IOHIDFamily has been notorious in the past for the many race conditions it contained, which ultimately lead to large parts of it being rewritten to make use of command gates, as well as large parts being locked down by means of entitlements. I was originally looking through its source in the hope of finding a low-hanging fruit that would let me compromise an iOS kernel, but what I didn’t know it then is that some parts of IOHIDFamily exist only on macOS - specifically IOHIDSystem, which contains the vulnerability discussed herein.mac macos security
