Linux Distros Unpatched Vulnerability : CVE-2026-2003

medium Nessus Plugin ID 298913

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.

 - Improper validation of type oidvector in PostgreSQL allows a database user to disclose a few bytes of server memory. We have not ruled out viability of attacks that arrange for presence of confidential information in disclosed bytes, but they seem unlikely. Versions before PostgreSQL 18.2, 17.8, 16.12, 15.16, and 14.21 are affected. (CVE-2026-2003)

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

Solution

There is no known solution at this time.
