Google Researcher Releases iOS Exploit—Could Enable iOS 11 Jailbreak
As promised last week, Google’s Project Zero researcher Ian Beer now publicly disclosed an exploit that works on almost all 64-bit Apple devices running iOS 11.1.2 or earlier, which can be used to build an iOS jailbreak, allowing users to run apps from non-Apple sources.
On Monday morning, Beer shared the details on the exploit, dubbed “tfp0,” which leveraged double-free memory corruption vulnerabilities in the kernel, the core of the operating system.
While Beer says he has successfully tested his proof of concept exploit on the iPhone 6s and 7, and iPod Touch 6G, he believes that his exploit should work on all 64-bit Apple devices.
Another security researcher confirmed that the exploit released by Beer also works on his Apple TvOS 11.x and TV 4K running iOS 11.1.2.
What’s worse? Since Apple’s iOS mobile operating system and macOS desktop operating system share the same code base, the kernel for macOS is also vulnerable to the bug, according to a report published by Project Zero on Google’s Chromium Blog.
Although we have not heard any news about iOS jailbreaks from the jailbreak community from very long, Beer’s exploit could be the basis for a future iOS 11 jailbreak, allowing iPhone and iPad users to install third-party OS customizations via apps that are restricted by Apple.
If iOS 11.1.2 jailbreak surfaces in upcoming days, you can still downgrade to iOS 11.1.2 using iTunes even if you have updated to iOS 11.2 because Apple is still signing the operating system.
