Subject: veth: Enforce minimum size of VETH_INFO_PEER
From: Thomas Graf <[email protected]>
[ Upstream commit 237114384ab22c174ec4641e809f8e6cbcfce774 ]
VETH_INFO_PEER carries struct ifinfomsg plus optional IFLA
attributes. A minimal size of sizeof(struct ifinfomsg) must be
enforced or we may risk accessing that struct beyond the limits
of the netlink message.
