The golden period is going on for jailbreak enthusiasts who are eagerly waiting for a full-fledged jailbreak for iOS 12 and its subsequent versions. Qixun Zaho (@S0rryMybad) of Qihoo 360 Vulcan Team demos jailbreak of the latest iOS 12 on iPhone X with a working terminal at the Tianfu Cup PWN Contest held in November last year. With the aid and assistance of a type confusion Jit Bug in Safari Browser and a UaF bug in iOS kernel, he was able to gain complete jailbroken access on iPhone X. Lately, he has posted a proof of concept (PoC) of the exploit for iOS 12-12.1.1.
The news has spread a wave of happiness in the jailbreak community as they are sighting a jailbreak to come up soon for iOS 12-12.1.1 in very near future. @pwn20wnd has recently released the Beta 5 for UnC0ver V 2.2.0 and tested @S0rryMybad PoC Code on iOS 11, wherein he has confirmed the existence of the bug. @pwn20wnd was quick to add that updating UnC0ver for iOS 11.4 and iOS 11.4.1 will be the matter of adding the new kernel exploit that provides a clean kernel task port.

@pwn20wnd also stated that the iOS users who are on iOS 11.4-11.4.1 must stay on the same iOS operating system and should not upgrade to iOS 12. This is because, as mentioned above, updating UnC0ver Jailbreak for iOS 11.4-11.4.1 will be easy and simple with the aid and assistance of the kernel vulnerability detected by @S0rryMybad. However, as far as iOS 12 is concerned, it will require multiple jailbreak patches to be updated and new patches to be written so it might take a considerable amount of time.

Finally, the possibility of iOS 12-12.1.1 jailbreak coming out soon cannot be ruled out.
