CVE-2011-0726 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2011-0726):
  The do_task_stat function in fs/proc/array.c in the Linux kernel before
  2.6.39-rc1 does not perform an expected uid check, which makes it easier for
  local users to defeat the ASLR protection mechanism by reading the
  start_code and end_code fields in the /proc/#####/stat file for a process
  executing a PIE binary.
