Linux Distros Unpatched Vulnerability : CVE-2026-116316

high Nessus Plugin ID 380112

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 protection of alternate path in PostgreSQL security-restricted operations allows an object creator to execute arbitrary SQL as the operation's caller, via a domain, enum, or range type created in pg_temp. The victim session must later run a query containing an unqualified type name, e.g. SELECT '1'::bigint; autovacuum and other common security-restricted operation users do not do so, so they are unaffected. Versions before PostgreSQL 18.7, 17.12, 16.16, 15.20, and 14.25 are affected.
 (CVE-2026-116316)

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

Solution

There is no known solution at this time.
