If you configure a route with multiple labels, e.g. ip route add 10.10.3.0/24 encap mpls 16/100 via 10.10.2.2 dev ens4 A warning is logged: kernel: [ 130.561819] netlink: 'ip': attribute type 1 has an invalid length. This happens because mpls_iptunnel_policy has set the type of MPLS_IPTUNNEL_DST to fixed size NLA_U32. Change it to a minimum size. nla_get_labels() does the remaining validation.
