9.8 CRITICAL

Published 2026-10-21 · Updated 2026-10-23

AI risk analysis

Summary: A heap-based buffer overflow in GStreamer's rtpL16depay element allows remote attackers to execute arbitrary code by sending malformed RTP payloads with insufficiently validated length fields.
Exploitability: Exploitation requires network access to a service that processes RTP streams through the vulnerable GStreamer component; no authentication or user interaction is needed.
Blast radius: Successful exploitation grants full control of the affected process, potentially enabling full system compromise if the application runs with elevated privileges or handles sensitive data.
Detection: No reliable host or network indicator is derivable from the published description.
Prioritized remediation: Upgrade to GStreamer version 2.590 or later, which includes a fix for this vulnerability (ZDI-CAN-31143).

NVD description

GStreamer rtpL16depay Heap-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of GStreamer. Interaction with this library is required to exploit this vulnerability but attack vectors may vary depending on the implementation. The specific flaw exists within the processing of RTP payload elements. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a heap-based buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-31143.
