In the Nikon metadata tag parser, a pointer can be dereferenced without verifying that data remains in the buffer, causing out-of-bounds reads. Because avidemux is auto-plugged by playbin, decodebin, and gst-discoverer, opening or previewing a crafted AVI is sufficient to trigger the issue. Fixed upstream in gst-plugins-good 1.28.6 (GStreamer-SA-2026-0072).","cvssScore":6.1,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:H","cwes":["CWE-125"],"vendors":[],"products":[],"references":[{"url":"https://access.redhat.com/security/cve/CVE-2026-73471","tags":[]},{"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2514821","tags":[]},{"url":"https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/12231","tags":[]},{"url":"https://gstreamer.freedesktop.org/security/sa-2026-0072.html","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
