There were over 100 CVEs addressed (higher than normal) in this patch set. There were two 9.8 CVSS scores but both are GDI issues that are exploitable by user browsing. MSMQ, Office, and Hyper-V have significant fixes.
A publicly released Kerberos vulnerability (CVE-2025-53779) was patched. Exploit requires elevated privileges so there is some existing mitigation until patches are deployed.
Recommending normal patching and testing with expedited deployment for workstations, systems using Sharepoint, MSMQ and Hyper-V.
Testing and patching should be started for all systems. Please note that are several Office application patches so endpoints are in scope
All admins are reminded that browser updates, including updates to Edge Chrome and Firefox, should be deployed regularly. There are Edge patches in scope for this patch set.
