CVE-2023-37448

Restricted-content disclosure via lock-screen state confusion

Published Sep 26, 2023 · Updated Nov 4, 2025

Information disclosure in Apple macOS before 14 allows local users to view restricted content from the lock screen of a Mac. The Power Management lock-screen logic maintains an incorrect state that exposes content intended to remain restricted while the session is locked. Exploitation requires local access to a locked Mac and is limited to viewing restricted content, with no reported modification or service interruption.
