V0rtex

v0rtex is a software exploit in IOSurface written by Siguza, based on vulnerabilities discovered by white-hat hacker Ian Beer of the Google Zero project. It covers all versions of iOS 10, whereas Beer’s own async_wake exploit covers 11.0-11.1.2.

The v0rtex exploit proved to be suitable for jailbreaks, and powers two jailbreak projects: Saïgon (ARM64), where it replaced the ziVa exploit, and h3lix (ARMv7s). iOS 10.3.3 is the final version for all A6 devices, and also an OTA signed version for some A7 devices, making both jailbreaks extra relevant.
