If you have been hoping for an iOS 12 jailbreak, the latest development in the iOS jailbreaking scene might get you excited. A powerful iOS and macOS sandbox escape has been discovered which affects all iPhones and iPads running iOS 12 – iOS 12.1.
The sandbox escape can be possibly used for a potential iOS 12 jailbreak. The bug is in Apple’s QuartzCore a.k.a CoreAnimation framework which is available for both macOS and iOS. The framework primarily deals with all Core Animation functionality of the OSes.

Below is how the vulnerability has been described by the SecuriTeam.
The root cause of this vulnerability lies in QuartzCore`CA::Render::InterpolatedFunction::InterpolatedFunction function, this function does not notice the case of integer overflow.
The sandbox escape is powerful enough to launch Pangu’s IOHID exploit which in turn can lead to an iOS 12 jailbreak.
You should not really get your hopes too high about a potential iOS 12 – iOS 12.1.1 jailbreak. In theory, this sandbox escape can be used for an iOS 12 jailbreak. However, if any developer or any renowned jailbreaking team is going to take all that trouble to release an iOS 12 jailbreak is something that’s difficult to say.
Over the last couple of years, jailbreak tools for the latest iOS version were released towards the end of the year. And so there’s always a chance of something similar playing out this year as well. Or at least we can hope for one.
If your iPhone is currently running a jailbroken build of iOS 11 and you value it, you should stick to your current set up instead of upgrading to iOS 12 in hopes of a possible jailbreak release.
