medium Tenable Cloud Security Plugin ID 468721

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: devlink: Release nested relation on
devlink free devlink relation state is normally released from devl_unregister(), which calls
devlink_rel_put(). This misses devlink instances that get a nested relation before registration and then
fail probe before devl_register() is reached. That flow can happen for SFs. The child devlink gets linked
to its parent before registration, then a later probe error calls devlink_free() directly. Since the
instance was never registered, devl_unregister() is not called and devlink->rel is leaked. Release any
pending relation from devlink_free() as well. The registered path is unchanged because devl_unregister()
already clears devlink->rel before devlink_free() runs. (CVE-2026-53261)

Solution

Update the sys-kernel/cchost-kernel-6_12 library and its related packages to version 19216.532.3 or later.
