high Tenable Self-Hosted Container Security Plugin ID 468736

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: netfilter: ebtables: zero chainstack
array sashiko reports: looking at ebtables table translation, could a sparse cpu_possible_mask lead to an
uninitialized pointer free? If cpu_possible_mask is sparse (for example, CPU 0 and CPU 2 are possible, but
CPU 1 is not), the allocation loop skips CPU 1. If vmalloc_node() fails at CPU 2, the cleanup loop will
blindly decrement and call vfree() on newinfo->chainstack[1]. Not a real-world bug, such allocation isn't
expected to fail in the first place. (CVE-2026-64413)

Solution

Update the sys-kernel/cchost-kernel-6_12 library and its related packages to version 19216.532.96 or later.
