iOS 11.4 patched kernel memory corruption bugs I reported in two distinct areas: mptcp and vfs. My exploit for the mptcp bug is here: Please read the README. It requires an Apple developer cert.

That is the same bug as already publicly documented from the patch by and exploited by , see John's repo here:

The vfs bug doesn't require an Apple developer cert but is considerably harder to exploit. You get to write 8 NULL bytes off the end of a kalloc.16 buffer. It's sufficiently hard to exploit that it's worth trying just to demonstrate that such issues are reliably exploitable...

see eg The Poisoned Nul Byte, 2014 by . But it takes time. The mptcp exploit is mostly recycled bits of earlier exploits. The getvolattrlist bug needs some new techniques.

The trigger is here: If you're in to iOS exploit dev take a go at it and blog about it! I'll publish what I have soon, hopefully this week.

Finally: always keep your personal iOS devices up to date and only use these tools on devices which don't have any personal information and are only used for research.

(footnote: for the vfs bug technically you can control a handful of bits in the 8 overflow bytes, the overflow value is actually two 4 byte flag fields. This may or may not help.)
