high Tenable Cloud Security Plugin ID 470310

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: apparmor: fix race in unix socket
mediation when peer_path is used The holding a reference to the peer_sk is not enough to ensure access to
the peer sk path. Accessing the path outside of the state lock allows for a race with unix_release_sock().
Fix this by taking the state lock and getting a reference to the path under lock. Ideally for connected
sockets we would cache this information so we don't have to take the lock here. But for now just fix the
race. (CVE-2026-72462)

Solution

Update the sys-kernel/cchost-kernel-6_18 library and its related packages to version 19999.44.21 or later.
