An issue was discovered on Samsung mobile devices with O(8.x) (Qualcomm chipsets) software. There is an integer underflow in the Secure Storage Trustlet. The Samsung ID is SVE-2019-13952 (July 2019).
The product subtracts one value from another, such that the result is less than the minimum allowable integer value, which produces a value that is not equal to the correct result.
