Microsoft has released critical security updates for Windows 10 and 11, addressing multiple zero-day vulnerabilities and critical security issues. The Patch Tuesday update includes fixes for both Windows desktop and Server versions.

Key Vulnerabilities Fixed:

• Six actively exploited zero-day vulnerabilities
• Six additional critical security issues

• CVE-2025-24991: Virtual hard disk data access vulnerability
• CVE-2025-24984: Log file manipulation vulnerability
• CVE-2025-26633: Microsoft Management Console Security bypass (affecting 600+ organizations)

Impact and Urgency:

The Zero Day Initiative describes the number of actively exploited bugs as "extraordinary" and urges system administrators to implement these patches immediately. The vulnerabilities could allow attackers to:

• Execute remote code
• Access sensitive data
• Manipulate system logs
• Bypass security features

Additional Updates:

Adobe has also released security patches for multiple products:

• Acrobat Reader
• Substance 3D Suite (Sampler, Painter, Modeler, Designer)

While Adobe's vulnerabilities aren't currently being exploited, users should update their software promptly for maximum security.

Users are strongly advised to install these updates immediately to protect their systems from potential attacks and unauthorized access.
