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
An issue was discovered in Marvell 88W8688 Wi-Fi firmware before version p52, as used on Tesla Model S/X vehicles manufactured before March 2018, via the Parrot Faurecia Automotive FC6050W module. A stack overflow could lead to denial of service or arbitrary code execution.

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 · moderate confidence

A stack buffer overflow vulnerability exists in Marvell 88W8688 Wi-Fi firmware versions prior to p52, as deployed in Tesla Model S/X vehicles through the Parrot Faurecia FC6050W module. The overflow can be exploited to cause denial of service or achieve arbitrary code execution on the affected Wi-Fi chip.

MitigationUpdate the Marvell 88W8688 Wi-Fi firmware to version p52 or later; Tesla vehicles require the manufacturer-provided security update for affected model years.

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 Wi-Fi hardware module
    Inspect the vehicle's infotainment system or network components to determine if the Parrot Faurecia FC6050W module is present. This may require accessing the hardware BOM, service documentation, or diagnostic tools for the affected Tesla Model S/X vehicles.
    Affected if The Parrot Faurecia FC6050W module is present in the vehicle
  2. Verify Marvell 88W8688 chip presence
    Confirm that the Marvell 88W8688 Wi-Fi chip is integrated within the FC6050W module. This may be verifiable through hardware inspection, module firmware identification, or vehicle diagnostic interfaces.
    Affected if The Marvell 88W8688 Wi-Fi chip is present in the system
  3. Retrieve the firmware version
    Use appropriate diagnostic or firmware extraction methods to read the current firmware version installed on the Marvell 88W8688 chip. This may require specialized automotive diagnostic tools or direct firmware dumping from the module.
    Affected if A firmware version can be retrieved from the chip
  4. Compare version against affected range
    Compare the retrieved firmware version against the affected range: versions prior to p52. Ensure the exact version string is identified (e.g., p51, p50, or earlier).
    Affected if The installed firmware version is less than p52 (for example, p51, p50, or any earlier version)

The environment is affected if the Parrot Faurecia FC6050W module with the Marvell 88W8688 chip is present and its firmware version is below p52.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Update the Marvell 88W8688 Wi-Fi firmware to version p52 or later; Tesla vehicles require the manufacturer-provided security update for affected model years.

Recommended fix High confidence

p52 (or later)

  1. Identify the Marvell 88W8688 Wi-Fi firmware version currently installed on the affected device or vehicle infotainment system
  2. Contact the device manufacturer (Tesla for vehicle applications, or Parrot Faurecia for the FC6050W module) to obtain the firmware update to version p52 or later
  3. Apply the firmware update following the manufacturer-provided instructions for the specific hardware platform
  4. Verify that the firmware has been successfully updated to version p52 or later
  5. Confirm the vulnerability is remediated through validation testing or manufacturer verification
Caveat Firmware updates to critical components may require dealer/service center installation and could void warranties if not performed by authorized personnel
