This crash is caused by a NULL pointer dereference of dev-&gt;raw pointer, even though it is checked for NULL in the same function, which means there is a race condition. It occurs due to the incorrect order of actions in the streamzap_disconnect() function: rc_unregister_device() is called before usb_kill_urb(). The dev-&gt;raw pointer is freed and set to NULL in rc_unregister_device(), and only after that usb_kill_urb() waits for in-progress requests to finish.</p> <p>If rc_unregister_device() is called while streamzap_callback() handler is not finished, this can lead to accessing freed resources. Thus rc_unregister_device() should be called after usb_kill_urb().</p> <p>Found by Linux Verification Center (linuxtesting.org) with Syzkaller.</p> <p><strong>Affected:</strong> Linux</p> <p>In the Linux kernel, the following vulnerability has been resolved:</p> <p>media: streamzap: fix race between device disconnection and urb callback</p> <p>Syzkaller has reported a general protection fault at function ir_raw_event_store_with_filter().
