CWE-476 NULL Pointer Dereference

Description

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&#39;d return - but the completion path would still attempt to do the wakeup after the task_struct pointer had been overwritten.
