CVE-2022-42838

Camera video disclosure via stale extension access

Published Feb 27, 2023 · Updated Mar 11, 2025

Improper resource lifecycle handling in CoreMedia in Apple macOS before 13 allows local users to retain access to camera video. A camera extension continues receiving the video stream after the activating app closes because CoreMedia fails to revoke camera-data access at the end of the app session. The attacker must run a camera extension with app-granted camera access, and the documented consequence is continued video capture after that app exits.
