CVE-2012-5375

Published: 18 February 2013

The CRC32C feature in the Btrfs implementation in the Linux kernel before 3.8-rc1 allows local users to cause a denial of service (prevention of file creation) by leveraging the ability to write to a directory important to the victim, and creating a file with a crafted name that is associated with a specific CRC32C hash value.

From the Ubuntu Security Team

A denial of service flaw was discovered in the Btrfs file system in the Linux kernel. A local user could cause a denial of service (prevent file creation) for a victim, by creating a file with a specific CRC32C hash value in a directory important to the victim.
