What is GPUBreach attack?

GPUBreach is a RowHammer exploit on NVIDIA GPUs using GDDR6 memory to flip bits, corrupt page tables, and escalate privileges to full CPU root access — even with IOMMU enabled.

Does GPUBreach affect consumer GPUs?

Yes, especially non-ECC desktop and laptop NVIDIA cards with no mitigations. Cloud and HPC setups are prime targets too.

How to protect against GPU RowHammer attacks?

Enable ECC where available, patch drivers, isolate workloads, and watch for anomalous memory access patterns — but no silver bullet yet.
