The Bastet driver of Honor 9 Huawei smart phones with software of versions earlier than Stanford-AL10C00B175 has integer overflow vulnerability due to the lack of parameter validation. An attacker tricks a user into installing a malicious APP which has the root privilege; the APP can send a specific parameter to the driver of the smart phone, causing arbitrary code execution.
The product performs a calculation that can produce an integer overflow or wraparound when the logic assumes that the resulting value will always be larger than the original value. This occurs when an integer value is incremented to a value that is too large to store in the associated representation. When this occurs, the value may become a very small or negative number.
