Nvidia knew about this since November.
GPUBreach, a Rowhammer attack on GDDR6 memory that flips bits, corrupts GPU page tables, and with unpatched driver bugs, gives attackers root shell access to the entire system.
This isn't theoretical. It works remotely. Any user with GPU permissions can exploit it.
And here's the problem: Nvidia GPUs run the world's AI. ChatGPT, Claude, Gemini, all on Nvidia hardware. Cloud services, research clusters, every serious AI deployment.
A vulnerability in the GPU layer is a vulnerability in AI infrastructure itself.
Ironically, this dropped the same week Anthropic announced a model too dangerous to release, one that finds vulnerabilities in software. The irony isn't lost.
AI is powerful. AI infrastructure is fragile.
