Actively exploited zero-day among dozens of patched Microsoft vulnerabilities

Updates have been issued by Microsoft to address 63 security issues impacting its products and systems, including an actively exploited high-severity zero-day in Windows Kernel, as part of this month's Patch Tuesday, reports CyberScoop .

Attacks involving the flaw, tracked as CVE-2025-62215, could enable threat actors with a race condition to achieve system privileges, according to Microsoft.

"Bugs like these are often paired with a code execution bug by malware to completely take over a system," said Trend Micro Zero Day Initiative Head of Threat Awareness Dustin Childs.

Vulnerabilities in the kernel-mode driver were also noted by Immersive's Ben McCarthy to be serious due to the component's importance in Windows operations.

Microsoft has also fixed a critical Graphics Component flaw, tracked as CVE-2025-60724, as well as five other bugs that have increased odds of being abused, three of which are high-severity issues impacting Windows Ancillary Function Driver for WinSock.
