USN-8806-1: NetworkManager vulnerability

Severity not listed 0 CVEs Published Sep 23, 2026 at 1:24 PM UTC

Summary

It was discovered that NetworkManager did not properly restrict the ca-path and phase2-ca-path certificate authority settings for private (single-user) 802.1X network connections. An attacker could use this issue to point their own private 802.1X connection profile at a directory under their control, causing NetworkManager to trust an attacker-chosen certificate authority and potentially exposing network credentials via a rogue authentication server.
