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: ipv4: fib: bound automatic table ID
allocation fib_empty_table() probes every table ID from 1 until it finds a free one. IPv4 tables are
stored in a 256-bucket hash table, so a dense set of IDs makes each probe walk a growing hash chain while
RTNL is held. Automatic table assignment ("ip rule ... table 0") is an IPv4-only legacy path. Bound the
automatically allocated ID to 4096 so the RTNL hold stays bounded, without changing lookups of explicitly
specified table IDs. This changes user-visible behavior. A table-0 rule previously received the lowest
free ID in 1..RT_TABLE_MAX (0xFFFFFFFF). After this patch the search stops at 4096 and the rule add fails
with ENOBUFS if that range is fully occupied. Explicit table IDs above 4096 remain usable. The automatic
path is unused in practice: it is IPv4-only, not documented by ip-rule, uncovered by kernel selftests, and
both NetworkManager and systemd refuse table 0. (CVE-2026-97598)

Solution

Update the sys-kernel/cchost-kernel-6_12 library and its related packages to version 19999.44.106 or later.
