Linux Distros Unpatched Vulnerability : CVE-2026-125703

medium Nessus Plugin ID 378183

Synopsis

The Linux/Unix host has one or more packages installed with a vulnerability that the vendor indicates will not be patched.

Description

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

 - A flaw was found in the GStreamer gst-plugins-bad MXF plugin. Insufficient bounds checks when parsing crafted VANC data can cause an out-of-bounds read in the demuxer, while an incorrect buffer size calculation when muxing multiple ancillary packets can cause an out-of-bounds write. Processing affected content may crash the application, resulting in a denial of service. (CVE-2026-125703)

Note that Nessus relies on the presence of the package as reported by the vendor.

Solution

There is no known solution at this time.
