## 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.

## Affected

- `linux_kernel >= 5.8, < 7.0.10`
- `linux_kernel = 7.1`

## Remediation

Upgrade past the affected range:

- `linux_kernel 7.0.10`
