CVE-2025-47982
7.8Microsoft · Windows
Improper input validation in the Windows Storage VSP Driver allows a locally authenticated attacker to gain elevated privileges on the target system.
Executive summary
A vulnerability in the Windows Storage VSP Driver allows an authenticated attacker to perform a local privilege escalation, posing a significant risk to system integrity.
Vulnerability
This vulnerability involves improper input validation and an untrusted pointer dereference within the Windows Storage VSP Driver. An attacker must already have local access and low-level privileges on the host system to trigger this flaw.
Business impact
Successful exploitation of this vulnerability allows a standard user to escalate their privileges to a higher level, potentially granting them administrative control over the affected system. Given the CVSS score of 7.8, this represents a high-severity risk that could lead to complete system compromise, unauthorized data access, and the bypass of security controls.
Remediation
Immediate Action: Apply the relevant security updates provided by Microsoft in the official update guide to patch the vulnerable driver.
Proactive Monitoring: Review system logs for unusual process execution patterns or attempts to access administrative resources by non-privileged user accounts.
Compensating Controls: Ensure that the principle of least privilege is strictly enforced across the environment to limit the impact of potential local privilege escalation attempts.
Exploitation status
Public Exploit Available: No
Analyst recommendation
Organizations should prioritize the deployment of the July 2025 security updates across all affected Windows versions. While the vector requires local access, the ability to achieve elevated privileges makes this a critical maintenance task for maintaining the security posture of enterprise endpoints and servers.
