Description Prasad Pandit 2013-04-24 10:03:11 UTC
Linux kernel built with the NETROM virtual network devices (CONFIG_NETROM)
support are vulnerable to an information leakage flaw. It occurs while
receiving messages via recvmsg(2) socket call.

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