CVE-2011-1012

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 ldm_parse_vmdb function in fs/partitions/ldm.c in the Linux kernel before 2.6.38-rc6-git6 does not validate the VBLK size value in the VMDB structure in an LDM partition table, which allows local users to cause a denial of service (divide-by-zero error and OOPS) via a crafted partition table.
