      "value": "An issue was discovered in OpenStack Nova before 23.2.2, 24.x before 24.1.2, and 25.x before 25.0.2. By creating a neutron port with the direct vnic_type, creating an instance bound to that port, and then changing the vnic_type of the bound port to macvtap, an authenticated user may cause the compute service to fail to restart, resulting in a possible denial of service. Only Nova deployments configured with SR-IOV are affected."

      "value": "Se ha detectado un problema en OpenStack Nova versiones anteriores a 23.2.2, 24.x anteriores a 24.1.2 y 25.x anteriores a 25.0.2. Al crear un puerto de neutrones con el vnic_type directo, crear una instancia vinculada a ese puerto y luego cambiar el vnic_type del puerto vinculado a macvtap, un usuario autenticado puede causar que el servicio de computaci\u00f3n no sea reiniciado, resultando en una posible denegaci\u00f3n de servicio. S\u00f3lo est\u00e1n afectadas las implantaciones de Nova configuradas con SR-IOV"
