CVE-2025-24123

App termination via unchecked file parsing

Published Jan 27, 2025 · Updated Jun 2, 2026

Denial of service in Apple CoreMedia on affected iOS, iPadOS, macOS, tvOS, visionOS, and watchOS releases allows attackers to crash an app. The CoreMedia file parser applies insufficient checks to untrusted file data; Apple has not disclosed the exact parser routine or invalid field. An affected app must parse the file, and the reported consequence is app termination rather than system shutdown or code execution.
