Latest update: Recently some users sent us feedback that Cox confirmed on twitter that the exploit isn't going to be useful for jailbreaking, we misunderstand on the previous news.

iOS 11.2.2 Jailbreak Update: Kernel Exploit Could Lead to an Untethered Jailbreak

Yesterday we have posted jailbreak update on iOS 11.2.1. But if you’re on iOS 11.2.2, then jailbreakers should stay where you are, as Russ Cox of Google who has been credited with a kernel exploit that has been patched in iOS 11.2.5 has indicated that he plans to release it.

Here are the details about the kernel exploit from the security content of iOS 11.2.5 which has been credited to Cox:

A kernel level exploit could mean that it could be used to develop an untethered jailbreak for iOS 11.2.2. The Electra Jailbreak tool and LiberiOS jailbreak are semi-untethered jailbreaks. A semi-untethered jailbreak is similar to an untethered jailbreak, it gives the ability to reboot your iOS device on its own. On each boot, the iOS device startup sequence is unmodified and it boots into its original, non-jailbroken state. However, instead of needing to use a tool from a computer to re-jailbreak the iOS device again, like a tethered or semi-tethered cases, the user can re-jailbreak their device with the help of an app running on the iOS device. In the case of untethered, the iOS device will retain the jailbreak state even after a reboot. Kernel exploits are very rare. Pangu jailbreak for iOS 9 was the last untethered jailbreak, so an untethered iOS 11.2.2 – iOS 11 jailbreak would be great news for jailbreakers.

Cox has confirmed that he will share the link when he releases details of the kernel exploit when he was asked if he will release the kernel bug on Twitter. Before you get too excited, it would still need time for someone to create a jailbreak tool using the kernel exploit. The kernel exploits works across all iOS 11 compatible devices, so if a jailbreak is released, it should be available for iPhone 5s and later, iPad Air and later, and iPod touch 6th generation.

One of the golden rules of jailbreaking is to stay where you are and avoid upgrading to the latest iOS software update to improve your chances of a jailbreak. If you have upgraded to iOS 11.2.5 update, then you still have a chance to downgrade down to iOS 11.2.2 as Apple is still signing the iOS 11.2.2.

Coolstar had also confirmed that most of the patches in Electra Jailbreak tool work on iOS 11.2.x.

If you’re on iOS 11.1.2 or lower, then you can use Electra Jailbreak tool or LiberiOS jailbreak to jailbreak your iPhone, iPad or iPod touch.

As always, we’ll let you know as soon as we’ve any further updates.
