Original Sploit: https://bugs.chromium.org/p/project-zero/issues/detail?id=1417#c3 CJI patch: https://gist.github.com/cji/32498b19ca0bf0536f5f40cc9b0881cc.

Used @cji's great blog-post to extract these: https://medium.com/@cji_/hunting-for-ios-kernel-symbols-e48a446bb00

Turns out that the iPhone6 and iPod6g symbols are the same... I thought 16 of the 18 were identical. Tried running the exploit against the iphone6 using the ipod6g symbols and managed to hit the 1/10 times this sploit fails. So I stuck to my working symbols. My symbols got you tfp0 but the debugger wasn't working. I recalculated and found that actually 18/18 symbol locations are identical between the two devices.

So you can actually just change the detection string for iPhone6 to this:

 printf("this is iPhone 6s, should work!\n");
     symbols = ksymbols_ipod_touch_6g_15b202;
     have_syms = 1;
