Improper Validation of Specified Index, Position, or Offset in Input in software 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 unauthenticated user to potentially enable denial of service via adjacent access.

Security readout for executives and security teams

Plain-English summary

This CVE can let someone nearby disrupt affected Intel PROSet/Wireless Wi-Fi or Killer Wi-Fi software. The reported impact is denial of service, not data theft or system takeover, but it could interrupt connectivity on exposed laptops or endpoints.

Executive priority

Treat as a targeted availability risk, not a broad remote-compromise emergency. Prioritize mobile and user-facing endpoints that depend on Wi-Fi, especially in shared environments, and complete vendor-driven updates during normal security maintenance windows.

Technical view

CVE-2021-0183 is CWE-20 improper input validation involving an index, position, or offset in affected Wi-Fi software. CVSS 3.1 is 6.5 with adjacent attack vector, low complexity, no privileges, no user interaction, and high availability impact only.

Likely exposure

Exposure is limited to systems running affected Intel PROSet/Wireless Wi-Fi software across multiple operating systems or some Killer Wi-Fi software on Windows 10 and 11. Exact affected versions require Intel advisory review.

Exploitation context

The source bundle does not show CISA KEV listing or cited active exploitation. The CVSS vector requires adjacent access, so the realistic threat is a nearby unauthenticated actor causing wireless availability disruption.

Researcher notes

The bundle identifies the weakness class, CVSS vector, broad product families, and Intel advisory reference, but not exact affected or fixed versions. Avoid asserting exploitation or patch details without consulting INTEL-SA-00539 and applicable OEM driver advisories.

Mitigation direction

  • Review Intel advisory INTEL-SA-00539 for affected versions and vendor guidance.
  • Update affected Intel PROSet/Wireless Wi-Fi and Killer Wi-Fi software through approved vendor or OEM channels.
  • Prioritize endpoints that use Wi-Fi in public, shared, or physically accessible locations.
  • Where updates are unavailable, check Intel or OEM guidance for supported compensating controls.

Validation and detection

  • Inventory endpoints with Intel PROSet/Wireless Wi-Fi or Killer Wi-Fi software installed.
  • Compare installed Wi-Fi software and driver versions against Intel advisory INTEL-SA-00539.
  • Confirm whether Windows 10 or 11 systems include affected Killer Wi-Fi software.
  • Track remediation evidence through endpoint management or vulnerability management records.
