When an application processes a crafted MXF file, an off-by-one bounds check can allow a one-byte write past the logical end of a temporal offset array. This may corrupt memory and cause the application to crash. The extent of the impact has not been demonstrated by a runtime test.","epss":{"date":"2026-11-12","percentile":0.04534,"score":0.00153},"exploits":[],"kev":null,"metrics":[{"score":7.1,"severity":"high","source":"CNA: redhat","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:H","version":"3.1"},{"score":6.1,"severity":"medium","source":"NVD: secalert@redhat.com","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:H","version":"3.1"}],"modifiedAt":1794505750707,"publishedAt":1794309796522,"references":[{"source":"CNA: redhat","tags":["vdb-entry","x_refsource_REDHAT"],"url":"https://access.redhat.com/security/cve/CVE-2026-125707"},{"source":"CNA: redhat","tags":["issue-tracking","x_refsource_REDHAT"],"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2569127"},{"source":"CNA: redhat","tags":[],"url":"https://gstreamer.freedesktop.org/security/sa-2026-0027.html"},{"source":"secalert@redhat.com","tags":[],"url":"https://access.redhat.com/security/cve/CVE-2026-125707"},{"source":"secalert@redhat.com","tags":[],"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2569127"},{"source":"secalert@redhat.com","tags":[],"url":"https://gstreamer.freedesktop.org/security/sa-2026-0027.html"}],"remediation":[{"kind":"workaround","source":"CNA: redhat","text":"Where MXF processing is not required, set GST_PLUGIN_FEATURE_RANK=mxfdemux:NONE before launching a GStreamer application to prevent automatic selection of mxfdemux for untrusted files.
