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 agp subsystem in the Linux kernel 2.6.38.5 and earlier does not properly restrict memory allocation by the (1) AGPIOC_RESERVE and (2) AGPIOC_ALLOCATE ioctls, which allows local users to cause a denial of service (memory consumption) by making many calls to these ioctls.
