CVE-2019-8591

This PoC exploits a type confusion vulnerability in macOS's stf_ioctl function, where a user-provided `struct ifreq` is incorrectly cast to `struct ifaddr`, leading to a kernel panic. The exploit triggers a page fault by accessing invalid memory, demonstrating the vulnerability in macOS 10.14.3.

This is a kernel exploit for iOS 12-12.2 and 12.4, leveraging a use-after-free vulnerability (CVE-2019-8591) to achieve local privilege escalation. The exploit manipulates kernel structures to gain arbitrary read/write capabilities.
