What to do

AI-suggested

A fix for this vulnerability has been implemented in the Linux kernel. Users and administrators should apply the official kernel updates that include this patch to remediate the issue. Since this is a kernel-level fix, upgrading to a fixed kernel version is the recommended mitigation.

Description

A memory leak vulnerability in the Linux kernel's netfilter nf_tables subsystem was fixed. The issue arises from improper reference count restoration during abort paths involving delete element and delete set commands, potentially causing resource leaks. The fix involves checking for inactive elements and skipping redundant state restoration.
