Cybersecurity researchers at the University of Toronto have achieved a breakthrough in hardware-level attacks by successfully demonstrating GPUHammer, the first Rowhammer attack specifically targeting discrete NVIDIA GPUs.
The research, which focuses on the popular NVIDIA A6000 GPU with GDDR6 memory, represents a significant expansion of the decade-old Rowhammer vulnerability beyond traditional CPU memories.
The research team, led by Chris S. Lin, Joyce Qu, and Gururaj Saileshwar, overcame substantial technical challenges to achieve what was previously thought impossible.
Their GPUHammer attack successfully induced 8-bit flips across 4 DRAM banks on the A6000 GPU, demonstrating that Graphics-DDR (GDDR) memories are indeed vulnerable to the same disturbance attacks that have plagued CPU memories for years.
