 if (packet->key_id_mode == KEY_ID_MODE_KEY_EXPLICIT_8) {
          packet->key_source.addr64 = tvb_get_ntoh64(tvb, offset);
          proto_tree_add_uint64(field_tree, hf_ieee802154_aux_sec_key_source,
tvb, offset, 8, packet->key_source.addr64);
          proto_item_set_len(ti, 1 + 8);
          //offset += 4; // original

           offset += 8; // Raka...
        }

Offset should be +8 not +4 as in the code
