CVE-2026-97402

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.
