Technical details
An integer overflow vulnerability in the GPU DDK shader compiler occurs when arithmetic operations on values derived from shader program code fail to properly prevent overflow, causing incorrect memory size calculations. This leads to memory allocation failures and subsequent NULL pointer dereferences at controlled offsets when allocation failures are not properly handled. The vulnerability is triggered by loading unusual GPU shader code from web pages into the compiler process.
