## Overview

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

netfilter: ebtables: module names must be null-terminated

We need to explicitly check the length, else we may pass non-null
terminated string to request_module().

## Affected

- `linux_kernel >= 4.6.1, < 5.10.261`
- `linux_kernel >= 5.11, < 5.15.212`
- `linux_kernel >= 5.16, < 6.1.178`
- `linux_kernel >= 6.2, < 6.6.145`
- `linux_kernel >= 6.7, < 6.12.96`
- `linux_kernel >= 6.13, < 6.18.39`
- `linux_kernel >= 6.19, < 7.1.4`
- `linux_kernel = 4.6`
- `linux_kernel = 7.2`

## Remediation

Upgrade past the affected range:

- `linux_kernel 7.1.4`
