Exposure of Sensitive Information to an Unauthorized Actor in firmware for some Intel(R) PROSet/Wireless Wi-Fi in multiple operating systems and some Killer(TM) Wi-Fi in Windows 10 and 11 may allow an authenticated user to potentially enable information disclosure via local access.

Security readout for executives and security teams

Plain-English summary

This flaw can let a logged-in local user expose sensitive information from firmware used by some Intel PROSet/Wireless Wi-Fi and Killer Wi-Fi products. It is not described as remotely exploitable and is not in CISA KEV. Business urgency is moderate: prioritize managed endpoints where local user access is common or where exposed Wi-Fi-related data could support further compromise.

Executive priority

Treat this as a moderate endpoint confidentiality risk. It is not a remote service exposure, but local authenticated disclosure on corporate laptops can still matter where sensitive data or elevated user access exists.

Technical view

CVE-2021-0170 is CWE-200 sensitive information exposure in firmware for some Intel PROSet/Wireless Wi-Fi across multiple operating systems and some Killer Wi-Fi on Windows 10 and 11. CVSS 3.1 is 5.5: local attack vector, low complexity, low privileges, no user interaction, unchanged scope, high confidentiality impact, no integrity or availability impact.

Likely exposure

Exposure likely centers on endpoints using affected Intel PROSet/Wireless Wi-Fi firmware or Killer Wi-Fi on Windows 10 and 11. The source bundle does not provide exact affected versions, so inventory must be matched against Intel advisory guidance.

Exploitation context

The provided sources describe exploitation by an authenticated user with local access. There is no supplied evidence of active exploitation, public weaponization, or inclusion in CISA KEV.

Researcher notes

The bundle lacks exact vulnerable versions and fixed versions. Validation should avoid assumptions and rely on Intel INTEL-SA-00539 plus OEM package metadata for device-specific mapping.

Mitigation direction

  • Review Intel advisory INTEL-SA-00539 for affected products and remediation guidance.
  • Update Wi-Fi firmware or drivers through Intel or OEM-approved channels where applicable.
  • Prioritize shared workstations, developer systems, and high-sensitivity endpoints.
  • Limit unnecessary local user access on systems with affected wireless hardware.

Validation and detection

  • Inventory endpoints with Intel PROSet/Wireless Wi-Fi or Killer Wi-Fi hardware and software.
  • Compare installed firmware and driver versions with Intel advisory guidance.
  • Confirm Windows 10 and 11 Killer Wi-Fi systems are included in assessment scope.
  • Document systems without clear version mapping for vendor or OEM follow-up.
