new_sg) to get the correct object size.
Severity ?

Title
bus: fsl-mc: fix use-after-free in driver_override_show()
Summary
In the Linux kernel, the following vulnerability has been resolved:
bus: fsl-mc: fix use-after-free in driver_override_show()
The driver_override_show() function reads the driver_override string
without holding the device_lock. However, driver_override_store() uses
driver_set_override(), which modifies and frees the string while holding
the device_lock.
This can result in a concurrent use-after-free if the string is freed
by the store function while being read by the show function.
Fix this by holding the device_lock around the read operation.
Severity ?
No CVSS data available.

Title
ksmbd: fix infinite loop caused by next_smb2_rcv_hdr_off reset in error paths
Summary
In the Linux kernel, the following vulnerability has been resolved:
ksmbd: fix infinite loop caused by next_smb2_rcv_hdr_off reset in error paths
The problem occurs when a signed request fails smb2 signature verification
check. In __process_request(), if check_sign_req() returns an error,
set_smb2_rsp_status(work, STATUS_ACCESS_DENIED) is called.
set_smb2_rsp_status() set work->next_smb2_rcv_hdr_off as zero. By resetting
next_smb2_rcv_hdr_off to zero, the pointer to the next command in the chain
is lost. Consequently, is_chained_smb2_message() continues to point to
the same request header instead of advancing. If the header's NextCommand
field is non-zero, the function returns true, causing __handle_ksmbd_work()
to repeatedly process the same failed request in an infinite loop.
This results in the kernel log being flooded with "bad smb2 signature"
messages and high CPU usage.
This patch fixes the issue by changing the return value from
SERVER_HANDLER_CONTINUE to SERVER_HANDLER_ABORT. This ensures that
the processing loop terminates immediately rather than attempting to
continue from an invalidated offset.

Title
nilfs2: Fix potential block overflow that cause system hang
Summary
In the Linux kernel, the following vulnerability has been resolved:
nilfs2: Fix potential block overflow that cause system hang
When a user executes the FITRIM command, an underflow can occur when
calculating nblocks if end_block is too small. Since nblocks is of
type sector_t, which is u64, a negative nblocks value will become a
very large positive integer. This ultimately leads to the block layer
function __blkdev_issue_discard() taking an excessively long time to
process the bio chain, and the ns_segctor_sem lock remains held for a
long period. This prevents other tasks from acquiring the ns_segctor_sem
lock, resulting in the hang reported by syzbot in [1].
If the ending block is too small, typically if it is smaller than 4KiB
range, depending on the usage of the segment 0, it may be possible to
attempt a discard request beyond the device size causing the hang.
Exiting successfully and assign the discarded size (0 in this case)
to range->len.
Although the start and len values in the user input range are too small,
a conservative strategy is adopted here to safely ignore them, which is
equivalent to a no-op; it will not perform any trimming and will not
throw an error.

This ultimately leads to the block layer\nfunction __blkdev_issue_discard() taking an excessively long time to\nprocess the bio chain, and the ns_segctor_sem lock remains held for a\nlong period. This prevents other tasks from acquiring the ns_segctor_sem\nlock, resulting in the hang reported by syzbot in [1].\n\nIf the ending block is too small, typically if it is smaller than 4KiB\nrange, depending on the usage of the segment 0, it may be possible to\nattempt a discard request beyond the device size causing the hang.\n\nExiting successfully and assign the discarded size (0 in this case)\nto range-\u003elen.\n\nAlthough the start and len values in the user input range are too small,\na conservative strategy is adopted here to safely ignore them, which is\nequivalent to a no-op; it will not perform any trimming and will not\nthrow an error.\n\n[1]\ntask:segctord state:D stack:28968 pid:6093 tgid:6093 ppid:2 task_flags:0x200040 flags:0x00080000\nCall Trace:\n rwbase_write_lock+0x3dd/0x750 kernel/locking/rwbase_rt.c:272\n nilfs_transaction_lock+0x253/0x4c0 fs/nilfs2/segment.c:357\n nilfs_segctor_thread_construct fs/nilfs2/segment.c:2569 [inline]\n nilfs_segctor_thread+0x6ec/0xe00 fs/nilfs2/segment.c:2684\n\n[ryusuke: corrected part of the commit message about the consequences]"

The root cause of this was that there was a free (dma_free_attrs) in the
interrupt context. There was a device discovery/fabric scan in
progress. A module unload was issued which set the UNLOADING flag. As
part of the discovery, after receiving an interrupt a work queue was
scheduled (which involved a work to be queued). Since the UNLOADING
flag is set, the work item was not allocated and the mapped memory had
to be freed. The free occurred in interrupt context leading to system
crash. Delay the driver unload until the fabric scan is complete to
avoid the crash.

Title
wifi: rtl8xxxu: fix slab-out-of-bounds in rtl8xxxu_sta_add
Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: rtl8xxxu: fix slab-out-of-bounds in rtl8xxxu_sta_add
The driver does not set hw->sta_data_size, which causes mac80211 to
allocate insufficient space for driver private station data in
__sta_info_alloc(). When rtl8xxxu_sta_add() accesses members of
struct rtl8xxxu_sta_info through sta->drv_priv, this results in a
slab-out-of-bounds write.
KASAN report on RISC-V (VisionFive 2) with RTL8192EU adapter:
BUG: KASAN: slab-out-of-bounds in rtl8xxxu_sta_add+0x31c/0x346
Write of size 8 at addr ffffffd6d3e9ae88 by task kworker/u16:0/12
Set hw->sta_data_size to sizeof(struct rtl8xxxu_sta_info) during
probe, similar to how hw->vif_data_size is configured. This ensures
mac80211 allocates sufficient space for the driver's per-station
private data.
Tested on StarFive VisionFive 2 v1.2A board.

Title
PCI: endpoint: Avoid creating sub-groups asynchronously
Summary
In the Linux kernel, the following vulnerability has been resolved:
PCI: endpoint: Avoid creating sub-groups asynchronously
The asynchronous creation of sub-groups by a delayed work could lead to a
NULL pointer dereference when the driver directory is removed before the
work completes.
The crash can be easily reproduced with the following commands:
# cd /sys/kernel/config/pci_ep/functions/pci_epf_test
# for i in {1..20}; do mkdir test && rmdir test; done
BUG: kernel NULL pointer dereference, address: 0000000000000088
...
Call Trace:
configfs_register_group+0x3d/0x190
pci_epf_cfs_work+0x41/0x110
process_one_work+0x18f/0x350
worker_thread+0x25a/0x3a0
Fix this issue by using configfs_add_default_group() API which does not
have the deadlock problem as configfs_register_group() and does not require
the delayed work handler.
[mani: slightly reworded the description and added stable list]

"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nPCI: endpoint: Avoid creating sub-groups asynchronously\n\nThe asynchronous creation of sub-groups by a delayed work could lead to a\nNULL pointer dereference when the driver directory is removed before the\nwork completes.\n\nThe crash can be easily reproduced with the following commands:\n\n # cd /sys/kernel/config/pci_ep/functions/pci_epf_test\n # for i in {1..20}; do mkdir test \u0026\u0026 rmdir test; done\n\n BUG: kernel NULL pointer dereference, address: 0000000000000088\n ...\n Call Trace:\n configfs_register_group+0x3d/0x190\n pci_epf_cfs_work+0x41/0x110\n process_one_work+0x18f/0x350\n worker_thread+0x25a/0x3a0\n\nFix this issue by using configfs_add_default_group() API which does not\nhave the deadlock problem as configfs_register_group() and does not require\nthe delayed work handler.\n\n[mani: slightly reworded the description and added stable list]"
