CVE-2022-42274
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 BMC contains a vulnerability in IPMI handler, where an authorized attacker can cause a buffer overflow and cause a denial of service or gain code execution.
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 confidenceBuffer overflow vulnerability in NVIDIA BMC IPMI handler allows an authorized attacker to cause denial of service or achieve code execution via the overflowed buffer.
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 NVIDIA BMC is presentRun `ipmitool mc info` or check the BMC web interface. Look for 'NVIDIA' or 'Nvidia' in the manufacturer or product name fields.Affected if The system uses an NVIDIA Baseboard Management Controller for IPMI management.
-
Retrieve BMC firmware versionUse `ipmitool mc info` to display BMC information, or access the BMC web interface and navigate to the Firmware/Version information page. Identify the firmware or BMC version number displayed.Affected if A BMC firmware version is shown (e.g., 00.19.06, 00.20.00, etc.).
-
Compare version against affected rangeCompare the installed BMC firmware version number to the vulnerable range. Versions below 00.19.07 (such as 00.19.06, 00.18.x, etc.) are affected. Versions 00.19.07 and above are not vulnerable.Affected if The installed BMC firmware version is less than 00.19.07 (e.g., 00.19.06, 00.19.00, 00.18.XX).
If the system has an NVIDIA BMC with firmware version below 00.19.07, the environment is affected by this vulnerability.

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 · scoped00.19.07
Apply NVIDIA firmware update for the BMC to patch the vulnerable IPMI handler code; verify update in staging before production deployment.
BMC firmware version 00.19.07 or later
- Identify the specific NVIDIA BMC device model in your environment
- Download the BMC firmware version 00.19.07 or later from NVIDIA's official support portal (nvidia.custhelp.com)
- Verify the firmware integrity using checksums provided by NVIDIA
- Follow NVIDIA's standard BMC firmware update procedure - typically involves uploading the firmware through the BMC web interface or IPMI interface
- Ensure the BMC firmware update process completes successfully and the device reboots
- After update, verify the running firmware version is 00.19.07 or later to confirm the remediation
