critical Tenable Self-Hosted Container Security Plugin ID 469899

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: Don't ignore error route in
 local/main tables. When CONFIG_IP_MULTIPLE_TABLES is enabled but no rule is added, fib_lookup() performs
 route lookup directly on two tables. Since the first lookup does not properly bail out, the result of an
 error route in the merged local/main table could be overwritten by another route in the default table: #
 unshare -n # ip link set lo up # ip route add 192.168.0.0/24 dev lo table 253 # ip route add unreachable
 192.168.0.0/24 # ip route get 192.168.0.1 192.168.0.1 dev lo table default uid 0 cache <local> Once a
 random rule is added, the error route is respected: # ip rule add table 0 # ip rule del table 0 # ip route
 get 192.168.0.1 RTNETLINK answers: No route to host Let's fix the inconsistent behaviour. (CVE-2026-72421)

Solution

Update the sys-kernel/cchost-kernel-6_12 library and its related packages to version 19506.448.8 or later.
