QUESTION

What would be the best approach patch-finding the pointer of a certain function on the XNU Kernel?

Asked 2020-Dec-31 at 16:55

I am currently working on an iOS Jailbreak for iOS 13.7. As part of the jailbreak, I need to do a series of patches to the XNU Kernel live in the memory. Of course, the kernel is protected by kASLR, KPP / KTRR, and other memory watchdogs that would trigger a Kernel Panic if something is modified. As luck would have it, KTRR (Kernel Text Ready Only Region) can only protect, well, static data that is not supposed to change (i.e. the TEXT section and constants). The variables can still be altered.

I am building a PatchFinder which is supposed to locate a function or a variable in the XNU memory based on tell-tale symbols and I am wondering what would be the most effective approach for this.

I am currently adapting on top of the PatchFinder made publicly available back in the iOS 8 era by in7egal which looks like this:
