critical Tenable Self-Hosted Container Security Plugin ID 468939

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: smb: client: validate DFS referral
PathConsumed parse_dfs_referrals() validates that the response contains the fixed referral entry array
and, on for-next, the per-referral string offsets. However, the response also contains a PathConsumed
value that is later used for DFS path parsing. If a malformed response provides a PathConsumed value
larger than the search name, later DFS parsing can advance beyond the end of the path. Validate
PathConsumed against the search name length before storing it in the parsed referral. (CVE-2026-68343)

Solution

Update the sys-kernel/cchost-kernel-6_12 library and its related packages to version 19216.532.121 or later.
