- Summary
- [none]
- Details
-
The futexwaitrequeuepi 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 FUTEXWAITREQUEUEPI command.
