kernel: futex: refcount issue in case of requeue

A flaw was found in the way the Linux kernel's futex subsystem handled reference counting when requeuing futexes during futexwait. A local, unprivileged user could use this flaw to zero out the reference counter of an inode or an mm struct that backs up the memory area of the futex, which could...
