s->setup_len and s->setup_index are fed into usb_packet_copy as size/offset into s->data_buf, it's possible for invalid state to exploit this to load arbitrary data. An user able to alter the savevm data (either on the disk or over the wire during migration) could use this flaw to to corrupt QEMU process memory on the (destination) host, which could potentially result in arbitrary code execution on the host with the privileges of the QEMU process.
