CVE-2017-13868

This exploit leverages a kernel heap information leak in macOS High Sierra (CVE-2017-13868) by exploiting a race condition in the `ctl_ctloutput()` function, which fails to check the return value of `sooptcopyin()`. This allows uninitialized kernel heap data to be leaked to user space via a crafted `getsockopt()` call on a kernel control socket.

This PoC exploits CVE-2017-13868, a kernel heap information leak in macOS High Sierra 10.13 and iOS 10.1.1, by leveraging a race condition in the `ctl_ctloutput` function to leak uninitialized kernel heap data to user space. The exploit requires root privileges and demonstrates the vulnerability by triggering a race between memory allocation and copy operations.
