** 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.
