Linux Distros Unpatched Vulnerability : CVE-2026-88914

high Nessus Plugin ID 344704

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 GStreamer's gst-plugins-good isomp4 plugin. When processing a specially crafted MP4 or MOV file containing CEA-608 closed-caption data, an integer overflow in 32-bit unsigned arithmetic can bypass a bounds check in the caption parser. This leads to an out-of-bounds heap read of up to 244 bytes, which is then included in the downstream caption output. An attacker could exploit this by tricking a user into opening a malicious media file, potentially resulting in disclosure of adjacent heap memory or application crash. (CVE-2026-88914)

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

Solution

There is no known solution at this time.
