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 ext4_fill_super function in fs/ext4/super.c in the Linux kernel before 2.6.39 does not properly initialize a certain error-report data structure, which allows local users to cause a denial of service (OOPS) by attempting to mount a crafted ext4 filesystem.
