Description Prasad J Pandit 2013-04-24 07:11:14 EDT 
Linux kernel built with the Virtual Socket protocol(CONFIG_VSOCKETS)
support is vulnerable to an information leakage flaw. It occurs while
receiving messages via recvmsg(2) call.

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

Upstream fix:
