## Overview

A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited to achieve local privilege escalation.

Addition and removal of rules from chain bindings within the same transaction causes leads to use-after-free.

We recommend upgrading past commit f15f29fd4779be8a418b66e9d52979bb6d6c2325.

## Affected

- `debian_linux = 10.0`
- `linux_kernel >= 5.9.0, < 5.10.198`
- `linux_kernel >= 5.11, < 5.15.134`
- `linux_kernel >= 5.16, < 6.1.56`
- `linux_kernel >= 6.2, < 6.5.6`

## Remediation

Upgrade past the affected range:

- `linux_kernel 6.5.6`
