CVE-2025-39860

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: Fix use-after-free in l2cap_sock_cleanup_listen() syzbot reported the splat below without a repro. In the splat, a single thread calling bt_accept_dequeue() freed sk and touched it after that. The root cause would be the racy l2cap_sock_cleanup_listen() call added by the cited commit. bt_accept_dequeue() is called under lock_sock() except for l2cap_sock_release(). Two threads could see the same socket during the list iteration in bt_accept_dequeue(): CPU1 CPU2 (close()) ---- ---- sock_hold(sk) sock_hold(sk); lock_sock(sk) <-- block close() sock_put(sk) bt_accept_unlink(sk) sock_put(sk) <-- refcnt by bt_accept_enqueue() release_sock(sk) lock_sock(sk) sock_put(sk) bt_accept_unlink(sk) sock_put(sk) <-- last refcnt bt_accept_unlink(sk) <-- UAF Depending on the timing, the other thread could show up in the "Freed by task" part.

In the Linux kernel, the following vulnerability has been resolved:

drm/amd/display: avoid NPD when ASIC does not support DMUB

ctx->dmub_srv will de NULL if the ASIC does not support DMUB, which is tested in dm_dmub_sw_init.

However, it will be dereferenced in dmub_hw_lock_mgr_cmd if should_use_dmub_lock returns true.

This has been the case since dmub support has been added for PSR1.

Fix this by checking for dmub_srv in should_use_dmub_lock.

openvswitch: Fix unsafe attribute parsing in output_userspace()

In the Linux kernel, the following vulnerability has been resolved:

comedi: pcl726: Prevent invalid irq number

The reproducer passed in an irq number(0x80008000) that was too large, which triggered the oob.

Added an interrupt number check to prevent users from passing in an irq number that was too large.

If it->options[1] is 31, then 1 << it->options[1] is still invalid because it shifts a 1-bit into the sign bit (which is UB in C). Possible solutions include reducing the upper bound on the it->options[1] value to 30 or lower, or using 1U << it->options[1].

The old code would just not attempt to request the IRQ if the options[1] value were invalid. And it would still configure the device without interrupts even if the call to request_irq returned an error. So it would be better to combine this test with the test below.(CVE-2025-39685)

In the Linux kernel, the following vulnerability has been resolved:

ACPI: pfr_update: Fix the driver update version check

The security-version-number check should be used rather than the runtime version check for driver updates.

Otherwise, the firmware update would fail when the update binary had a lower runtime version number than the current one.

mm/vmscan: fix hwpoisoned large folio handling in shrink_folio_list

In shrink_folio_list(), the hwpoisoned folio may be large folio, which can't be handled by unmap_poisoned_folio(). For THP, try_to_unmap_one() must be passed with TTU_SPLIT_HUGE_PMD to split huge PMD first and then retry. Without TTU_SPLIT_HUGE_PMD, we will trigger null-ptr deref of pvmw.pte. Even we passed TTU_SPLIT_HUGE_PMD, we will trigger a WARN_ON_ONCE due to the page isn't in swapcache.

Since UCE is rare in real world, and race with reclaimation is more rare, just skipping the hwpoisoned large folio is enough. …

What`s more, we change spin_lock_bh() inrtw_scan_timeout_handler() to spin_lock_irq(). Otherwise,spin_lock_bh() will also cause deadlock() in timer handler.(CVE-2022-49309)
