EPSS: 0.4% probability of exploitation in the next 30 days
Public exploit or detection template: none known
Published: 2012-06-13 · updated 2026-06-16
Weakness: CWE-119

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.

Affected products

Linux kernel: through 2.6.39; 2.6.39-rc1, 2.6.39-rc2, 2.6.39-rc3, 2.6.39-rc4, 2.6.39-rc5, 2.6.39-rc6 (+1)
