It’s that time again – Patch Tuesday is here. This November, Microsoft rolled out fixes for 63 security flaws, featuring one actively exploited zero-day and four Critical vulnerabilities.
Today also marks the release of the first Extended Security Update (ESU) for Windows 10. Organizations still using this unsupported operating system are strongly encouraged to upgrade to Windows 11 or participate in the ESU program to continue receiving security updates.
Once again, Elevation of Privilege (EoP) vulnerabilities top the list, closely followed by Remote Code Execution (RCE) flaws.
Summary Overview
| Category | Number of Flaws |
|---|---|
| Total Vulnerabilities | 63 |
| Zero-Days | 1 (actively exploited) |
| Critical | 4 |
| Elevation of Privilege | 29 |
| Remote Code Execution | 16 |
| Information Disclosure | 11 |
| Denial of Service | 3 |
| Security Feature Bypass | 2 |
| Spoofing | 2 |
Key takeaway: Local privilege escalations remain the most common vulnerability type, but several RCE and information disclosure issues elevate this month’s risk profile.
Vulnerability Highlights
CVE-2025-62215: Windows Kernel Elevation of Privilege (Zero-Day)
This zero-day vulnerability in the Windows Kernel allows authenticated local attackers to gain SYSTEM privileges by exploiting a race condition in a shared resource.
The issue has been given a CVSS rating of Important, and Microsoft confirms that the flaw was actively exploited in the wild before the patch was released. Affected systems include various Windows versions (Kernel component). Because the attacker must already have some local access, this is a post-compromise privilege escalation scenario.
CVE-2025-62199: Microsoft Office Remote Code Execution Vulnerability (Critical)
A use-after-free vulnerability in Microsoft Office that may allow an attacker to execute arbitrary code remotely when a user opens or previews a malicious file.
CVE-2025-30398: Nuance PowerScribe 360 Information Disclosure Vulnerability (Critical)
An information disclosure vulnerability in Nuance PowerScribe 360 that allows an unauthenticated attacker to access sensitive data via a network API endpoint missing proper authorization.
CVE-2025-62214: Visual Studio Remote Code Execution Vulnerability (Critical)
A command-injection flaw in Microsoft Visual Studio’s AI/agent capabilities that may permit code execution when an attacker crafts malicious prompt/input for the AI agent and triggers a build.
CVE-2025-60716: DirectX Graphics Kernel Elevation of Privilege (Critical)
This is a kernel e-privilege vulnerability in Windows DirectX graphics subsystem (use-after-free) that allows local, authenticated attackers to elevate to SYSTEM via a race condition.
