Description Prasad J Pandit 2013-03-16 04:47:54 EDT 
Linux kernel built with Datagram Congestion Control Protocol(DCCP) with
the TCP-Friendly Rate Control(TRFC) mechanism is vulnerable to an information
leakage flaw. It occurs while doing an getsockopt call on the CCID3 socket.

A user/program could use this flaw to leak kernel memory bytes.
