CVE-2025-43243

Protected filesystem modification via incorrect Software Update permissions

Published Jul 29, 2025 · Updated Apr 2, 2026

Incorrect permissions in Software Update in Apple macOS allow local users to modify protected parts of the file system. Apple identifies the faulty locus only as Software Update and states that additional permission restrictions correct the operation; no file, function, or faulty permission check is public. Execution of an app on an affected Mac is required, and the documented consequence is limited to unauthorized modification of protected filesystem areas.
