    Ah, all based on the premise you know where to find that one buggy driver. Making device nodes takes root privileges, so that one step seems to have been taken for granted, but it is not. And the problem is not the exploit, if and when it works. In 99% of cases like this, you will crash the host with kernel oops/panic.

    P.S. Nice to see people having some decent asm skills ...

    Cheers,
    Mrk
