CVE-2025-62215: 
vulnerability analysis and mitigation

CVE-2025-62215 is a race condition vulnerability discovered in the Windows Kernel that was disclosed on November 11, 2025. The vulnerability affects multiple versions of Windows systems including Windows 10, Windows 11, and Windows Server editions. This security flaw has been confirmed to be actively exploited in the wild and was discovered by the Microsoft Threat Intelligence Center (MSTIC) and Microsoft Security Response Center (MSRC) (Tenable Blog, CrowdStrike Blog).

The vulnerability is classified as an elevation of privilege (EoP) flaw with a CVSSv3 score of 7.0 (High). It involves concurrent execution using shared resource with improper synchronization (CWE-362) in the Windows Kernel. The vulnerability requires local access with high attack complexity, low privileges, and no user interaction to exploit. When successfully exploited, attackers can gain SYSTEM-level privileges by winning a race condition (NVD, CrowdStrike Blog).

If successfully exploited, this vulnerability allows an authenticated attacker with low-level privileges to elevate their access to SYSTEM-level privileges, potentially enabling complete compromise of the system's confidentiality, integrity, and availability. This marks the 11th elevation of privilege vulnerability patched in the Windows kernel in 2025 (CrowdStrike Blog).

Microsoft has released security updates to address this vulnerability as part of the November 2025 Patch Tuesday. Organizations are advised to apply the security updates immediately. CISA has set a remediation date of December 3, 2025, for federal agencies to apply patches or implement mitigations (CISA KEV, Microsoft Advisory).
