The userspace can ask kprobe to intercept strings at any memory address, including invalid kernel address.
Again, this is not about a "kernel address" at all.
It's neither a kernel address _nor_ a user address. It's an invalid address entirely, and there is nothing that makes it "kernel".
Please don't talk about "invalid kernel addresses" when it is no such thing.
