high Tenable Cloud Security Plugin ID 466342

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_nat: reject unsupported
target families xt_nat SNAT and DNAT target handlers assume IP-family conntrack state is present and can
dereference a NULL pointer when instantiated from an unsupported family through nft_compat. A bridge-
family compat rule can therefore trigger a NULL-dereference in nf_nat_setup_info(). Reject non-IP families
in xt_nat_checkentry() so unsupported targets cannot be installed. Keep NFPROTO_INET allowed for valid
inet NAT compat users and leave the runtime fast path unchanged. [ The crash was fixed via 9dbba7e694ec
("netfilter: nft_compat: ebtables emulation must reject non-bridge targets"), so this patch is no longer
critical. Nevertheless, NAT is only relevant for ipv4/ipv6, so this extra family check is a good idea in
any case. ] (CVE-2026-80664)

Solution

Update the sys-kernel/csql-kernel-6_1 library and its related packages to version 18613.731.2 or later.
