Huawei Mate 9 Pro smartphones with software LON-AL00BC00B139D; LON-AL00BC00B229 have an integer overflow vulnerability. The camera driver does not validate the external input parameters and causes an integer overflow, which in the after processing results in a buffer overflow. An attacker tricks the user to install a crafted application, successful exploit could cause malicious 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.
