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: xt_policy: fix strict mode
inbound policy matching match_policy_in() walks sec_path entries from the last transform to the first one,
but strict policy matching needs to consume info->pol[] in the same forward order as the rule layout.
Derive the strict-match policy position from the number of transforms already consumed so that multi-
element inbound rules are matched consistently. (CVE-2026-52920)

Solution

Update the sys-kernel/cchost-kernel-6_12 library and its related packages to version 19862.0.0 or later.
