GStreamer 1.28.4 GstVideoMeta Heap Buffer Overflow

GStreamer version 1.28.4 contains a heap buffer overflow in libgstvideo when untrusted GstVideoMeta data is deserialized through unixfd. The included proof of concept causes a stock receiver pipeline to read outside the backing frame buffer. https://packetstorm.news/download/237272...

CVE-2026-86476

A flaw was found in gst-plugins-base. A heap buffer overflow can be triggered when processing video buffers whose attached GstVideoMeta metadata declares plane strides and offsets that exceed the actual backing memory allocation. The metadata is not range-checked during deserialization, and the...
