Even if I believe that-- and I already discussed some reasons why I shouldn't-- exploit in another layer of the stack will allow an attacker to run something different on my computer. And even if I magically was able to audit all of that software, it still wouldn't tell me anything about what software is running on, for example, my RAID card, or inside my computer mouse.
You can get closer and closer to certainty, but never reach it.
