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: x_tables: add and use
xtables_unregister_table_exit Previous change added xtables_unregister_table_pre_exit to detach the table
from the packetpath and to unlink it from the active table list. In case of rmmod, userspace that is doing
set/getsockopt for this table will not be able to re-instantiate the table: 1. The larval table has been
removed already 2. existing instantiated table is no longer on the xt pernet table list. This adds the
second stage helper: unlink the table from the dying list, free the hook ops (if any) and do the audit
notification. It replaces xt_unregister_table(). (CVE-2026-64078)

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