Description
A vulnerability was found in the Linux kernel that causes a NULL pointer dereference in the aio_complete() function during a wakeup operation. The issue arises because finish_wait() may skip locking if it encounters an empty list head. This leads to a NULL pointer dereference when attempting a wakeup after the task structure pointer is overwritten.
