I'm not aware of that, could you file a bug until this is sorted out?
Patching udp.c:255 following to:
#endif /* SO_REUSE */
) && (inp->ip_addr.addr == pcb->local_ip.addr)) {
/* the first unconnected matching PCB */
uncon_pcb = pcb;
seems like a working short term fix.
That seems to prevent pcbs with a local IP of 'any' from receiving such
packets.
