CVE-2016-7661

This exploit leverages a Mach port deallocation vulnerability in powerd (CVE-2016-7661) by spoofing a MACH_NOTIFY_DEAD_NAME message to force the privileged process to drop a reference on an attacker-controlled Mach port, potentially leading to privilege escalation.

This exploit targets a race condition in the `set_dp_control_port` MIG method in macOS/iOS kernels, allowing root-to-kernel privilege escalation. The PoC demonstrates a race condition leading to a use-after-free or reference count manipulation, enabling arbitrary kernel memory manipulation.
