CVE-2022-42286
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 · uneditedDGX A100 SBIOS contains a vulnerability in Bds, which may lead to code execution, denial of service, or escalation of privileges.
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 System BIOS contains a vulnerability in the Bds (Boot Device Selection) component. This firmware-level flaw may allow a local attacker to achieve code execution, cause denial of service, or escalate privileges on the affected system.
Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

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 system is NVIDIA DGX A100Identify the system model through system information utilities, dmidecode output, or physical system labelsAffected if System is not an NVIDIA DGX A100 (this CVE only applies to that specific platform)
-
Access BIOS version informationEnter the system BIOS setup utility during boot or use system management commands such as dmidecode -s bios-version, or NVIDIA system management tools for the DGX A100Affected if Unable to retrieve BIOS version information
-
Compare installed SBIOS version to vulnerable rangeLocate the SBIOS firmware version string from the BIOS utility or management interface and compare numerically against version 1.18Affected if Installed SBIOS version is less than 1.18 (for example, 1.17, 1.16, etc.)
-
Verify Bds component is accessibleConfirm the Boot Device Selection (Bds) functionality is present and accessible on the systemAffected if Bds component is present and could be exploited by a local attacker
A system is affected if it is an NVIDIA DGX A100 with SBIOS firmware version below 1.18, as the vulnerability exists in the Bds component of those versions.
Generated from the published advisory. Verify against your own configuration.
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 · scoped1.18
Apply the NVIDIA-supplied SBIOS firmware update for the DGX A100 once available. Verify the current firmware version and test updates in a non-production environment before deployment.
Sbios 1.18 or later
- Contact NVIDIA support via nvidia.custhelp.com to obtain the SBIOS version 1.18 firmware update for DGX A100
- Follow NVIDIA's documented SBIOS firmware update procedure for DGX A100 systems
- Ensure the firmware update is applied during a planned maintenance window as firmware flashes can render the system unusable if interrupted
- Verify the SBIOS version after update confirms 1.18 or later is installed
