{"id":"DEBIAN-CVE-2026-125704","details":"A use-after-free flaw was found in GStreamer core buffer value deserialization. When serialized buffer text contains an invalid character, an error path frees a mapped buffer before unmapping it. Applications that parse untrusted caps or structure data can reach a freed-buffer read and may crash. A network-facing GStreamer Data Protocol receiver can process such caps data without user interaction; further impact has not been established.","modified":"2026-11-11T22:00:06.369593720Z","published":"2026-11-10T11:16:43.580Z","upstream":["CVE-2026-125704"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-125704"}],"affected":[{"package":{"name":"gstreamer1.0","ecosystem":"Debian:12","purl":"pkg:deb/debian/gstreamer1.0?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.22.0-2","1.22.0-2+deb12u1","1.22.1-1","1.22.10-1","1.22.2-1","1.22.3-1","1.22.3-2","1.22.4-1","1.22.5-1","1.22.6-1","1.22.7-1","1.22.8-1","1.22.9-1","1.23.1-1","1.23.2-1","1.23.90-1","1.24.0-1","1.24.1-1","1.24.10-1","1.24.10-2","1.24.11-1","1.24.11-2","1.24.12-1","1.24.2-1","1.24.3-1","1.24.3-1+ports","1.24.4-1","1.24.4-1+hurd.1","1.24.5-1","1.24.6-1","1.24.7-1","1.24.8-1","1.24.9-1","1.24.9-1+ports","1.25.1-1","1.25.1-2","1.25.1-3","1.25.1-4","1.25.50-1","1.25.90-1","1.25.90-2","1.26.0-1","1.26.0-2","1.26.0-3","1.26.1-1","1.26.10-1","1.26.2-1","1.26.2-2","1.26.3-1","1.26.3-2","1.26.4-1","1.26.5-1","1.26.5-2","1.26.6-1","1.26.6-2","1.26.7-1","1.26.8-1","1.26.8-2","1.26.8-3","1.26.9-1","1.27.1-1","1.27.2-1","1.27.2-2","1.27.50-1","1.27.90-1","1.27.90-2","1.28.0-1","1.28.0-2","1.28.1-1","1.28.2-1","1.28.3-1","1.28.4-1","1.28.4-2","1.28.5-1","1.28.6-1","1.28.7-1","1.28.8-1","1.28.9-1","1.29.1-1","1.29.2-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-125704.json"}},{"package":{"name":"gstreamer1.0","ecosystem":"Debian:13","purl":"pkg:deb/debian/gstreamer1.0?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.26.10-1","1.26.2-2","1.26.3-1","1.26.3-2","1.26.4-1","1.26.5-1","1.26.5-2","1.26.6-1","1.26.6-2","1.26.7-1","1.26.8-1","1.26.8-2","1.26.8-3","1.26.9-1","1.27.1-1","1.27.2-1","1.27.2-2","1.27.50-1","1.27.90-1","1.27.90-2","1.28.0-1","1.28.0-2","1.28.1-1","1.28.2-1","1.28.3-1","1.28.4-1","1.28.4-2","1.28.5-1","1.28.6-1","1.28.7-1","1.28.8-1","1.28.9-1","1.29.1-1","1.29.2-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-125704.json"}},{"package":{"name":"gstreamer1.0","ecosystem":"Debian:14","purl":"pkg:deb/debian/gstreamer1.0?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.28.3-1"}]}],"versions":["1.26.10-1","1.26.2-2","1.26.3-1","1.26.3-2","1.26.4-1","1.26.5-1","1.26.5-2","1.26.6-1","1.26.6-2","1.26.7-1","1.26.8-1","1.26.8-2","1.26.8-3","1.26.9-1","1.27.1-1","1.27.2-1","1.27.2-2","1.27.50-1","1.27.90-1","1.27.90-2","1.28.0-1","1.28.0-2","1.28.1-1","1.28.2-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-125704.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
