CVE-2025-62215 is a high-severity vulnerability that affects multiple versions of Microsoft Windows, including Windows 10 and Windows 11. This vulnerability allows an authorized attacker to elevate privileges locally through a race condition in the Windows Kernel. The CVSS score for this vulnerability is 7, indicating significant risk for organizations if left unaddressed.
The exploitation status is critical as exploits are known to exist, and the vulnerability has been acknowledged in the Known Exploited Vulnerabilities (KEV) catalog. Organizations should prioritize applying the available patches to prevent potential security breaches.
Risk to organizations includes unauthorized access to sensitive information and control over affected systems. The urgency for defenders is critical, necessitating immediate action to patch the vulnerability.
Given that this vulnerability is actively exploited, organizations running any of the affected versions should take immediate steps to secure their systems.
Vulnerability Details
This vulnerability allows concurrent execution using shared resources with improper synchronization, leading to a race condition in the Windows Kernel. The affected products include several versions of Windows 10, Windows 11, and Windows Server. The vulnerability was published on November 11, 2025, and it has been classified with CWE IDs CWE-362 and CWE-415.
The CVSS vector for this vulnerability is CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H, indicating a local attack vector with high complexity and low privileges required for exploitation.
Technical Analysis
The root cause of CVE-2025-62215 stems from improper synchronization in the Windows Kernel, allowing concurrent execution with shared resources. The attack vector is local, meaning an attacker needs to have access to the system to exploit this issue. The attack complexity is rated as high, requiring specific conditions to be met for successful exploitation.
The privileges required for exploitation are low, as an attacker only needs to have limited access. No user interaction is necessary, which increases the risk of exploitation. If successfully exploited, this vulnerability can lead to high impacts on confidentiality, integrity, and availability.
Risk & Impact Analysis
Organizations that fail to address this vulnerability may face significant risks, including unauthorized access to sensitive data and critical system control. The potential blast radius includes all systems running the affected versions of Windows, making the need for immediate remediation crucial.
The urgency assessment, based on CVSS and KEV status, indicates that organizations should prioritize patching immediately to mitigate the risk of exploitation.
Exploitation Status
Signal | Status |
|---|---|
Known Exploit | Yes |
Public PoC | Yes |
Actively Exploited | Yes |
Ransomware Use | No |
Affected Versions
The affected versions include Windows 10 (1809, 21H2, 22H2), Windows 11 (23H2, 24H2, 25H2), and Windows Server (2019, 2022, 2022 23H2, 2025). Organizations running these versions should ensure they apply the necessary patches.
Mitigation & Remediation
