When you do some bad things in your Kernel Extension (such as

It depends on what you damage. If you read/write completely out of
bounds, your code will fail. But if you destroy a pointer
belonging to someone else, there is no way for the hardware/kernel
to know a) that that's what you're doing, or b) to blame you when
some other code attempts to use it.
It turned out to be a copyin of a bigger size than required.
It could be cool if there was a Kernel simulator with memory
protection...
