Microsoft Patch Tuesday, November 2025 Security Update Review | Qualys
Summary: Microsoft's November 2025 Patch Tuesday addresses 68 vulnerabilities, including five critical and 59 important-severity flaws, plus five in Microsoft Edge (Chromium-based). The release includes a zero-day vulnerability that was being exploited in the wild, which CISA added to its Known Exploited Vulnerabilities Catalog with a patch deadline of December 3, 2025.
Key Takeaway: One of this month's 68 flaws is already being exploited in the wild, and CISA's December 3 deadline leaves a narrow window to patch it before it becomes an audit finding or an incident.
