Multiple authoritative sources (BleepingComputer) explicitly document this as a zero-day exploited in the wild against iPhones and Macs by NSO Group spyware, with Apple releasing emergency patches (iOS 15.0.2) to address active exploitation. The timing aligns with simultaneous patch release and exploitation disclosure, meeting zero-day criteria.
