The check compared bLength against (size - sizeof(descriptor)), which is an absolute limit unrelated to the current buffer position. Since bLength is uint8_t (max 255), this can never exceed size - 9 for any realistic input, making the check dead code. Use (size - pos) instead so the check actually catches descriptors that extend past the end of the read data. Fixes: https://github.com/systemd/systemd/issues/41570
