The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. Impacted is availability. The summary by CVE is:

The pipe_fcntl function in fs/pipe.c in the Linux kernel before 2.6.37 does not properly determine whether a file is a named pipe, which allows local users to cause a denial of service via an F_SETPIPE_SZ fcntl call.

The issue has been introduced in 03/20/2006. The weakness was released 01/25/2011 (oss-sec). It is possible to read the advisory at openwall.com. The identification of this vulnerability is CVE-2010-4256 since 11/16/2010. The exploitation is known to be easy. Attacking locally is a requirement. No form of authentication is needed for a successful exploitation. Technical details as well as a public exploit are known.
