cve-program · CVE-2026-125704
PublishedA use-after-free flaw was found in GStreamer core buffer value deserialization. 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.
