Also, it's less about "their" drivers and more about what a kernel module can do.
Saying "there's no way to know" doesn't fit, because we do know that a malformed kernel module can destabilize a linux or mac system.
"Malformed file" isn't a programming defect or something you can fix by having a better API.
Having the data exposed to userspace via an API would avoid having to have a kernel module at all... Which when malformed wouldn't compromise the kernel.
I mean, sure. But typically operating systems don't expose that type of information to user space, instead providing a kernel interface with user mode configuration.
It's why they use the same basic approach on mac and Linux.
