CVE-2011-2182

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.

CWE-119 Improper Restriction of Operations within the Bounds of a Memory Buffer

The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
