CVE-2024-40811

Protected-filesystem modification via undisclosed sudo checks

Published Jul 29, 2024 · Updated Apr 2, 2026

Improper permission preservation in sudo in Apple macOS before 14.6 allows local users to modify protected filesystem areas. Apple identifies improved checks as the correction but has not disclosed the affected sudo operation or its handling of application-controlled input. Execution of a local application is required, and successful exploitation permits writes to filesystem locations normally protected from that application.
