Microsoft Patches Actively Exploited Windows Zero-Day in November Security Update

/

Microsoft’s latest November Patch Tuesday rollout includes fixes for multiple high-severity vulnerabilities — including one zero-day that attackers are actively exploiting to take control of Windows systems.

This month’s patches are critical for Windows 10, Windows 11, Windows Server, Microsoft Office, and several related services. Skipping this update could leave your system vulnerable to malware, data theft, or full administrative takeover.

🧩 What’s Been Fixed

Every second Tuesday of the month, Microsoft releases a new wave of security fixes — known as Patch Tuesday. November’s batch targets a range of serious vulnerabilities, most notably:

1. CVE-2025-62215 — Windows Kernel Elevation of Privilege (Zero-Day)

This zero-day vulnerability has already been exploited in the wild. It’s an Elevation of Privilege (EoP) flaw in the Windows Kernel that allows attackers to gain administrator-level permissions on a compromised system.

The bug stems from a race condition — a timing issue where multiple processes try to access the same resource simultaneously. By exploiting that brief moment of confusion, attackers can execute code with higher privileges, effectively taking full control of the device.

Attackers typically chain this flaw with other exploits to move from limited user access to full system admin rights.

2. CVE-2025-60724 — Microsoft Graphics Component (GDI+) Remote Code Execution

This critical Remote Code Execution (RCE) bug carries a CVSS score of 9.8 out of 10, meaning it’s extremely dangerous. It’s a heap-based buffer overflow vulnerability in the GDI+ graphics component used by Windows and Microsoft Office.

An attacker can trigger this flaw by convincing someone to open a malicious file or document — such as a booby-trapped image or metafile. More advanced attackers could exploit it remotely by uploading a crafted file to a vulnerable web service.

If successful, they can run arbitrary code on the target system, install malware, steal information, or use the compromised machine to spread further attacks.

🔐 Why It Matters

Zero-day exploits give attackers an advantage — they can strike before defenders even know a flaw exists. That’s why installing updates promptly is one of the simplest yet most effective ways to secure your system.

With attackers already exploiting CVE-2025-62215, it’s critical for all Windows users — home and enterprise alike — to patch as soon as possible.
