CVE-2025-31233Network attack vector

App termination and process-memory corruption via video parsing

Published May 12, 2025 · Updated Apr 2, 2026

Improper input validation in CoreMedia across affected Apple platforms allows attackers to crash apps or corrupt process memory via crafted video files. The parser accepts insufficiently sanitized video input, but Apple has not disclosed the specific field, validation failure, or memory operation involved. The file must reach CoreMedia processing; the documented consequence is app termination or process-memory corruption, with no published claim of code execution.
