**Name of the Vulnerable Software and Affected Versions** Linux kernel versions prior to 3.0 **Description** The issue allows local users to cause a denial of service, resulting in a system crash. This can be achieved through vectors involving ext4 umount and mount operations, specifically when extent splitting occurs without marking the modified extent as dirty. **Recommendations** For versions prior to 3.0, update to version 3.0 or later to resolve the issue.
