CVE-2026-18299 is a use-after-free vulnerability in GStreamer's rtpsbcdepay RTP SBC depayloader. While processing RTP payload elements, the component can perform operations on an object without validating that the object remains valid. A crafted RTP/SBC payload can trigger use of freed memory, potentially allowing arbitrary code execution in the context of the process using the affected GStreamer library.
