It could occur when communicating over direct client-to-client IRC connection(/dcc) via a NAT-ed network. Kernel attempts to mangle IRC TCP packet's content, wherein an uninitialised 'buffer' object is copied to a socket buffer and sent over to the other end of a connection. Upstream fix: ------------- -> https://git.kernel.org/linus/2690d97ade05c5325cbf7c72b94b90d265659886 Reference: ---------- -> https://bugzilla.redhat.com/show_bug.cgi?id=1058748 Thank you -- Prasad J Pandit / Red Hat Security Response Team
