Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 3.14.5
Description The issue allows local users to cause a denial of service, resulting in memory corruption or system crash, by accessing certain memory locations. This can be achieved by triggering a race condition via numa maps read operations during hugepage migration. The problem is related to the fs/proc/task mmu.c and mm/mempolicy.c files.
Recommendations For Linux kernel versions prior to 3.14.5, update to version 3.14.5 or later to resolve the issue. As a temporary workaround, consider restricting access to hugepage migration to minimize the risk of exploitation.
