CVE-2025-20622
📋 TL;DR
This vulnerability in Intel NPU Drivers for Windows allows unprivileged local users to potentially access sensitive information left in memory after resource release. It affects systems running vulnerable Intel NPU drivers before version 32.0.100.4023 on Windows. Attackers need local access and authenticated user privileges to exploit this information disclosure flaw.
💻 Affected Systems
- Intel(R) NPU Drivers for Windows
⚠️ Manual Verification Required
This CVE does not have specific version information in our database, so automatic vulnerability detection cannot determine if your system is affected.

⚠️ Risk & Real-World Impact
Worst Case
Sensitive data from previously used NPU resources could be exposed to local attackers, potentially revealing application data, cryptographic keys, or other memory contents.
Likely Case
Limited information disclosure of residual data from NPU operations, potentially exposing fragments of application data but not full system compromise.
If Mitigated
No data exposure occurs due to proper memory clearing or patched drivers.
🎯 Exploit Status
Attack requires local access, authenticated user privileges, and low complexity attack. No special internal knowledge or user interaction needed.
🛠️ Fix & Mitigation

🔧 Temporary Workarounds
Restrict Local Access
windowsLimit physical and remote local access to systems with vulnerable drivers
User Privilege Reduction
windowsEnsure users only have necessary privileges to reduce attack surface
🧯 If You Can't Patch
- Implement strict access controls to limit who can log into affected systems
- Monitor for unusual local access patterns or privilege escalation attempts
