Recommended fix Moderate confidence

Open5GS 2.7.7 or later (containing commit 98f76e98df35cd6a35e868aa62715db7f8141ac1)

  1. 1. Identify your current Open5GS version by checking the installed package or running 'open5gs --version'
  2. 2. Stop all Open5GS services to prevent during upgrade: 'sudo systemctl stop open5gs-*'
  3. 3. Upgrade Open5GS to version 2.7.7 or later which contains the security fix
  4. 4. Verify the upgrade was successful by checking the new version
  5. 5. Review and restart Open5GS services: 'sudo systemctl start open5gs-*'
  6. 6. Verify services are running properly: 'sudo systemctl status open5gs-*'
Caveat Standard minor version upgrade - review release notes for any configuration changes to GTPv2 handling
