How to fix?

Upgrade torvalds/linux to version 3.14.6 or higher.

Overview

Affected versions of this package are vulnerable to Race Condition. 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.
