CVE-2021-28155

Estado: ModificadaMedia (6.5)—

The Bluetooth Classic implementation on JBL TUNE500BT devices does not properly handle the reception of continuous unsolicited LMP responses, allowing attackers in radio range to trigger a denial of service and shutdown a device by flooding the target device with LMP Feature Response data.
