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 function responsible for handling BLE connection responses does not verify whether a response is expected—that is, whether the device has initiated a connection request. Instead, it relies solely on identifier matching.

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.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.

dbcve · scoped
Upgrade available Upgrade to a release after 4.1.0
Recommended fix Moderate confidence

Zephyr > 4.1.0 (subsequent patch release containing the BLE fix)

  1. 1. Identify the Zephyr version currently in use by checking the manifest file (west.yml) or the Zephyr kernel version at runtime
  2. 2. Update the Zephyr manifest to use a version later than 4.1.0 that includes the security fix for this BLE connection validation issue
  3. 3. Rebuild the firmware with the updated Zephyr version
  4. 4. Flash the updated firmware to the affected devices
  5. 5. Test BLE connectivity to confirm normal operation after the update
Caveat Review release notes for any BLE stack API changes between current version and target version; minor API changes may require code adjustments
