Following the release of iOS 12.1.3, iOS hacker @S0rryMyBad has released his iOS 12.1.2 exploit. The hacker had discovered this exploit a few weeks ago and announced that he will release it after it has been patched by Apple in the next release, and today he has done exactly that.
In a tweet hacker sent through his account he showed the proof of concept of the bug he used to jailbreak iOS 12.1.2 on pre-A12 chip devices. In the same tweet he has mentioned that he will share more details on A12 devices in a blog post, which we are surely looking forward to.
What makes @S0rryMyBad’s exploit special is the fact that it is able to achieve tfp0, which is essentially a kernel task port that allows read and writes to handset’s kernel memory. This type of access can be instrumental in the development of an iOS 12 jailbreak.

With this exploit’s availability it is not far-fetched to think about an iOS 12 jailbreak’s sooner than later release, however it will still be foolish to think of an early ETA for it. There’s still a lot of work that needs to be completed before a jailbreak is ready for public release, that too provided if someone is willing to put in the work in the first place.
While the release of iOS 12.1.2 exploit is a great news for those who had upgraded to iOS 12, those who are on iOS 11 and jailbroken should stay where they are as there are no guarantees if we will see an iOS 12 jailbreak release or not.
