Linux Distros Unpatched Vulnerability : CVE-2026-116309

high Nessus Plugin ID 380018

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.

 - Type confusion in PostgreSQL plperl may allow an object creator to execute arbitrary code, via blessing a non-hash reference into PostgreSQL::InServer::ARRAY. We have not confirmed or ruled out a way to control the pointer sufficiently to achieve security impact, but we are proceeding as though that is possible.
 Versions before PostgreSQL 18.7, 17.12, 16.16, 15.20, and 14.25 are affected. (CVE-2026-116309)

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

Solution

There is no known solution at this time.
