CVE-2026-19685: 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)

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.

Security readout for executives and security teams

Plain-English summary

A local user on an affected RHEL 10 system can configure an enterprise Wi-Fi profile to trust certificates from an attacker-controlled directory. Combined with a rogue access point, this could defeat server identity checks and expose enterprise Wi-Fi credentials. The supplied record identifies other listed Red Hat platforms as unaffected.

Executive priority

Treat this as an urgent endpoint credential-protection issue for RHEL 10 environments using enterprise Wi-Fi. Rapidly identify affected systems and follow Red Hat remediation guidance. Scope carefully because the supplied data names several Red Hat platforms as unaffected and omits exact affected version ranges.

Technical view

NetworkManager omitted private_user authorization restrictions for the directory-valued 802-1x.ca-path and phase2-ca-path properties. An unprivileged local user can therefore redirect CA lookup for a private 802.1X profile, bypassing expected certificate validation. This is an incomplete fix for CVE-2025-9615 and is classified as CWE-863.

Likely exposure

Prioritize RHEL 10 endpoints running NetworkManager, particularly systems where unprivileged or untrusted local users can create private WPA-Enterprise profiles. The bundle provides no affected package-version boundaries. RHEL 6 through 9, Red Hat Hardened Images, and OpenShift Container Platform 4 are listed as unaffected.

Exploitation context

Exploitation requires influence over a local user's private 802.1X profile and an attacker-controlled rogue access point capable of impersonating the enterprise network. Credential theft is the stated consequence. The supplied record is not in KEV and provides no evidence of active exploitation.

Researcher notes

The security boundary failure concerns authorization of directory-valued CA properties, not a general cryptographic break. Assessment should distinguish private user profiles from administrator-managed profiles and confirm both outer and phase-two CA paths. Public commits and merge request indicate corrective development, but the bundle does not identify fixed downstream package versions.

Mitigation direction

  • Check Red Hat guidance for affected NetworkManager package versions and corrected releases.
  • Apply the vendor-provided NetworkManager update when available through supported repositories.
  • Prioritize managed RHEL 10 endpoints using WPA-Enterprise networks.
  • Until updated, investigate unauthorized private 802.1X profiles or attacker-controlled CA directories.

Validation and detection

  • Inventory RHEL 10 systems and record their installed NetworkManager package versions.
  • Compare installed packages with Red Hat's current affected and fixed version guidance.
  • Review private 802.1X profiles for ca-path and phase2-ca-path directory settings.
  • Confirm listed unaffected Red Hat platforms are not incorrectly included in remediation scope.
  • After updating, verify the corrected NetworkManager package is installed and active.
