• New vulnerability grants full system privileges
• Urgent updates required to protect individual and enterprise devices

Microsoft has issued a security alert regarding a critical vulnerability in Windows 10 and 11, putting millions of devices worldwide at risk

The flaw allows attackers to gain full system privileges if successfully exploited, increasing the danger to both personal and organizational devices

Known as "CVE‑2025‑62215," the vulnerability enables privilege escalation even with limited initial access, making it an attractive target for ransomware operators and cyber spies

Microsoft highlighted that devices running supported versions or under extended security updates are particularly at risk, stressing the urgency of applying patches as soon as possible

The company emphasized that installing security updates—including emergency patches outside the regular schedule—is essential to prevent exploitation and avoid turning devices into easy targets

Privilege escalation in the system kernel is a critical step in many advanced attacks, as a compromised device can become a platform for spreading within networks, even when initial access is limited

Experts warn that delaying updates or ignoring precautionary measures may result in full device compromise or usage within broader cyberattacks

Security authorities recommend monitoring network activity, using strong passwords, enabling two-factor authentication, avoiding unknown links or attachments, and prioritizing devices that could serve as potential entry points in enterprise environments

Microsoft’s warnings serve as a wake-up call for Windows 10 and 11 users, as the threat is real; postponing updates or protective measures could come at a high cost to devices and data
