CVE-2011-0463: Canonical Ubuntu Linux

Low severity, CVSS 2.1. EPSS: 0.5% chance of exploitation in the next 30 days.

The ocfs2_prepare_page_for_write function in fs/ocfs2/aops.c in the Oracle Cluster File System 2 (OCFS2) subsystem in the Linux kernel before 2.6.39-rc1 does not properly handle holes that cross page boundaries, which allows local users to obtain potentially sensitive information from uninitialized disk locations by reading a file.

Affected products

• Canonical Ubuntu Linux: version 8.04 only
• Linux Linux Kernel: up to and including 2.6.38.2
