GPUCC-REVOKE-01: Device certificate revocation (OCSP/CRL) is checked and fails closed¶
| Property | Value |
|---|---|
| Severity | high |
| Platform | NVIDIA GPU Confidential Computing |
| Lifecycle stage | attest |
| Trust boundary | attestation |
| Assurance | operator-declared |
| Mode | Passive: reads only the files and values you pass to the scan. |
What it checks¶
It passes when:
- Verifier checks device-certificate revocation (OCSP/CRL) and fails closed.
How to fix¶
- Enable device-certificate revocation checking against NVIDIA's OCSP responder / CRL in the verifier (local Verifier or NRAS policy), and fail closed: treat an unreachable responder or unknown status as untrusted, never as valid.
- Check device-cert revocation against NVIDIA OCSP/CRL; fail closed.
After the fix, scan again: the check should report PASS.
When it is not assessed¶
SKIP:
- No --gpu-verifier-policy specified; skipping check.
ERROR:
- Could not read/parse verifier policy: …
Scan inputs¶
The untrust scan options this check reads:
| Option | Description |
|---|---|
--gpu-verifier-policy |
Verifier policy JSON: pinned RIM measurements, cert chain, revocation. |
Permissions¶
None. The check reads only the files or values you pass to the scan.
