## Overview

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

pinctrl: aspeed: Fix potential NULL dereference in aspeed_pinmux_set_mux()

pdesc could be null but still dereference pdesc->name and it will lead to
a null pointer access. So we move a null check before dereference.

## Affected

- `linux_kernel < 5.10.132`
- `linux_kernel >= 5.11, < 5.15.56`
- `linux_kernel >= 5.16, < 5.18.13`
- `linux_kernel = 5.19`

## Remediation

Upgrade past the affected range:

- `linux_kernel 5.18.13`
