GDDR6 GPUs Allow Root Access via Rowhammer
Researchers on Apr 4, 2026 revealed two new Rowhammer GPU attacks, GDDRHammer and GeForge, that induce bit flips in GDDR6 memory and can map GPU page tables to CPU memory to gain root access. Tests produced 1,171 flips on an RTX 3060 and 202 flips on an RTX A6000, affecting most tested GDDR6 cards. Recommended mitigations include enabling ECC or IOMMU to sandbox GPUs.
Scoring Rationale
High score because the research demonstrates a novel, high-impact attack vector achieving CPU root via GDDR6 Rowhammer with concrete flip counts and broad device coverage. Score reflects strong novelty, wide scope, and actionable mitigations; tempered slightly by reliance on a single research disclosure and media report despite same-day timeliness.
