CVE-2026-46472

HIGH 7.5

Published 2026-10-16 · Last modified 2026-10-16

An issue was discovered in GStreamer gst-plugins-good before 1.28.2. While parsing an MP4 file, the isomp4 plugin's qtdemux_parse_chnl function may read past the end of a global array, potentially leading to information disclosure.
