CVE-2025-62215 is an actively exploited Windows Kernel privilege-escalation flaw that can turn a post-compromise foothold into admin-level rights.

The exploitation status makes the issue urgent for Windows defenders because compromised systems can be elevated to deeper control.

Microsoft November security update highlights active Windows Kernel flaw
Initial DisclosureMicrosoft's November security update covers 63 unique CVEs and includes one actively exploited flaw, one critical vulnerability, and five additional bugs Microsoft rates as more likely to be targeted. CVE-2025-62215 affects the Windows Kernel and is already being exploited for post-compromise privilege escalation to admin-level rights, while CVE-2025-60724 is a critical CVSS 9.8 RCE in the GDI+ Windows graphics component that can be triggered on Web services by uploading documents containing a malicious metafile. The update also includes CVE-2025-60704, a Windows Kerberos elevation-of-privilege flaw that Silverfort says can affect organizations using Active Directory with Kerberos delegation enabled, alongside other more exploitable privilege-escalation issues in Windows Subsystem for Linux GUI and the Windows Ancillary Function Driver of WinSock.
