GStreamer H.266 Codec Parser Stack-based Buffer Overflow Remote Code Execution Vulnerability

GStreamer contains a remote code execution vulnerability (CVE-2026-3081) rated 7.8 CVSS that allows attackers to execute arbitrary code if they can interact with the library through an affected application. The severity and attack vector depend on how individual applications implement GStreamer, meaning the risk level varies across different deployments. Security teams should prioritize patching GStreamer and applications using it, and evaluate their specific implementations to determine exposure and deployment urgency.
