Vulnerability Description
The futex_wait function in kernel/futex.c in the Linux kernel before 2.6.37 does not properly maintain a certain reference count during requeue operations, which allows local users to cause a denial of service (use-after-free and system crash) or possibly gain privileges via a crafted application that triggers a zero count.
