**Name of the Vulnerable Software and Affected Versions** Linux kernel versions prior to 3.8-rc1 **Description** The issue allows local users to cause a denial of service, resulting in extended runtime of kernel code. This is achieved by creating many different files whose names are associated with the same CRC32C hash value, exploiting the CRC32C feature in the Btrfs implementation. **Recommendations** For Linux kernel versions prior to 3.8-rc1, update to version 3.8-rc1 or later to resolve the issue.

**Name of the Vulnerable Software and Affected Versions** Linux kernel versions prior to 3.8-rc1 **Description** The issue allows local users to cause a denial of service by preventing file creation. This is achieved by writing to a directory important to the victim and creating a file with a crafted name associated with a specific CRC32C hash value. **Recommendations** For versions prior to 3.8-rc1, update to version 3.8-rc1 or later to resolve the issue.
