Currently exploit not working on A7-A8 devices.
Probably heap setup is incorrect.

I was also trying this on my iPhone 6, had the same error.

I had the same issue on an iPhone 5S (iOS 12.4.5).
Can this issue be fixed or will the exploit stay unfunctional for A7-A8 ?

[krisanovdev]

@JbAmade It can be fixed if kernel bug exists on such iOS version (probably yes?). It requires some chhanges in heap setup I guess.

@Mrkris99 Thanks for your reply.
Yes, the bug exists in all iOS versions from 12.0 to 13.3. There’s probably something to fix during the heap setup for A7-A8, that’s true...

Any update on this?
