How to fix?

There is no fixed version for RHEL:8 openstack-designate-api.

NVD Description

Note: Versions mentioned in the description apply only to the upstream openstack-designate-api package and not the openstack-designate-api package as distributed by RHEL. See How to fix? for RHEL:8 relevant fixed versions and status.

In OpenStack Designate before 22.0.2, the mDNS handler performs pool-blind lookups when resolving record queries and NOTIFY requests. When two zones with the same name exist across different pools, the lookup fails with a deterministic error, causing the handler to return REFUSED for all DNS queries through that path. The _handle_notify path is exploitable via a single unauthenticated UDP packet. This is independently reachable through the cross-tenant zone overlap described in a different recent CVE, and also affects legitimate same-tenant cross-pool configurations. BIND9 views do not mitigate this issue as mDNS is a shared service upstream of any view configuration.
