Security researchers at Alibaba's Pandora Labs have successfully jailbroken the iPhone X on iOS 11.2.1. The news comes following the group's untethered jailbreak of iOS 11.2."[Jailbreaking] is a very technical challenge and a peak for every iOS security researcher trying to climb." says Long Lei, a security researcher who has reported seven vulnerabilities to Apple.
The Apple-implemented SMAP for iOS 11.1 is flawed and can be bypassed in a certain way. However, in the latest version, this issue has been fixed, which requires safety researchers to use other ways to solve the impact of SMAP . In addition, in older versions of iOS , security researchers could also trigger the kernel GC via the mach_zone_force_gc interface, or they could only populate the same type of data. But in iOS 11 , Apple disables the mach_zone_force_gc interface, so a new way to fire the kernel GC is needed.
