Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
A flaw was found in Open Virtual Network where the service monitor MAC does not properly rate limit. This issue could allow an attacker to cause a denial of service, including on deployments with CoPP enabled and properly configured.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis
How this class of weakness works · CWE-400

A single request can consume unbounded CPU, memory, or connections, so a modest amount of malicious traffic exhausts the service. The result is denial of service for everyone else. Remediation is enforcing limits, quotas, and timeouts on what any one request can use.

Recommended fix High confidence

Open Virtual Network: 23.03.1 or later; OpenShift Container Platform: upgrade to 4.10 or later to get fixed OVN components

  1. Identify the current version of Open Virtual Network (OVN) in use by checking the OVN packages or containers
  2. For Open Virtual Network: upgrade to version 23.03.1 or later, which contains the fix for the rate limiting issue in service monitor MAC
  3. For Fast Datapath: upgrade to a version that includes the OVN 23.03.1 or later fix
  4. For OpenShift Container Platform 4.0: upgrade to a later OpenShift release (4.10 or later) that incorporates the fixed OVN version
  5. After upgrade, verify that the service monitor MAC rate limiting is functioning correctly by reviewing logs and monitoring for any MAC-related traffic anomalies
  6. For deployments with CoPP (Control Plane Protection), verify CoPP rules are still properly configured after the upgrade
Caveat Review OVN release notes between current version and 23.03.1+ for any behavioral changes or required configuration updates; ensure dependent workloads are compatible
