Denial-of-service via MobileStorageMounter type confusion
Published Sep 15, 2025 · Updated Sep 15, 2025
Type confusion in MobileStorageMounter in Apple operating systems allows local users to cause a denial-of-service through an app. MobileStorageMounter accesses a memory resource using an incompatible type, but Apple has not disclosed the affected routine or attacker-controlled object. Exploitation requires local app execution and user interaction and can interrupt availability; no confidentiality or integrity impact is reported.
