Microsoft Patches 137 Flaws, Highlighting Word Preview Pane and Netlogon RCE Risks
Microsoft released its May Patch Tuesday updates fixing 137 vulnerabilities across Windows, Office, Azure, Dynamics 365, SharePoint, Copilot, and other products, with no actively exploited zero-days or publicly disclosed flaws reported at release. The update included multiple high-severity remote code execution bugs, notably Microsoft Word flaws CVE-2026-40361 and CVE-2026-40364, which can be triggered through the Preview Pane by sending a malicious document, as well as CVE-2026-42898 in Microsoft Dynamics 365 On-Premises, CVE-2026-42823 in Azure Logic Apps, and CVE-2026-33109 in Azure Managed Instance for Apache Cassandra. Researchers also flagged CVE-2026-41089 in Windows Netlogon and CVE-2026-41096 in Windows DNS Client as especially urgent because they expose broadly deployed enterprise infrastructure to remote compromise.
