** Description changed: - [forbid uaddr == uaddr2 in futex_wait_requeue_pi() to avoid null - dereference] + The futex_wait_requeue_pi function in kernel/futex.c in the Linux kernel + before 3.5.1 does not ensure that calls have two different futex + addresses, which allows local users to cause a denial of service (NULL + pointer dereference and system crash) or possibly have unspecified other + impact via a crafted FUTEX_WAIT_REQUEUE_PI command. Break-Fix: 52400ba946759af28442dee6265c5c0180ac7122 6f7b0a2a5c0fb03be7c25bd1745baa50582348ef
