GPUCC-VRAM-01: Hardware VRAM encryption is in effect¶
| Property | Value |
|---|---|
| Severity | high |
| Platform | NVIDIA GPU Confidential Computing |
| Lifecycle stage | runtime |
| Trust boundary | memory |
| Assurance | report-derived |
| Mode | Passive: reads only the files and values you pass to the scan. |
What it checks¶
It passes when:
- Hardware VRAM encryption is in effect.
How to fix¶
- Run the GPU in CC-On so hardware VRAM encryption is enforced; confirm the attestation report shows memory protection active before loading weights.
After the fix, scan again: the check should report PASS.
When it is not assessed¶
SKIP:
- No --gpu-attestation-report specified; skipping check.
ERROR:
- Could not read/parse attestation report: …
