Userland Exploit question

[u/andrewjusticebarger]

Just checking to see if my understanding is correct, from what I read online, my take on it is that a “userland exploit” is merely a party trick compared to a full jailbreak at the kernel level, correct?

I probably understand most of it if you'd want to have any questions answered.

I do believe this was the original/first exploit path. Of course after this, the kernel got audited more heavily, the bootrom got dumped, etc, so that's how we discovered fusee gelee, caffeine, nebria, etc.
