A malicious or\nmalformed Thunderbolt device can set dual_link_port_nr beyond the\nallocated sw->ports[] (max_port_number + 1 entries), producing an\nout-of-bounds tb_port pointer that is stored and later dereferenced.\n\nReject a port entry whose dual_link_port_nr exceeds max_port_number,\nthe same bound already applied to header->index.",
