I don't remember much about my OS courses from 20 years back, but I do recall something about walls between user space and kernel space. The fact that an update from the Internet could enter kernel space is insane to me.
You mean you don’t update your kernel?
I do, but I do it on my terms when I know it is stable. I don't allow anyone to push updates to my system.
Agreed. Point is, I’m pretty sure programs in kernel space can still read stuff in user space, which can be easily updated.
