What is CVE-2025-62215?

CVE-2025-62215 is a vulnerability identified within the Windows Kernel, specifically a race condition that occurs due to improper synchronization of concurrent executions using shared resources. This flaw allows authorized users to elevate their privileges locally, which can result in unauthorized access to system components that are otherwise restricted. As the Windows Kernel is a core element of the Windows operating system, the impact of such a vulnerability is extensive, potentially compromising the integrity of system security measures. If exploited, the vulnerability could allow attackers to execute code or commands at a higher privilege level than intended, thereby gaining control over critical system functionalities.

Potential impact of CVE-2025-62215

Unauthorized Privilege Escalation: The most immediate risk is the ability for authorized users to escalate their privileges, potentially allowing them to manipulate system settings or access sensitive data that should remain protected. This could lead to significant breaches of confidentiality and data integrity.
System Integrity Risks: With elevated privileges, attackers could alter or corrupt essential system files and processes, undermining the overall integrity of the operating system. This could lead to further exploitation opportunities or system instability.
Increased Attack Surface: The existence of this vulnerability raises the attack surface for organizations. Even if not actively exploited in the wild, the potential for misuse by internal or external actors necessitates immediate attention and remediation efforts to ensure organizational security remains intact.

CISA has reported CVE-2025-62215

CISA provides regional cyber and physical services to support security and resilience across the United States.
