gst-plugins-bad1.0: A flaw was found in the GStreamer gst-plugins-bad package
CVE-2026-12891 is fixed in 2 products on 1 platform, first by OPENSUSE-SU-2026:21370-1, released July 18, 2026. It is not reported as exploited. Patch Radar priority: Routine.
A flaw was found in the GStreamer gst-plugins-bad package. When processing a malformed H.266/VVC video stream with a crafted aspect ratio indicator value, the H.266 parser performs an out-of-bounds read of up to 8 bytes from adjacent memory. This flaw allows an attacker to craft a malicious H.266 video file or stream that, when processed by a GStreamer-based application, could leak limited memory contents through video metadata, potentially exposing sensitive information from the application's address space.
