CVE-2025-68748: 
Linux Debian vulnerability analysis and mitigation

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().
