ZDI-26-165: GStreamer RealMedia Demuxer 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 ZDI has assigned a CVSS rating of 7.8. The following CVEs are assigned: CVE-2026-2922.
AI Analysis
Technical Summary
CVE-2026-2922 is a critical remote code execution vulnerability in the GStreamer RealMedia Demuxer caused by an out-of-bounds write. The root cause is insufficient validation of user-supplied data during video packet processing, leading to a write beyond the allocated buffer. Exploitation requires interaction with the GStreamer library, and successful exploitation enables arbitrary code execution in the context of the current process. The Zero Day Initiative assigned a CVSS score of 7.8 and coordinated public disclosure on March 6, 2026. GStreamer has released an official patch to remediate this vulnerability.
Potential Impact
Remote attackers can exploit this vulnerability to execute arbitrary code on affected systems running vulnerable versions of GStreamer. This can lead to full compromise of the affected process, including potential control over the host system depending on the context in which GStreamer is used.
Mitigation Recommendations
An official patch has been released by GStreamer to correct this vulnerability. Users and administrators should apply the update referenced at https://gitlab.freedesktop.org/gstreamer/gstreamer/-/commit/88df8d2cd063b95a076e8041b47f778a4402f363 to mitigate the risk. No additional mitigation steps are indicated by the vendor advisory.
