CVE-2025-43349

App termination via crafted video processing

Published Sep 15, 2025 · Updated Sep 15, 2025

Out-of-bounds write in CoreAudio in Apple operating systems before the listed fixes allows local users to terminate an app via a crafted video file. CoreAudio writes beyond a buffer while processing invalid video data; Apple has not disclosed the affected parser, field, or destination buffer. Exploitation requires local low-privileged access and user interaction, and the documented consequence is application termination only.
