"So- apple killed both of my jailbreak chains. gasgauge was in one", tweeted Todesco.
Dubbed 'GasGauge', the double free race condition exploit needs a sandbox escape and any uid. It gives you arbitrary alloc and free primitives.
"iOS 10 went hard on security", says Todesco. "Basically all the techniques I relied on are broken. Need to start from scratch."
While this exploit isn't a full jailbreak release, it could be used by another developer to produce a jailbreak for those on iOS 9.3.3b or lower.
"I hope it makes anyone realize how hard it actually is to pull this stuff on, considering it's just 1/4th of the deal. Respect devs."
