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.

The remote Ubuntu 26.04 LTS host has packages installed that are affected by a vulnerability as referenced in the USN-8806-1 advisory.

    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.
