An integer underflow in the DDS loader of Blender leads to an out-of-bounds read, possibly allowing an attacker to read sensitive data using a crafted DDS image file. This flaw affects Blender versions prior to 2.83.19, 2.93.8 and 3.1.
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.
