CVE ID :CVE-2026-121601
Published : Nov. 9, 2026, 1:17 p.m. | 42 minutes ago
Description :A flaw was found in GStreamer's MXF demuxer plugin (gst-plugins-bad). When processing a specially crafted MXF media file, the demuxer indexes its internal delta-entry and slice-offset tables using values from the file without validating that they are within the bounds of the allocated arrays. A local attacker who tricks a user into opening a malicious MXF file can cause the application to crash (denial of service) and may be able to read limited amounts of heap memory adjacent to the affected arrays.
Severity: 6.1 | MEDIUM
