## Overview

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

Flaw in the error handling of bound chains causes a use-after-free in the abort path of NFT_MSG_NEWRULE. The vulnerability requires CAP_NET_ADMIN to be triggered.

We recommend upgrading past commit 4bedf9eee016286c835e3d8fa981ddece5338795.

## Affected

- `linux_kernel >= 5.9, < 5.10.188`
- `linux_kernel >= 5.11, < 5.15.119`
- `linux_kernel >= 5.16, < 6.1.36`
- `linux_kernel >= 6.2, < 6.3.10`
- `debian_linux = 10.0`
- `debian_linux = 11.0`

## Remediation

Upgrade past the affected range:

- `linux_kernel 6.3.10`
