In the Linux kernel, the following vulnerability has been resolved: aio:
Fix null ptr deref in aio_complete() wakeup list_del_init_careful() needs
to be the last access to the wait queue entry - it effectively unlocks
access. Previously, finish_wait() would see the empty list head and skip
taking the lock, and then we’d return - but the completion path would still
attempt to do the wakeup after the task_struct pointer had been
overwritten.
