reached from the no-association lookup path, from_addr_param() then\nreads uninitialized bytes past the parameter.\n\nImpact: an unauthenticated SCTP peer makes the receive path read up to 16\nbytes of uninitialized memory past a truncated ASCONF address parameter.\n\nThe sibling __sctp_rcv_init_lookup() bounds parameters with\nsctp_walk_params();
