CVE-2024-40800

Protected filesystem modification by local applications

Published Jul 29, 2024 · Updated Apr 2, 2026

Improper input validation in Apple macOS allows local applications to modify protected parts of the file system through Restore Framework. Apple has not published which Restore Framework input is accepted incorrectly or which validation check is missing. Execution requires a local application, and the bounded reported consequence is unauthorized modification of filesystem locations that macOS protects.
