New! CVE Severity Now Using CVSS v3

The calculated severity for CVEs has been updated to use CVSS v3 by default. CVEs that do not have a CVSS v3 score will fall back CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

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.
