Gstreamer: gstreamer: use-after-free in gstreamer core buffer value deserialization
CVSS Score
7.5
EPSS Score
0.0%
EPSS Percentile
0th
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.
