Jailbreak iOS 12.1.1/12.1: WebKit RegEx Exploit Remote Safari Jailbreak (Update)

Lately, Apple hacker Linus Henze made WebKit RegEx Exploit, a 0-day exploit for iOS 12.1 and below, public. Please note that the bug which this exploit utilizes is fixed by Apple in the latest version of the WebKit Engine. But, this exploit still works in the latest version of mobile Safari. According to Linus Henze, all iterations of iOS 12 are vulnerable to this exploit. This WebKit Regex Exploit also works on iOS 12.1.1. However, since iOS doesn’t support shellcode loading out-of-the-box, the exploit has got no use. But, the silver lining is that Linus is pretty confident of developing shellcode loading into iOS at a later period of time.
