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 in the Bluetooth RFCOMM service of Parani M10 Motorcycle Intercom v2.1.3 allows unauthorized attackers to cause a Denial of Service (DoS) via supplying crafted RFCOMM frames.

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 Denial of Service vulnerability exists in the Bluetooth RFCOMM service of Parani M10 Motorcycle Intercom v2.1.3. Attackers can send specially crafted RFCOMM frames to trigger the DoS condition, causing the device's Bluetooth functionality to become unresponsive or crash.

MitigationContact Parani for firmware updates addressing this vulnerability. If no update is available, reduce attack surface by disabling Bluetooth when not in use and avoiding pairing with untrusted devices.

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 device model
    Locate the physical Parani M10 intercom unit or check product documentation/packaging. Confirm the device is a Parani M10 Motorcycle Intercom.
    Affected if The device is NOT a Parani M10 - if it is a different model, this specific CVE does not apply.
  2. Check the firmware version
    Access the Parani M10 firmware settings through the device menu, companion mobile app, or check the product label/ documentation. Locate the firmware version number.
    Affected if The firmware version is 2.1.3 or lower (e.g., 2.1.2, 2.1.1, 2.1.0, etc.). Versions prior to the fix are affected.
  3. Confirm Bluetooth RFCOMM availability
    Verify that Bluetooth functionality is enabled on the Parani M10. As an intercom device, RFCOMM is typically active by default for device pairing and communication.
    Affected if Bluetooth is enabled and the device is in discoverable/pairing mode - the RFCOMM service is active and reachable.
  4. Assess Bluetooth exposure
    Determine whether the device is paired with untrusted devices or remains discoverable in public/high-risk areas where attackers could send malicious RFCOMM frames.
    Affected if The device Bluetooth is active and accessible to untrusted or unknown devices within range.

You are affected if you own a Parani M10 Motorcycle Intercom running firmware version 2.1.3 or lower with Bluetooth functionality enabled.
