The Bluetooth Low Energy Secure Manager Protocol (SMP) implementation in Texas Instruments SimpleLink SIMPLELINK-CC2640R2-SDK through 2.2.3 allows the Diffie-Hellman check during the Secure Connection pairing to be skipped if the Link Layer encryption setup is performed earlier. An attacker in radio range can achieve arbitrary read/write access to protected GATT service data, cause a denial of service, or possibly control a device's function by establishing an encrypted session with an unauthenticated Long Term Key (LTK).

Texas Instruments CC256x and WL18xx dual-mode Bluetooth controller devices, when LE scan mode is used, allow remote attackers to trigger a buffer overflow via a malformed Bluetooth Low Energy advertising packet, to cause a denial of service or potentially execute arbitrary code. This affects CC256xC-BT-SP 1.2, CC256xB-BT-SP 1.8, and WL18xx-BT-SP 4.4.

Flawed SK_LOAD module authenticity check in Texas Instruments OMAP L138

The Texas Instruments OMAP L138 (secure variants) trusted execution environment (TEE) performs an RSA check implemented in mask ROM when loading a module through the SK_LOAD routine. However, only the module header authenticity is validated. An adversary can re-use any correctly signed header and append a forged payload, to be encrypted using the CEK (obtainable through CVE-2022-25332) in order to obtain arbitrary code execution in secure context. This constitutes a full break of the TEE security architecture.
