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.

Security readout for executives and security teams

CVE-2014-3940 is a Linux kernel flaw that can let a local user crash or corrupt memory on an affected system. The sources describe denial of service, not remote compromise or data theft. Business urgency is highest for shared Linux systems, appliances, or hosting environments where untrusted users can run local processes. Exposure is most likely on Linux systems running kernel code through 3.14.5 or vendor kernels that carried the vulnerable behavior. The CVE metadata does not provide complete product CPEs, so appliance and distribution exposure must be confirmed through vendor advisories such as Red Hat and F5. Treat this as a reliability and availability risk, not a confirmed breach risk. Patch during normal security maintenance, but accelerate for shared systems, hosted environments, and critical appliances where local users or tenants could trigger a crash. Mitigation focus: Upgrade affected Linux kernels using vendor-supported security updates.; Check Red Hat, F5, and distribution advisories for product-specific fixes.; Prioritize multi-user systems and appliances with local shell access..
