AI-suggested
A fix is available by updating gst-plugins-good to version 1.28.3 or later. If updating is not possible, avoid processing untrusted MOV/MP4 files with qtdemux. Deployments that do not require MOV/MP4 support can disable the isomp4 plugin to mitigate the risk. Red Hat's advisory provides these recommendations and no further immediate action is required if the fix is applied.
Description
CVE-2026-125041 is a vulnerability in GStreamer's gst-plugins-good MOV/MP4 demuxer used in Red Hat Enterprise Linux 10. The flaw involves improper validation of declared row alignment and chroma geometry in uncompressed video tracks, leading to an out-of-bounds heap read. This can cause the application processing the crafted file to crash, resulting in a denial of service condition. The issue is addressed in gst-plugins-good version 1.28.3 and later.
