Summary

Gatekeeper auth token key compromise

Details

In TBD of keymaster_ipc.cpp, there is a possible to force gatekeeper, fingerprint, and faceauth to use a known HMAC key. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.
