Hi syzbot maintainers,

Thanks for the report.

You're getting into the kernel via generic netlink receive, so just as
an FYI - the generic netlink numbers aren't stable across systems, so
your reproducer has a quite good chance of not working without your
kernel .config and (virt) hardware environment.

I'll take a look at this and the rfkill one, I assume that there are
some sanity checks missing in hwsim generic netlink when it builds a
radio struct.

However, I can't really promise that I'll be able to validate the
changes against your reproducer.
