Integer Underflow (Wrap or Wraparound) vulnerability in Renesas arm-trusted-firmware. An integer underflow in image range check calculations could lead to bypassing address restrictions and loading of images to unallowed addresses.
Weakness
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.
