critical Tenable Cloud Security Plugin ID 472136

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: inet: frags: publish queues before
 arming timer inet_frag_create() arms the fragment queue timer before inserting the queue into the fqdir
 rhashtable. If the namespace fragment timeout is zero or negative, the timer can run before the queue is
 published. The timer callback then marks the queue complete, tries to remove a node that is not in the
 hash table yet, and drops the anticipated hash reference. Creation can subsequently publish the completed
 queue without restoring that reference, leaving a stale hash node after the caller drops the remaining
 reference. Publish the queue first and arm the timer while holding the queue lock. This makes timer expiry
 wait until the queue is visible in the hash table, so inet_frag_kill() can remove the node and balance the
 hash reference. (CVE-2026-74662)

Solution

Update the sys-kernel/cchost-kernel-6_18 library and its related packages to version 20085.0.0 or later.
