CVE-2023-42835

User-data disclosure through undisclosed logic error

Published Feb 21, 2024 · Updated Nov 4, 2025

Information disclosure in RemoteViewServices in Apple macOS before 14.1 allows local users to access sensitive user data. Apple states only that an unspecified logic issue in RemoteViewServices performed inadequate checks; no affected operation or input has been disclosed. Reachability requires local low-privileged access, and the documented consequence is limited to reading user data rather than modifying it or interrupting the system.
