CVE-2025-25468Network attack vector

Service interruption via leaked IAMF parameter allocations

Published Feb 18, 2025 · Updated Feb 19, 2025

Memory leak in FFmpeg 7.0 through 7.1 allows remote attackers to interrupt service via crafted IAMF media files. The param_parse function allocates an IAMF parameter and returns on mismatched subblock durations without freeing that allocation. Processing the crafted media requires user interaction; repeated invalid parameters consume heap memory until the FFmpeg process can no longer provide service.
