Hi, an infinite loop in udp_v6_get_port() can be triggered and thus result in local DoS. Please see https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=170772 for a link to a patch by davem. This is CVE-2005-2973. There's also another link to a possible regression for a dst mem leak fix. Does this apply to the Debian kernel as well? Cheers, Moritz
