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 before 3.3.1, when KVM is used, allows guest OS users to cause a denial of service (host OS crash) by leveraging administrative access to the guest OS, related to the pmd_none_or_clear_bad function and page faults for huge pages.
