high Tenable Self-Hosted Container Security Plugin ID 469780

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: vsock/virtio: read virtqueues under
worker locks Commit bd50c5dc182b ("vsock/virtio: add support for device suspend/resume") made the *_run
flags transition from false to true when restore installs replacement virtqueues. The RX, TX and event
workers read their virtqueue before locking and checking the corresponding flag, so a worker delayed
across freeze and restore can observe the replacement queue's running state while retaining a pointer to
the deleted queue. Read each virtqueue under its mutex after checking the run flag, keeping the pointer
and state in the same queue generation. (CVE-2026-74614)

Solution

Update the sys-kernel/cchost-kernel-6_12 library and its related packages to version 19506.448.8 or later.
