FACEB13D exploit: Liberating the A100 beast inside Nvidia’s CMP 170HX e-waste
Petri Krohn
We have been able to unlock the full 200 TFLOPS of compute performance and all 64GB of the usable HBM2e memory of the CMP 170HX, a severely restricted crypto-mining variant of the Nvidia A100 GPU accelerator. The exploit is based on guessing the debug AES key and creating a ROP chain and payload from the decrypted and disassembled booter_load code, a Falcon μcode module with a overflow vulnerability.
