It has been committed: gcc+glibc will now warn if a user uses a NULL
argv array in an execv* call or a NULL argv[0] in an execl* call.

But the gcc warnings can cover only 7 out of 11 cases. Therefore the kernel
behaviour is more important. Is there anyone who could help out and test the
proposed Linux kernel patch?
