Well you have to presume the kernel has some vulnerabilities but you can control what code calls into the kernel, at least for very early boot when the system is still being set up. Anything that has a fixed function can get signatures and be solidified, the problems come in when you have to run arbitrary code which is outside the users ability to audit.
