OpenStack Nova instance migration process does not stop when instance is deleted

  • Disclosed: 14.05.2022
  • Updated: 11.10.2026 15:17

OpenStack Compute (nova) 2015.1 through 2015.1.1, 2014.2.3, and earlier does not stop the migration process when the instance is deleted, which allows remote authenticated users to cause a denial of service (disk, network, and other resource consumption) by resizing and then deleting an instance.
