## Overview

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

media: mtk-vcodec: potential null pointer deference in SCP

The return value of devm_kzalloc() needs to be checked to avoid
NULL pointer deference. This is similar to CVE-2022-3113.

## Affected

- `linux_kernel < 6.6.36`
- `linux_kernel >= 6.7, < 6.9.7`

## Remediation

Upgrade past the affected range:

- `linux_kernel 6.9.7`
