Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Stack-based buffer overflow in A5AGU.SYS 1.0.1.41 for the D-Link DWL-G132 wireless adapter allows remote attackers to execute arbitrary code via a 802.11 beacon request with a long Rates information element (IE).

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

Stack-based buffer overflow in the A5AGU.SYS wireless driver (v1.0.1.41) for the D-Link DWL-G132 adapter allows remote attackers to execute arbitrary code by sending a specially crafted 802.11 beacon frame containing an overly long Rates information element.

MitigationSince this is a driver-level vulnerability in likely end-of-life hardware, primary mitigation is to replace the affected DWL-G132 adapter with a currently supported device and ensure any replacement uses up-to-date wireless drivers from the vendor.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify D-Link DWL-G132 hardware
    Open Device Manager (devmgmt.msc) and look under Network adapters for D-Link DWL-G132, or run 'get-pnpdevice -class net' in PowerShell to list installed network adapters
    Affected if The DWL-G132 adapter appears in the system hardware list
  2. Locate A5AGU.SYS driver file
    Search for the file A5AGU.SYS in the Windows\System32\drivers directory or use 'driverquery /v | findstr A5AGU' to list driver information
    Affected if The A5AGU.SYS driver file exists on the system
  3. Verify driver version
    Right-click the A5AGU.SYS file, select Properties, then Details to view File Version, or run 'driverquery /v /fo csv | findstr A5AGU'
    Affected if The driver version is 1.0.1.41 (or any version of this driver, since all versions are affected)
  4. Confirm driver is loaded
    Open Services (services.msc) and check for wireless driver services, or run 'sc query type= driver' to list loaded kernel drivers and search for A5AGU
    Affected if The A5AGU driver is currently loaded and active in memory

A user is affected if the D-Link DWL-G132 adapter with the A5AGU.SYS driver is installed on the system, regardless of driver version since all versions are vulnerable.

Mitigation

Since this is a driver-level vulnerability in likely end-of-life hardware, primary mitigation is to replace the affected DWL-G132 adapter with a currently supported device and ensure any replacement uses up-to-date wireless drivers from the vendor.

Recommended fix Moderate confidence
  1. This vulnerability is in a legacy hardware driver (A5AGU.SYS) for the D-Link DWL-G132 wireless adapter, which is an end-of-life product from 2006.
  2. No vendor patch or firmware update is available for this device.
  3. If this hardware is still in use, consider replacing the DWL-G132 adapter with a current, supported wireless adapter.
  4. If replacement is not immediately possible, isolate systems using this adapter on a restricted network segment to limit exposure to beacon frame attacks.
  5. Monitor the vendor (D-Link) and security sources periodically for any future updates, though none are expected for this legacy device.
Caveat The D-Link DWL-G132 is end-of-life hardware with no driver updates available; replacement is the only viable remediation.
