CVE-2014-3940

Priority
Low
Description
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.
Ubuntu-Description
A flaw was discovered in the Linux kernel's handling of hugetlb entries. A
local user could exploit this flaw to cause a denial service (memory
corruption or system crash).
