CVE-2011-1012

CVE-2011-1012 describes a denial-of-service vulnerability in the Linux kernel, specifically affecting versions before 2.6.38-rc6-git6, including Canonical Ubuntu Linux. The flaw resides in the ldm_parse_vmdb function, where improper validation of the VBLK size value in an LDM partition table can lead to a divide-by-zero error and system crash (OOPS). This is a low-severity vulnerability (CVSS 4.9) that can be exploited locally with low attack complexity, resulting in a complete loss of availability. There is no evidence of active exploitation, publicly available exploit code, or significant community discussion surrounding this CVE.
