In gst_avi_demux_riff_parse_vprp(), the number of available gst_riff_vprp_video_field_desc entries is calculated by dividing the remaining buffer size by the attacker-controlled vprp->fields value, rather than by sizeof(gst_riff_vprp_video_field_desc). This can cause the parser to treat more field descriptors as available than fit in the input buffer, resulting in out-of-bounds reads. Processing a crafted AVI via playbin/decodebin can crash the application (denial of service). Fixed upstream in gst-plugins-good 1.28.6 (GStreamer-SA-2026-0072)."}],"affected":[{"vendor":"GStreamer","product":"gst-plugins-good","versions":[{"status":"affected","version":"0","lessThan":"1.28.6","versionType":"semver"}],"packageName":"gst-plugins-good","collectionURL":"https://gitlab.freedesktop.org/gstreamer/gst-plugins-good","defaultStatus":"unaffected"},{"vendor":"Red
