How to fix CVE-2026-105031
Upgrade to a fixed release named by Red Hat:
- 0.41.1
Vendor guidance
- Configure the environment of affected processes to override the default OpenSSL certificate store path to `/dev/null`. This ensures that only explicitly configured CA certificates are trusted. For standalone or shell-executed processes: ``` export SSL_CERT_FILE=/dev/null ``` For systemd-managed services, create or edit a drop-in override (e.g., using `systemctl edit <service_name>`): ``` [Service] Environment="SSL_CERT_FILE=/dev/null" ``` Apply the changes by reloading systemd and restarting the service: ``` systemctl daemon-reload systemctl restart <service_name> ``` Caveats: Setting `SSL_CERT_FILE=/dev/null` disables loading of standard operating system CA certificates. Any connection depending on system-wide root CAs will fail certificate verification unless explicitly added to the application's trust store. Warning: Restarting services will terminate active network connections and interrupt in-flight message delivery.
