Linux kernel vmsplice() local privilege escalation exploit

http://secunia.com/advisories/28835/ - A bug in the vmsplice() call in the Linux kernel can allow a local user to escalate privileges to root. Sample code is available and has been verified as working. This bug affects kernel version 2.6.17 - 2.6.24.1, although the privilege escalation only works in the extended version of vmsplice() in 2.6.23 - 2.6.24. A patch partially fixing the bug is available in 2.6.24.2.
