CVE-2026-2922 — GStreamer RealMedia Demuxer Out-Of-Bounds Write Remote Code Execution Vulnerability

Description (CNA)

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 specific flaw exists within the processing of video packets. The issue results from the lack of proper validation of user-supplied data, which can result in a write past the end of an allocated buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-28845.

A flaw was found in GStreamer. This vulnerability allows a remote attacker to execute arbitrary code by exploiting an out-of-bounds write in the RealMedia Demuxer component. The issue occurs due to improper validation of user-supplied data during the processing of video packets, leading to a write past the end of an allocated buffer. Successful exploitation can result in arbitrary code execution within the context of the current process.
