Why don't wait ios13 out and A13 devices is out just release? They definitely will patch according to this

It's not like it was a particularly good bug. And it would've been obvious from the page table dump anyway, so I didn't wanna leave it unmentioned.

It seems make no sense for PPL mode, this we can use a ROP in PPL entry to switch to PPL mode. Why they design as this?

You can't though. The entry is protected by a check, and the exit isn't executable from outside. And the stack is switched to protected memory too btw.
