GPUBreach is a GPU Rowhammer attack letting unprivileged code corrupt memory, escalate to root on CPU via NVIDIA driver flaws.

How does Rowhammer work on GPUs?

It hammers memory rows rapidly, flipping bits in adjacent ones—GDDR6's dense, fast nature amplifies it for page table corruption.

Is my NVIDIA GPU vulnerable to GPUBreach?

Likely yes, if running CUDA kernels without isolation. Await patches; enable IOMMU doesn't fully protect.
