CVE-2011-1163

Publication date 9 April 2011

Last updated 24 July 2024

Ubuntu priority

Low

Why this priority?

The osf_partition function in fs/partitions/osf.c in the Linux kernel before 2.6.38 does not properly handle an invalid number of partitions, which might allow local users to obtain potentially sensitive information from kernel heap memory via vectors related to partition-table parsing.

From the Ubuntu Security Team

Timo Warns discovered that OSF partition parsing routines did not correctly clear memory. A local attacker with physical access could plug in a specially crafted block device to read kernel memory, leading to a loss of privacy.
