Harald Welte 46113830a1 [PATCH] Fix signal sending in usbdevio on async URB completion ... If a process issues an URB from userspace and (starts to) terminate before the URB comes back, we run into the issue described above. This is because the urb saves a pointer to "current" when it is posted to the device, but there's no guarantee that this pointer is still valid afterwards. In fact, there are three separate issues: 1) the pointer to "current" can become invalid, since the task could be completely gone when the URB completion comes back from the device. 2) Even if the saved task pointer is still pointing to a valid task_struct, task_struct->sighand could have gone meanwhile. 3) Even if the process is perfectly fine, permissions may have changed, and we can no longer send it a signal. So what we do instead, is to save the PID and uid's of the process, and introduce a new kill_proc_info_as_uid() function.
