Privilege escalation via AVEVideoEncoder out-of-bounds write
Published Mar 18, 2022 · Updated Aug 3, 2024
Out-of-bounds write in Apple AVEVideoEncoder before 15.4 allows local users to gain elevated privileges on iOS, iPadOS, and tvOS. Apple identifies the faulty operation as a write beyond bounds but has not disclosed the affected function, buffer, or malformed encoder input. Execution of a local application is required, and successful exploitation elevates that application's privileges without a reported remote attack path.
