**Name of the Vulnerable Software and Affected Versions** Linux kernel versions prior to 3.1.9 **Description** The issue is caused by an integer overflow in the `xfs acl from disk` function, which can lead to a heap-based buffer overflow when a local user interacts with a filesystem containing a malformed ACL, resulting in a denial of service (panic). **Recommendations** For Linux kernel versions prior to 3.1.9, update to version 3.1.9 or later to resolve the issue.
