## Overview

In the Linux kernel, the following vulnerability has been resolved:

netfilter: nf_tables: join hook list via splice_list_rcu() in commit phase

Publish new hooks in the list into the basechain/flowtable using
splice_list_rcu() to ensure netlink dump list traversal via rcu is safe
while concurrent ruleset update is going on.

## Remediation

Refer to the linked advisories for vendor-supplied fixes and affected version ranges.
