high Tenable Self-Hosted Container Security Plugin ID 465602

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: nft_set_pipapo: split gc
into unlink and reclaim phase Yiming Qian reports Use-after-free in the pipapo set type: Under a large
number of expired elements, commit-time GC can run for a very long time in a non-preemptible context,
triggering soft lockup warnings and RCU stall reports (local denial of service). We must split GC in an
unlink and a reclaim phase. We cannot queue elements for freeing until pointers have been swapped. Expired
elements are still exposed to both the packet path and userspace dumpers via the live copy of the data
structure. call_rcu() does not protect us: dump operations or element lookups starting after call_rcu has
fired can still observe the free'd element, unless the commit phase has made enough progress to swap the
clone and live pointers before any new reader has picked up the old version. This a similar approach as
done recently for the rbtree backend in commit 35f83a75529a ("netfilter: nft_set_rbtree: don't gc elements
on insert"). (CVE-2026-23351)

Solution

Update the sys-kernel/csql-kernel-6_1 library and its related packages to version 18613.534.53 or later.
