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
The Marvell driver for the Linksys WAP4400N Wi-Fi access point with firmware 1.2.14 on the Marvell 88W8361P-BEM1 chipset, when WEP mode is enabled, does not properly parse malformed 802.11 frames, which allows remote attackers to cause a denial of service (reboot or hang-up) via a malformed association request containing the WEP flag, as demonstrated by a request that is too short, a different vulnerability than CVE-2008-1144 and CVE-2008-1197.

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

The Marvell 88W8361P-BEM1 chipset driver in Linksys WAP4400N access points with firmware 1.2.14 contains a parsing vulnerability when WEP encryption is enabled. Remote attackers can send a malformed 802.11 association request frame that is too short, triggering a buffer handling error that causes the device to reboot or hang, resulting in denial of service.

MitigationDisable WEP encryption and migrate to WPA or WPA2 encryption if available on the device; if the device cannot support modern encryption protocols, replace the access point with a current model that receives vendor security updates.

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 the exact access point model
    Locate the device label or check the administrative web interface for the model number. Confirm it is a Linksys WAP4400N access point.
    Affected if The device is not a Linksys WAP4400N, then it is not affected by this specific CVE.
  2. Check the installed firmware version
    Access the device administrative interface or check the firmware file loaded on the device. Look for the firmware version displayed in the system status or management page.
    Affected if The firmware version is 1.2.14 - only this specific version is affected.
  3. Verify WEP encryption is enabled
    Navigate to the wireless security settings in the device administrative interface. Check whether WEP (Wired Equivalent Privacy) is selected as the encryption method.
    Affected if WEP encryption must be enabled for the vulnerability to be exploitable; the device is only affected when WEP is active.
  4. Confirm the device is reachable and responsive
    Attempt to ping the access point or access its web interface to verify it has not already crashed or become unavailable due to the vulnerability.
    Affected if If the device is unresponsive or has rebooted repeatedly, this may indicate the vulnerability has been triggered, but this check alone does not determine susceptibility.

The device is affected only if it is a Linksys WAP4400N running firmware version 1.2.14 with WEP encryption enabled; if any of these conditions is not met, the environment is not vulnerable to this CVE.

Mitigation

Disable WEP encryption and migrate to WPA or WPA2 encryption if available on the device; if the device cannot support modern encryption protocols, replace the access point with a current model that receives vendor security updates.
