Ubuntu Security Notices (USNs) publish vulnerability advisories for Ubuntu packages, each referencing one or more CVEs. This processor keeps unresolved CVEs in a persistent JSON file, retries them until Vulmatch returns a vulnerability, and attaches USN note context linking back to the originating notice.
