CVE-2014-3940
4.0 · MEDIUMOverview
CVE-2014-3940 is a medium-severity vulnerability affecting redhat enterprise_linux. It was published on June 5, 2014 and has a CVSS 2.0 base score of 4.0 (MEDIUM).
This vulnerability has a CVSS 2.0 base score of 4.0, rated MEDIUM. It requires local or adjacent network access to exploit. No authentication or special privileges are required for exploitation.
Technical 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.
Remediation
Check the references section for vendor advisories and patches from redhat. Update enterprise_linux to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
