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: jbd2: check need_resched() when
 skipping busy checkpoint buffers journal_shrink_one_cp_list() skips busy checkpoint buffers when called
 with JBD2_SHRINK_BUSY_SKIP. The continue statement on this path also skips the need_resched() check at the
 end of the loop body. Consequently, when a checkpoint list contains mostly busy buffers, the shrinker can
 walk the entire list while holding journal->j_list_lock, even when a reschedule has been requested. Large
 checkpoint lists under memory pressure can therefore cause long lock hold times and leave other CPUs
 spinning on j_list_lock, resulting in soft lockups or RCU stalls. Route the busy-buffer path through the
 need_resched() check so that the shrinker can release j_list_lock and reschedule promptly, restoring
 parity with the clean-buffer path, which already checks need_resched(). This does not change which
 checkpoint buffers are eligible for removal. (CVE-2026-89566)

Solution

Update the sys-kernel/cchost-kernel-6_12 library and its related packages to version 19999.44.106 or later.
