The iOS 15 jailbreak is currently (still) pretty quiet – but now something not insignificant has happened with the iOS 15.1 jailbreak status. Respected security expert Ian Beer posted on the Google Project Zero Blog on Friday.
First of all: There is currently (01/22/2022) no jailbreak for iOS 15.1. Ian describes a proof of concept (PoC) at the kernel level. This is the lowest level in an operating system and Ian exploits the CVE-2021-3094 vulnerability .
But what is the CVE-2021-3049 bug? The vulnerability is a bug in the main memory. This can be attacked by the bug, damaged and used for a jailbreak, among other things. The rating is 7.8/10 points and has therefore been rated as “High Risk”. Apple has fixed the vulnerability for mobile devices running iOS 15.2, iPadOS 15.2 and watchOS 8.3. Further information on the exploit is available from the US government’s official Nation Vulnerability Database , for example.
In the published article by Ian Beer, he shows his PoC using macOS, but this should also be adaptable for iOS in a similar way.
According to the iOS 15.2 changelog , Apple itself states that CVE-2021-3049 was affected on iPhones or iPads running iOS or iPadOS 15.1.1 or older:
Available for: iPhone 6s and newer, iPad Pro (all models), iPad Air 2 and newer, iPad (5th generation and newer), iPad mini 4 and newer and iPod touch (7th generation)
In view of the fact that the iOS 15 jailbreak has been a long time coming and the jailbreak community is not exactly growing, the news can be interpreted as positive.
iOS 15.1 jailbreak status
Jailbreak developers are currently waiting for an exploit that they can also work with and thus get the ball rolling. With the introduction of iOS 15, Apple introduced another security feature: secured signed system partitions (SSV – Signed System Volume). This relevant security feature is of course good for normal users, but not exactly optimal from the point of view of every jailbreak fan.
All well-known jailbreak teams already have approaches on how to bypass this “feature” and accomplish a jailbreak.
At the moment, however, it is not yet possible to say with certainty whether Ian’s PoC will facilitate a jailbreak for iOS 15.1 or not. So the current iOS 15.1 jailbreak status is: The next few weeks will definitely be exciting and we will of course keep an eye on it. Follow us on Facebook and Twitter to not miss any news.
Given that Ian’s past exploits have already been used as a basis for jailbreaks, the chances are currently quite high.
What versions will an iOS 15 jailbreak come for?
After the CVE-2021-30949 exploit is fixed with iOS 15.2, only iOS and iPadOS 15.1.1 and older will be supported. This is a good example of why you should always stay on the lowest possible iOS version.
