CVE-2007-6712 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2007-6712):
  Integer overflow in the hrtimer_forward function (hrtimer.c) in Linux kernel
  2.6.21-rc4, when running on 64-bit systems, allows local users to cause a
  denial of service (infinite loop) via a timer with a large expiry value,
  which causes the timer to always be expired.
