Linux Distros Unpatched Vulnerability : CVE-2026-125709

critical Nessus Plugin ID 378154

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 libstdc++. When a byte-by-byte write operation fails during file stream processing, the library may still append data into the internal memory buffer. An attacker capable of inducing repeated write failures in an affected service can trigger a buffer overflow, potentially resulting in a Denial of Service (DoS) or memory corruption. (CVE-2026-125709)

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

Solution

There is no known solution at this time.
