CVE-2010-0622 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2010-0622):
  The wake_futex_pi function in kernel/futex.c in the Linux kernel
  before 2.6.33-rc7 does not properly handle certain unlock operations
  for a Priority Inheritance (PI) futex, which allows local users to
  cause a denial of service (OOPS) and possibly have unspecified other
  impact via vectors involving modification of the futex value from
  user space.
