CVE-2026-18649
CVE-2026-18649 · Gstreamer1-plugins-good: gst-plugins-good: unbounded memory growth in rtph264depay and rtph265depay rtp depayloaders
This page contains facts from public vulnerability sources. Check the original advisory before updating.
A flaw was found in the GStreamer gst-plugins-good package. The rtph264depay and rtph265depay RTP depayloader elements do not enforce a maximum size limit on the reassembly buffer used during fragmented RTP packet processing. A remote, unauthenticated attacker can send a continuous stream of RTP fragments without ever transmitting an end-of-fragment marker, causing the reassembly buffer to grow without bound until process memory is exhausted. This results in a denial of service through process termination.
