Networkmanager: networkmanager: 802-1x ca-path and phase2-ca-path bypass private_user restriction, allowing wpa-enterprise server validation bypass (incomplete fix for cve-2025-9615)

| Description | 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. |

Workarounds
CNA: Upstream fix is public: NetworkManager rejects 802-1x.ca-path and 802-1x.phase2-ca-path on private connections (those with connection.permissions) and requires ca-cert or system-ca-certs instead. Fixed upstream in commit a8e87381 (MR 2513), shipped in NetworkManager 1.58.1 and later 1.60 development snapshots. Until the fixed package is installed, use system-wide 802.1X profiles rather than per-user private ones, or set 802-1x.system-ca-certs=yes so the compiled system CA path overrides any user-supplied ca-path.
