medium Tenable Cloud Security Plugin ID 466168

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_cluster: reject template
conntracks in hash match xt_cluster_mt() treats any non-NULL nf_ct_get() result as a fully initialized
conntrack and passes it to xt_cluster_hash(). This causes a state confusion bug when the raw table CT
target attaches a template conntrack to skb->_nfct before normal conntrack processing. Templates carry
IPS_TEMPLATE status but do not have a valid tuple for hashing yet, so xt_cluster_hash() can hit its
WARN_ON() path on the zeroed l3num field. Reject template conntracks before hashing them. This matches
existing netfilter handling for template objects and avoids hashing incomplete conntrack state.
(CVE-2026-72256)

Solution

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