Introduction

A critical integer overflow vulnerability (CVE-2025-48816) in the Windows HID Class Driver has emerged, posing a significant threat to systems running Windows 10, Windows 11, and Windows Server editions. This flaw enables local attackers with standard user privileges to escalate their access to SYSTEM-level, potentially compromising entire systems.

Technical Information

The vulnerability originates from an integer overflow or wraparound (CWE-190) within the HID Class Driver (hidclass.sys). This kernel-mode driver processes input from human interface devices (HID), such as keyboards and mice. Maliciously crafted input data can trigger incorrect memory allocation, resulting in heap-based buffer corruption. Successful exploitation requires local access and execution of specially crafted code, allowing attackers to escalate from standard user privileges to SYSTEM-level access.

Attack Vectors

  • Local Access: Exploitation requires local system access, either physically or via remote desktop sessions.
  • Malicious Input: Attackers must execute specifically crafted code to exploit the integer overflow vulnerability.

Patch Information

Microsoft has addressed this vulnerability in their July 2023 security updates. Key updates include:

  • Windows 11 Version 22H2: Update KB5028185 (OS Build 22621.1992)
  • Windows 11 Version 21H2: Update KB5028182 (OS Build 22000.2176)
  • Windows Server 2008 SP2: Update KB5028222 (Monthly Rollup)
  • Windows Server 2012 R2: Update KB5028228 (Monthly Rollup)

These updates are critical for maintaining system integrity and protecting against potential exploits.

Affected Systems and Versions

  • Windows 10 (all versions prior to July 2023 updates)
  • Windows 11 (all versions prior to July 2023 updates)
  • Windows Server 2008 SP2
  • Windows Server 2012 R2

Vendor Security History

Microsoft has a consistent track record of addressing HID-related vulnerabilities promptly. Previous similar vulnerabilities, such as CVE-2019-19307, were also swiftly patched, demonstrating Microsoft's proactive approach to security management.
