When crafted serialized buffer data contains an invalid character, an error path frees a mapped buffer before unmapping it. An application that parses untrusted caps or structure data could crash; a network-facing GStreamer Data Protocol receiver can process such data without user interaction. Further impact has not been established.","published":"2026-11-10T11:16:43.580","modified":"2026-11-10T11:16:43.700","cvss":{"score":7.5,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":null,"references":[{"type":"WEB","url":"https://access.redhat.com/security/cve/CVE-2026-125704"},{"type":"WEB","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2569128"},{"type":"WEB","url":"https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/11583.patch"},{"type":"WEB","url":"https://gstreamer.freedesktop.org/security/sa-2026-0028.html"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-11-10T11:16:43.700"}}
