NVIDIA GPUs Vulnerable to GPUThor Rowhammer Attack Bypassing ECC

NVIDIA GPUs are vulnerable to a new type of attack, dubbed GPUThor, which can cause massive corruption - up to 377,552 bit flips per gigabyte - on certain models, including the RTX A5000, when their GDDR6 memory is exploited. This Rowhammer-style attack can bypass ECC protection, putting powerful NVIDIA workstation cards at risk.
