New GPUThor attack defeats NVIDIA ECC protection for root access #cybersecurity #hacking #news #infosec #security #technology #privacy
University of Toronto researchers built GPUThor, a Rowhammer attack that bypasses NVIDIA's ECC and Target Row Refresh protections to achieve root access 1,200x faster than GPUHammer.

GPUThor Attack Bypasses ECC to Achieve Root Access on NVIDIA GPUs
NVIDIA graphics cards employ specialized error-correcting memory capable of detecting and repairing random data corruption on its own. A new attack called GPUThor has demonstrated that even this protection can be circumvented, leading to memory corruption, GPU failure, and privilege escalation all the way up to root. Tested Across Multiple Ampere-Generation GPUs Researchers at the University of Toronto tested GPUThor against Ampere-generation graphics cards equipped with GDDR6 memory, including the RTX A4000, RTX A4500, RTX A5000, and RTX A6000.
