The FLV media demuxer does not properly validate buffer sizes and data availability when processing enhanced audio and video tags in malformed or truncated FLV streams. A remote attacker could exploit this vulnerability by providing a specially crafted FLV media file that, when opened or streamed by a GStreamer-based application, triggers an assertion failure or a process crash, leading to denial of service.","cvssScore":6.5,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H","cwes":["CWE-617"],"vendors":[],"products":[],"references":[{"url":"https://access.redhat.com/security/cve/CVE-2026-119843","tags":[]},{"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2564182","tags":[]},{"url":"https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/11244.patch","tags":[]},{"url":"https://gstreamer.freedesktop.org/security/sa-2026-0020.html","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
