high Tenable Self-Hosted Container Security Plugin ID 472007

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: xsk: require at least 16 bytes of TX
metadata AF_XDP accepts a TX metadata length as small as eight bytes, but every supported request needs
the flags plus at least one eight-byte request field. Such short metadata also lets the kernel read beyond
the registered area. Require 16 bytes rather than sizeof(struct xsk_tx_metadata) to preserve compatibility
with applications that do not use launch-time metadata. (CVE-2026-74710)

Solution

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