** Description changed:

  The Linux kernel through 3.14.5 does not properly consider the presence
  of hugetlb entries, which allows local users to cause a denial of
  service (memory corruption or system crash) by accessing certain memory
  locations, as demonstrated by triggering a race condition via numa_maps
  read operations during hugepage migration, related to fs/proc/task_mmu.c
  and mm/mempolicy.c.
