A fix for this vulnerability has been implemented by adding synchronization to prevent the race condition. Since no explicit patch links or vendor advisories are provided, check the official Linux kernel repositories or vendor advisories for the updated drm/panthor driver version containing this fix and apply it promptly.
Description
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().
