Insufficient validation of attacker-controlled length and size values can bypass bounds checks and cause out-of-bounds heap reads. This can result in application crash, denial of service, or limited information disclosure when untrusted media is processed.","published":"2026-08-10T03:16:40.380","modified":"2026-08-10T03:16:40.380","cvss":{"score":7.1,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":null,"references":[{"type":"WEB","url":"https://access.redhat.com/security/cve/CVE-2026-19389"},{"type":"WEB","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2513016"},{"type":"WEB","url":"https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/12233"},{"type":"WEB","url":"https://gstreamer.freedesktop.org/releases/1.28/"},{"type":"WEB","url":"https://gstreamer.freedesktop.org/security/sa-2026-0075.html"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-08-10T03:16:40.380"}}
