UBUNTU-CVE-2026-3083: High severity ubuntu/gst-plugins-good1.0 vulnerability
GStreamer rtpqdm2depay Out-Of-Bounds Write 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 X-QDM RTP payload elements. When parsing the packetid element, the process does not properly validate user-supplied data, which can result in a write past the end of an allocated array. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-28850.

Frequently Asked Questions
What must an attacker do to exploit this issue?
An attacker must cause an affected application to process RTP payload data containing X-QDM elements. Exploitation requires user interaction with the library, although the exact delivery vector depends on how the application implements GStreamer.
What impact could exploitation have?
A successful exploit can execute arbitrary code in the context of the current process. The reported severity vector indicates high impact to confidentiality, integrity, and availability.
Which component should be checked during triage?
Check Ubuntu systems using the gst-plugins-good1.0 package, specifically applications that process RTP streams with the rtpqdm2depay element. The vulnerable parsing occurs when handling the packetid element in X-QDM RTP payloads.
