Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- In the Linux kernel, the following vulnerability has been resolved: dm: fix NULL pointer dereference in
__dm_suspend() There is a race condition between dm device suspend and table load that can lead to null
pointer dereference. The issue occurs when suspend is invoked before table load completes: BUG: kernel
NULL pointer dereference, address: 0000000000000054 Oops: 0000 [#1] PREEMPT SMP PTI CPU: 6 PID: 6798 Comm:

issue can be triggered as below: T1 T2 dm_suspend table_load __dm_suspend dm_setup_md_queue
dm_mq_init_request_queue blk_mq_init_allocated_queue => q->mq_ops = set->ops; (1) dm_stop_queue /
dm_wait_for_completion => q->tag_set NULL pointer! (2) => q->tag_set = set; (3) Fix this by checking if a
valid table (map) exists before performing request-based suspend and waiting for target I/O. When map is
NULL, skip these table-dependent suspend steps. Even when map is NULL, no I/O can reach any target because
there is no table loaded; I/O submitted in this state will fail early in the DM layer. Skipping the table-
dependent suspend logic in this case is safe and avoids NULL pointer dereferences. (CVE-2025-40134)

Solution

Update the sys-kernel/csql-kernel-6_12 library and its related packages to version 19216.104.3 or later.
