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

Buffer overflow in the macvtap device driver in the Linux kernel before 3.4.5, when running in certain configurations, allows privileged KVM guest users to cause a denial of service (crash) via a long descriptor with a long vector length.
