## Overview

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

drm/panthor: Fix UAF race between device unplug and FW event processing

The function panthor_fw_unplug() will free the FW memory sections.
The problem is that there could still be pending FW events which are yet
not handled at this point. process_fw_events_work() can in this case try
to access said freed memory.

Simply call disable_work_sync() to both drain and prevent future
invocation of process_fw_events_work().

## Remediation

Refer to the linked advisories for vendor-supplied fixes and affected version ranges.
