medium Tenable Cloud Security Plugin ID 464419

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: ipset: drop logically empty
 buckets in mtype_del mtype_del() counts empty slots below n->pos in k, but it only drops the bucket when
 both n->pos and k are zero. This misses buckets whose live entries have all been removed while n->pos
 still points past deleted slots. Treat a bucket as empty when all positions below n->pos are unused and
 release it directly instead of shrinking it further. (CVE-2026-31418)

Solution

Update the linux library and its related packages to version 6.1.170-1 or later.
