Assurance Security Dashboard May 2026
Microsoft’s May 2026 Patch Tuesday ships 137 fixes spanning 67 Windows entries, 27 in Office, 11 in Developer Tools, 6 across Browser, and a single SQL Server item. Exchange is quiet this month. No zero-days were disclosed or actively exploited at release.
The headline severity sits in Developer Tools with a lone CVSS 10.0 issue, alongside nine critical Office CVEs and six critical Windows fixes. Windows networking dominates by volume: TCP/IP carries nine separate CVEs this cycle, the Ancillary Function Driver for WinSock four, and CLFS, Win32k, DWM Core Library, and the Cloud Files Mini Filter Driver each pick up a handful.
