Senserva AI Opinion for KB5002664

KB5002664 fixes the same four-CVE subset as KB5002544 within December 2024's SharePoint release, at High, CVSS 8.2. Multiple four- and five-CVE variants shipping the same month is standard SharePoint servicing across build combinations, not a sign of differing severity.
