high Tenable Self-Hosted Container Security Plugin ID 468245

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: md/raid1: don't set array_frozen in
 raid1_takeover() raid1_takeover() sets conf->array_frozen = 1 on the newly-allocated r1conf and nothing
 ever clears it, so every I/O to the array stalls permanently once _wait_barrier() sees it stuck at 1. This
 used to be harmless: level_store() called mddev_resume() right after pers->run(), which called
 raid1_quiesce(mddev, 0) and cleared array_frozen back to 0 regardless of what raid1_takeover() set. Commit
 b39f35ebe86d ("md: don't quiesce in mddev_suspend()") removed that quiesce(mddev, 0) call, so the pre-set
 now sticks. setup_conf() already zero-initializes the new r1conf via kzalloc, so just don't set
 array_frozen here. Same class of bug as commit 892da88d1cd9 ("md/raid10: fix a 'conf->barrier' leakage in
 raid10_takeover()"), also triggered by b39f35ebe86d. (CVE-2026-90275)

Solution

Update the sys-kernel/cchost-kernel-6_12 library and its related packages to version 19216.700.7 or later.
