CVE-2023-42893

Protected user data access via Libsystem permissions

Published Mar 28, 2024 · Updated Nov 4, 2025

A permissions flaw in Apple Libsystem on affected macOS, iOS, iPadOS, tvOS, and watchOS releases allows local users to access protected user data. Apple identifies Libsystem as the locus but has not disclosed which permission check was missing or how untrusted input reaches the removed code. Exploitation requires local execution and user interaction, and the documented consequence is unauthorized reading of protected user data without integrity or availability impact.
