CVE-2022-31599
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedNVIDIA DGX A100 contains a vulnerability in SBIOS in the Ofbd, where a local user with elevated privileges can cause access to an uninitialized pointer, which may lead to code execution, escalation of privileges, denial of service, and information disclosure. The scope of impact can extend to other components.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceNVIDIA DGX A100 contains an uninitialized pointer vulnerability in the SBIOS component within the Ofbd (likely firmware management layer). A local user with elevated privileges can trigger dereference of this uninitialized pointer, potentially achieving code execution, privilege escalation, denial of service, or information disclosure. The vulnerability's impact may propagate to other system components.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Confirm the system is an NVIDIA DGX A100Run the command 'lspci | grep -i nvidia' or check system documentation/labels to verify the hardware model is specifically an NVIDIA DGX A100 system.Affected if The system is not an NVIDIA DGX A100 - other NVIDIA products or non-NVIDIA systems are not affected by this specific CVE.
-
Identify the SBIOS firmware versionAccess the SBIOS (System BIOS) interface during boot (typically via F2 or Del key) and navigate to the firmware information page, or run 'dmidecode -s bios-version' if available on the system.Affected if The displayed SBIOS firmware version is lower than 22.5.5 (for example, 22.4.0, 21.x.x, or earlier).
-
Verify the Ofbd component is presentCheck system firmware documentation or run 'dmidecode' to see if the Ofbd (NVIDIA firmware management layer) component is listed as part of the system firmware.Affected if The Ofbd firmware management layer is present and running on the system - the vulnerability exists specifically within this component.
-
Check for elevated local accessReview system audit logs and user account configurations to identify if any untrusted local users have elevated privileges (sudo, root, or administrator access).Affected if Untrusted or unauthorized local users have elevated privileges on the system - this is required to trigger the uninitialized pointer dereference.
A system is affected if it is an NVIDIA DGX A100 with SBIOS firmware version below 22.5.5 that has the Ofbd component active and untrusted users with elevated local privileges.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped22.5.5
Apply NVIDIA's patched SBIOS firmware update for DGX A100 when released, or contact NVIDIA enterprise support for remediation. Restrict privileged local access to trusted administrators as an interim compensating control.
22.5.5
- Verify current DGX A100 firmware version using NVIDIA system management tools or BMC interface
- Download firmware version 22.5.5 or later from NVIDIA's official support portal (nvidia.custhelp.com)
- Review NVIDIA firmware upgrade documentation for DGX A100 systems
- Apply firmware update following NVIDIA's recommended upgrade procedure, ensuring stable power and proper shutdown
- Verify successful installation by confirming new firmware version
