CVE-2026-46469

Application crash via zero-channel MP4 audio track

Published May 14, 2026 · Updated May 14, 2026

Division by zero in GStreamer Good Plug-ins before 1.28.2 allows attackers to crash an application via a crafted MP4 audio track. In the isomp4 qtdemux_parse_trak function, a zero audio-channel count from MP4 atom data reaches a division operation without a nonzero check. The affected plug-in must parse attacker-controlled MP4 content, and exploitation interrupts only the hosting application without reported data access or modification.
