CVE-2026-18649 on CTRL-OS 26.05

Aliases: CVE-2026-18649

Packages: gst_all_1.gst-plugins-good

Status: Plausible

Advisory Information

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.
