AI-suggested
Red Hat advises setting the environment variable GST_PLUGIN_FEATURE_RANK=mpegpsdemux:NONE in affected processes to prevent automatic selection of the vulnerable MPEG Program Stream demuxer plugin. Applications explicitly using the affected plugins should avoid processing untrusted MPEG Program Stream or DVD input until a fixed package is available. These mitigations disable the vulnerable playback paths but are not complete fixes. Fixed versions are available starting with RHEL 10.4 and Fedora 44. Users should apply updates when they become available.
Description
CVE-2026-125706 is a moderate severity vulnerability in GStreamer's gst-plugins-bad MPEG Program Stream demuxer and resindvd DVD-playback plugin used in Red Hat Enterprise Linux 10. The flaw involves insufficient bounds checking in PES header parsing, which can lead to an out-of-bounds read when processing specially crafted MPEG Program Stream files. This may cause the application to crash, resulting in a denial of service. The vulnerability requires a user or media-processing pipeline to open the crafted file. Some affected Red Hat versions have fixes deferred under the Moderate policy, while newer versions like RHEL 10.4 are not affected. Mitigations include disabling the vulnerable plugin selection or avoiding untrusted input until a fix is available.
