NVD Description

Note: Versions mentioned in the description apply only to the upstream ocfs2-2.6.18-274.18.1.0.1.el5 package and not the ocfs2-2.6.18-274.18.1.0.1.el5 package as distributed by Oracle. See How to fix? for Oracle:5 relevant fixed versions and status.

The journal_unmap_buffer function in fs/jbd2/transaction.c in the Linux kernel before 3.3.1 does not properly handle the _Delay and _Unwritten buffer head states, which allows local users to cause a denial of service (system crash) by leveraging the presence of an ext4 filesystem that was mounted with a journal.
