An issue was discovered on Microchip RN4870 1.43 devices. An attacker within BLE radio range can cause a denial of service by sending a pair confirm message with wrong values.
The product does not validate or incorrectly validates the integrity check values or “checksums” of a message. This may prevent it from detecting if the data has been modified or corrupted in transmission.
