Description Agostino Sarubbo gentoo-dev 2013-12-01 09:13:50 UTC
From ${URL} :

Linux kernel built with the networking support(CONFIG_NET), is vulnerable to a
memory leakage flaw. It occurs while doing the recvmsg(2), recvfrom(2),
recvmmsg(2) socket calls.

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