Threat Score
Researchers demonstrated new Rowhammer attacks against NVIDIA Ampere GPUs (including RTX 3060, RTX 6000, RTX A6000) that induce GDDR6 bitflips to corrupt GPU page tables and escalate to arbitrary read/write of CPU memory, allowing full system compromise and root shells; one proof-of-concept requires IOMMU disabled (default in many BIOS), while a later variant reportedly works with IOMMU enabled.
