CVE-2021-34149

The Bluetooth Classic implementation on the Texas Instruments CC256XCQFN-EM does not properly handle the reception of continuous LMP_AU_Rand packets, allowing attackers in radio range to trigger a denial of service (deadlock) of the device by flooding it with LMP_AU_Rand packets after the paging procedure.
