| In the Linux kernel, the following vulnerability has been resolved:
ALSA: seq: avoid stale FIFO cells during resize
snd_seq_fifo_resize() still needs to publish the replacement pool
before it waits for FIFO users. A blocking snd_seq_read() holds
f->use_lock while it sleeps, so concurrent senders must be able to
queue to the new pool and wake that reader instead of failing against a
closing old pool.
However, snd_seq_fifo_event_in() duplicates an event before it takes
f->lock, and snd_seq_read() can dequeue a cell and later call
snd_seq_fifo_cell_putback() if copy_to_user() or
snd_seq_expand_var_event() fails. If resize swaps f->pool and detaches
oldhead in between, either path can relink an old-pool cell after the
snapshot. That stale cell sits outside the drained oldhead list, keeps
oldpool->counter elevated, and can leave snd_seq_pool_delete() waiting
for the retired pool to drain.
Keep the existing swap-before-wait ordering in snd_seq_fifo_resize(),
but reject stale cells before any FIFO relink. Revalidate event-in cells
under f->lock and retry them against the published replacement pool, and
free stale putback cells instead of linking them back into the FIFO.
The buggy scenario involves two paths, with each column showing the
order within that path:
resize path: relink path:
1. Allocate newpool. 1. Take f->use_lock.
2. Swap f->pool to newpool and 2. Duplicate or dequeue an old-pool
detach oldhead. cell before oldpool closes.
3. Mark oldpool closing and 3. Reach a later relink point after
wait for FIFO users. resize published newpool.
4. Free oldhead and delete 4. Relink the old-pool cell after
oldpool. resize detached oldhead.
5. Drop f->use_lock.
The reproducer reports a resize ioctl blocked in the expected pool
teardown path:

sockmap: Fix use-after-free in udp_bpf_recvmsg()
syzbot reported use-after-free of struct sk_msg in sk_msg_recvmsg(). [0]
sk_msg_recvmsg() peeks sk_msg from psock->ingress_msg under a lock,
but its processing is lockless.
Thus, sk_msg_recvmsg() must be serialised by callers, otherwise
multiple threads could touch the same sk_msg.
For example, TCP uses lock_sock(), and AF_UNIX uses unix_sk(sk)->iolock.
Initially, udp_bpf_recvmsg() had used lock_sock(), but the cited
commit removed it.
Let's serialise sk_msg_recvmsg() with lock_sock() in udp_bpf_recvmsg().
Note that holding spin_lock_bh(&sk->sk_receive_queue.lock) is not
an option due to copy_page_to_iter() in sk_msg_recvmsg().

| In the Linux kernel, the following vulnerability has been resolved:
RDMA/bnxt_re: Free CQ toggle page after firmware teardown
Free the toggle page only after firmware teardown completes so that
an NQ interrupt arriving during bnxt_qplib_destroy_cq() won't write
the toggle value to an already-freed page. Move free_page() after
bnxt_qplib_destroy_cq. |
| In the Linux kernel, the following vulnerability has been resolved:
RDMA/bnxt_re: Add a max slot check for SQ
The variable WQE mode must be validated against
the maximum slots supported by HW. The max supported
value is 64K. Adding a max and min check and fail if user
supplied value is more than the max supported and zero. |
| In the Linux kernel, the following vulnerability has been resolved:
RDMA/irdma: Replace waitqueue and flag with completion
The driver previously used a waitqueue along with an explicit
request_done flag, but without proper barriers around request_done.
An earlier patch by Gui-Dong Han <hanguidong02@gmail.com> attempted
to fix this by adding the missing memory barriers. Rather than
adding the barriers, this patch replaces the waitqueue+flag with
a completion, which is designed for this exact purpose. |
| In the Linux kernel, the following vulnerability has been resolved:
net: serialize netif_running() check in enqueue_to_backlog()
Syzbot reported a KASAN slab-use-after-free in fib_rules_lookup().
The root cause is a race condition where packets can escape the backlog
flushing during device unregistration (e.g., during netns exit).
Commit e9e4dd3267d0 ("net: do not process device backlog during unregistration")
introduced a lockless netif_running() check in enqueue_to_backlog() to
prevent queuing packets to an unregistering device.
However, this creates a TOCTOU race window.
A lockless transmitter (like veth_xmit) can pass
the check before dev_close() clears IFF_UP. If the transmitter is then
delayed, flush_all_backlogs() can run and finish before the transmitter
grabs the backlog lock and queues the packet. The packet then escapes
the flush and triggers UAF later when processed.
Fix this by moving the netif_running() check inside the backlog lock.
This serializes the check with the flush work (which also grabs the lock).
We then either queue the packet before the flush runs (so it gets flushed),
or check netif_running() after the flush/close completes (so it gets dropped). |
| In the Linux kernel, the following vulnerability has been resolved:
soundwire: fix bug in sdw_add_element_group_count found by syzkaller
The original implementation caused an out-of-bounds memory access
in the sdw_add_element_group_count for-loop when i == num.
for (i = 0; i <= num; i++) {
if (rate == group->rates[i] && lane == group->lanes[i])
...
To fix this error, the function now checks for existing rate/lane
entries in the group(a function parameter) using a for-loop before
adding them.
No functional changes apart from this fix. |
| In the Linux kernel, the following vulnerability has been resolved:
md/raid1: fix writes_pending and barrier reference leaks on write failures
raid1_make_request() acquires a writes_pending reference with
md_write_start() before calling raid1_write_request(). Several failure
paths in raid1_write_request() complete the bio and return without
reaching the normal write completion path, causing the corresponding
md_write_end() to be skipped.
Make raid1_write_request() return a status indicating whether the write
request was successfully queued. This allows raid1_make_request() to
call md_write_end() when raid1_write_request() fails.
Additionally, if wait_blocked_rdev() fails after wait_barrier()
succeeds, the associated barrier reference is not released.
Call allow_barrier() before returning from that path to keep the barrier
accounting balanced. |
| In the Linux kernel, the following vulnerability has been resolved:
md/raid10: fix writes_pending leak on write request failures
