New Rowhammer attacks give complete control of machines running Nvidia GPUs

In tests, the technique achieved a bit-flip success rate of 89% on GDDR6X memory, turning graphics cards into a Trojan horse for system compromise. This attack exploits electrical interference in dense memory cells, requiring no physical access and bypassing standard protections, making it 40% more efficient at triggering errors than the average Rowhammer variant on consumer hardware.
