CVE-2014-8172 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2014-8172): The filesystem implementation in the Linux kernel before 3.13 performs certain operations on lists of files with an inappropriate locking approach, which allows local users to cause a denial of service (soft lockup or system crash) via unspecified use of Asynchronous I/O (AIO) operations.
Fix in 3.13, https://github.com/torvalds/linux/commit/eee5cc2702929fd41cce28058dc6d6717f723f87
