FKIE_CVE-2014-3940

Vulnerability from fkie_nvd - Published: 2014-06-05 17:55 - Updated: 2026-06-17 00:09
Severity
Summary
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.
