Linux Distros Unpatched Vulnerability : CVE-2026-19685

high Nessus Plugin ID 338782

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.

- NetworkManager did not apply the private_user restriction to the 802-1x.ca-path and phase2-ca-path directory-valued connection properties. This incomplete fix for CVE-2025-9615 allows an unprivileged local user to point a private WPA-Enterprise (802.1X) connection profile's CA path at an attacker-controlled directory, bypassing server certificate validation and enabling credential theft via a rogue access point.
(CVE-2026-19685)

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

Solution

There is no known solution at this time.
