GDDRHammer and GeForge attacks distort GPU memory to access all CPU memory
Researchers from several universities in the USA and Australia have developed two Rowhammer-class attacks — GDDRHammer and GeForge — that allow for bit-flipping in GDDR memory chips when running unprivileged CUDA kernel on NVIDIA GPUs. Unlike the GPUHammer method introduced last year, the new attacks are not limited to affecting data processed in GPU memory, but allow for […]
