Up next on the patch priority list this month are patches for Microsoft Edge, Excel, Outlook, and PowerPoint. These patches resolve 11 vulnerabilities that exist due to issues such as memory corruption, information disclosure, security feature bypass, and remote code execution vulnerabilities.

Next are patches that affect components of the Windows operating systems. They resolve over 20 vulnerabilities, including elevation of privilege, information disclosure, remote code execution, and memory corruption vulnerabilities. These vulnerabilities affect core Windows, GDI, Kerberos, Error Reporting, Hyper-V, DirectX, Backup Engine, Cloud Files Mini Filter Driver, and others.
