In all android releases (Android for MSM, Firefox OS for MSM, QRD Android) from CAF using the linux kernel, while loading a user application in qseecom, an integer overflow could potentially occur if the application partition size is rounded up to page_size.
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.
