## Overview

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

netfilter: nf_tables: disallow timeout for anonymous sets

Never used from userspace, disallow these parameters.

## Affected

- `linux_kernel < 4.19.312`
- `linux_kernel >= 4.20, < 5.4.274`
- `linux_kernel >= 5.5, < 5.10.215`
- `linux_kernel >= 5.11, < 5.15.151`
- `linux_kernel >= 5.16, < 6.1.81`
- `linux_kernel >= 6.2, < 6.4`
- `linux_kernel = 6.4`

## Remediation

Upgrade past the affected range:

- `linux_kernel 6.4`
