CVE-2026-125041
Gst-plugins-good: gst-plugins-good: qtdemux out-of-bounds heap read from invalid uncompressed video layout
Description
A flaw was found in GStreamer's gst-plugins-good MOV/MP4 demuxer. When processing an uncompressed video track, qtdemux fails to validate the declared row alignment and chroma geometry before using them to build a video buffer layout. A crafted file can cause an out-of-bounds heap read while the sample is copied, potentially crashing the application and causing denial of service.
