Microsoft Patch Tuesday: September 2025 Security Fixes

🔒 Microsoft today released Patch Tuesday updates addressing more than 80 vulnerabilities across Windows and related products, including 13 rated critical. There are no known zero‑day or actively exploited flaws in this bundle, but Microsoft patched several high‑risk issues such as CVE-2025-54918 (Windows NTLM), CVE-2025-55234 (SMB client), and CVE-2025-54916 (NTFS). Researchers warn many fixes are for privilege‑escalation bugs — some remotely exploitable — and note that Apple and Google recently patched zero‑days in their platforms as well.

August Windows updates trigger UAC prompts, block installs

⚠️ Microsoft says the August 2025 security updates are causing unexpected User Account Control (UAC) credential prompts and preventing application installations and MSI repair operations for non‑admin users across supported Windows client and server releases. The behavior stems from a patch addressing CVE-2025-50173, a Windows Installer privilege escalation vulnerability that now enforces elevated UAC prompts during MSI repair and related operations. Affected scenarios include MSI repair commands, ConfigMgr deployments relying on per‑user advertising, Secure Desktop enablement, and launching certain Autodesk applications. Microsoft plans a fix allowing admins to exempt specific apps and recommends running affected apps as administrator or applying a Known Issue Rollback via support as a temporary mitigation.
