The MacDirtyCow bug, also known as CVE-2022-46689, has opened Pandora’s box for Apple on iOS & iPadOS 15.x-16.1.2 because it allows people to make system customizations on their non-jailbroken iPhones and iPads that they technically shouldn’t be allowed to make. It all works by sideloading a special app that exploits this bug.
App developers can make special sideloadable apps that take advantage of the MacDirtyCow bug on iOS 16.0-16.1.2 and iPadOS 15.0-15.7. Apps that exploit this bug can make cosmetic and functional changes to the operating system if it’s within the bounds of memory that a sandboxed app can access.
