Rowhammer attack threatens NVIDIA Ampere GPUs and host systems.

Researchers have demonstrated a Rowhammer-style technique that flips bits in GDDR on NVIDIA Ampere GPUs to corrupt CPU memory via DMA, enabling full host compromise when IOMMU is disabled. Independent teams reproduced the attack on two Ampere cards. The approach targets host systems that pair these GPUs with default BIOS settings where IOMMU is off, broadening exposure even without a kernel or driver bug. There are no CVEs and no evidence of in-the-wild exploitation. This is a follow-up to earlier reporting on the same developing issue. Inventory Ampere GPUs, verify and enable IOMMU in BIOS/UEFI, restrict untrusted GPU workloads, and validate BIOS defaults across fleets—especially in manufacturing and other GPU-accelerated environments.
