What is GPUBreach and how does it work?

GPUBreach uses Rowhammer on GPU GDDR6 to flip bits in page tables, granting arbitrary memory access, then exploits NVIDIA driver bugs for full system root—IOMMU intact.

Does GPUBreach affect consumer NVIDIA GPUs?

Yes, especially non-ECC models like RTX series. No full mitigations yet; ECC helps but isn't foolproof against multi-bit flips.

How can I protect my AI training setup from Rowhammer attacks?

Enable System Level ECC if available (enterprise GPUs), audit CUDA code, monitor for unusual memory patterns, and await NVIDIA patches post-April disclosure.
