# Eclipse Kura: crafted BLE beacon packet halts gateway beacon scanning

Link for people: https://infrastack.ai/live/CVE-2026-97402 (this .md is for agents)

Eclipse Kura's iBeacon and Eddystone decoders misparse the length field of BLE advertisements, so a two-byte broadcast sends the beacon scanner into an infinite loop. An attacker within Bluetooth range can pin a CPU core and stop beacon ingestion until the gateway restarts.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Check whether the iBeacon/Eddystone scanner component is installed and enabled in the Kura gateway configuration (the sources say it is not installed or enabled by default).
- Check the installed Kura version: affected versions are `3.1.0` through `5.6.2`.

## From the sources

In Eclipse Kura versions 3.1.0 to 5.6.2, the iBeacon and Eddystone advertisement decoders wrongly parse the AD-structure length field of an over-the-air BLE advertising payload. Any unauthenticated attacker within BLE radio range can broadcast a two-byte advertising payload that drives the Kura beacon-scanner thread into a tight infinite loop, pinning a CPU core and permanently halting beacon ingestion until the gateway is restarted. To trigger the attack, the iBeacon/Eddystone scanner component should be installed and active. By default the components are not installed or enabled.
