## Overview

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

drm/panthor: Fix NULL pointer dereference on panthor_fw_unplug

This patch removes the MCU halt and wait for halt procedures during
panthor_fw_unplug() as the MCU can be in a variety of states or the FW
may not even be loaded/initialized at all, the latter of which can lead
to a NULL pointer dereference.

It should be safe on unplug to just disable the MCU without waiting for
it to halt as it may not be able to.

## Affected

- `linux_kernel >= 6.19, < 6.19.4`

## Remediation

Upgrade past the affected range:

- `linux_kernel 6.19.4`
