Denial of Service Vulnerability in Linux Kernel's ldm_parse_vmdb Function

CVE-2011-1012 · MEDIUM Severity

AV:L/AC:L/AU:N/C:N/I:N/A:C

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.
