CVE-2024-55069Network attack vector

Application crash via invalid IAMF ambisonics mode

Published May 2, 2025 · Updated May 12, 2025

Null-pointer dereference in the IAMF demuxer in FFmpeg 7.1 allows remote attackers to crash applications via crafted IAMF streams. The ambisonics_config parser accepts mode values above 1 without initializing any layer, and iamf_read_header then dereferences layer 0. The application must process attacker-controlled IAMF input; exploitation interrupts the affected process, with no demonstrated data access or code execution.
