CVE-2011-1012: Canonical Ubuntu Linux

Medium severity, CVSS 4.9. EPSS: 0.5% chance of exploitation in the next 30 days.

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.

Affected products

• Canonical Ubuntu Linux: version 8.04 only
• Linux Linux Kernel: before 2.6.38 (fixed in 2.6.38); version 2.6.38 only
