CWEhttps://cwe.mitre.org/data/definitions/369.html

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.

The product divides a value by zero.
