Apple released iOS 15.4 beta 5 yesterday, it’s already been replaced some iOS bugs. The famous iOS exploit developer @realBrightiup was found two XNU bugs fixed in iOS 15.1, and he shared them with the jailbreak community.
After a few days ago he will publish the POC (proof of concept) that can be jailbreak developers to use.
But according to other exploit developers, it is not a POC, but anyway another developer Jake James who is the developer of the rootless jailbreak tool he is made a real POC using the Brightups exploit document.
And also (Jake James) twitted he is also working on his own kernel exploit, he will try to make it clean and usable for a public jailbreak.
This means that developers of popular jailbreak tools such as unc0ver and Taurine can use this stable exploit to update their jailbreak tools’ compatibility to iOS 15 – iOS 15.1 support.
