TI’s BLE stack caches and reuses the LTK’s property for a bonded mobile. A LTK can be an unauthenticated-and-no-MITM-protection key created by Just Works or an authenticated-and-MITM-protection key created by Passkey Entry, Numeric Comparison or OOB. Assume that a victim mobile uses secure pairing to pair with a victim BLE device based on TI chips and generate an authenticated-and-MITM-protection LTK. If a fake mobile with the victim mobile’s MAC address uses Just Works and pairs with the victim device, the generated LTK still has the property of authenticated-and-MITM-protection. Therefore, the fake mobile can access attributes with the authenticated read/write permission. • http://software-dl.ti.com/simplelink/esd/simplelink_cc13x2_26x2_sdk/3.20.00.68/exports/changelog.html https://www.usenix.org/system/files/sec20-zhang-yue.pdf • CWE-863: Incorrect Authorization •

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. Una implementación de Bluetooth Classic en el Texas Instruments CC256XCQFN-EM, no maneja apropiadamente la recepción de paquetes LMP_AU_Rand continuos, permitiendo a atacantes en el rango de radio desencadenar una denegación de servicio (deadlock) del dispositivo inundándolo con paquetes LMP_AU_Rand después del procedimiento de paginación • https://dl.packetstormsecurity.net/papers/general/braktooth.pdf https://www.ti.com/product/CC2564C https://www.ti.com/tool/CC256XC-BT-SP#primary-sw •
