CVE-2022-42825

Protected filesystem modification via excess entitlements

Published Nov 1, 2022 · Updated Apr 21, 2025

An incorrect privilege assignment in Apple macOS before 13 allows local users to modify protected filesystem areas via excess entitlements. The AppleMobileFileIntegrity entitlement set grants an app additional privileges that permit writes ordinarily blocked by system protection. Exploitation requires execution of the app on the affected Apple operating system; the documented impact is filesystem integrity loss, with no evidence of network reachability or confidentiality impact.
