The futex_requeue function in kernel/futex.c in the Linux kernel through 3.14.5 does not ensure that calls have two different futex addresses, which allows local users to gain privileges via a crafted FUTEX_REQUEUE command that facilitates unsafe waiter modification.
The product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor.
