commitbc8d591654upstream. split_if_spec expects a NULL-pointer as an end marker for the argument list, but tuntap_probe never supplied that terminating NULL. As a result incorrectly formatted interface specification string may cause a crash because of the random memory access. Fix that by adding NULL terminator to the split_if_spec argument list.
