Researchers from the University of Toronto have uncovered a Rowhammer attack called GPUThor that can induce multi-bit errors in GDDR6 memory on some NVIDIA GPUs, bypassing ECC protection limits. The attack could disable the GPU or, according to the researchers, enable an unprivileged CUDA program to gain arbitrary memory access and open a root session on the host system.
