DescriptionCVE.org

GStreamer H.266 Codec Parser Integer Underflow 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 parsing of picture partitions. The issue results from the lack of proper validation of user-supplied data, which can result in an integer underflow before writing to memory. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-28910.

AnalysisAI

CVE-2026-3084 is an integer underflow vulnerability in GStreamer's H.266 codec parser that allows remote code execution when processing malicious media files. The vulnerability affects all versions of GStreamer (CPE indicates wildcard versioning) and can be exploited through user interaction with specially crafted H.266 video content, allowing attackers to execute arbitrary code in the context of the application. No active exploitation (not in KEV) or public POC has been reported, and the relatively high CVSS score (7.8) is tempered by the local attack vector and user interaction requirement.

Technical ContextAI

GStreamer is an open-source multimedia framework widely used for building media handling components in applications. The vulnerability occurs specifically in the H.266 (Versatile Video Coding/VVC) codec parser when processing picture partitions. As a CWE-191 (Integer Underflow) vulnerability, the flaw arises from insufficient validation of user-supplied data during partition parsing, causing an integer value to wrap below its minimum value. This underflow subsequently leads to incorrect memory calculations and out-of-bounds memory writes. The affected product CPE (cpe:2.3:a:gstreamer:gstreamer:*:*:*:*:*:*:*:*) indicates all versions are potentially vulnerable until patched.

RemediationAI

Apply the patch commit available at https://gitlab.freedesktop.org/gstreamer/gstreamer/-/commit/496e4f296e658fba7fd40027d3bbe6095633ec91. Organizations should update to the latest patched version of GStreamer that includes this fix. As a temporary mitigation, disable H.266/VVC codec support in GStreamer if this functionality is not required, or implement input validation for H.266 content sources. Monitor the Zero Day Initiative advisory at https://www.zerodayinitiative.com/advisories/ZDI-26-169/ for additional updates.
