This vulnerability has a CVSS 2.0 base score of 7.2, rated HIGH. It requires local or adjacent network access to exploit. No authentication or special privileges are required for exploitation.

Technical description

The ldm_frag_add function in fs/partitions/ldm.c in the Linux kernel before 2.6.39.1 does not properly handle memory allocation for non-initial fragments, which might allow local users to conduct buffer overflow attacks, and gain privileges or obtain sensitive information, via a crafted LDM partition table. NOTE: this vulnerability exists because of an incomplete fix for CVE-2011-1017.

Remediation

Check the references section for vendor advisories and patches from linux. Update linux_kernel to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
