Description
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to an error, related to port binding. 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.
Remediation
Install updates from vendor's website.
