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 · unedited
Improper initialization in the firmware for some Intel(R) Processors may allow a privileged user to potentially enable escalation of privilege via physical access.

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 · high confidence

This is a firmware vulnerability in Intel processors stemming from improper initialization. A privileged user with physical access to the system can potentially escalate their privileges by exploiting this initialization flaw in the processor firmware.

MitigationApply Intel-provided firmware updates for affected processors. Verify processor model against Intel's affected components list and update BIOS/firmware following vendor guidance.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify processor model
    Run 'lscpu' or 'cat /proc/cpuinfo' to display CPU information. Look for the processor model name in the output.
    Affected if The processor model matches any of these: Intel Xeon Bronze 3206r, Intel Xeon Gold 5218r, Intel Xeon Gold 5220r, Intel Xeon Gold 6208u, Intel Xeon Gold 6226r, or Intel Xeon Gold 6230r.
  2. Check processor firmware version
    Use 'dmidecode -t processor' or vendor-specific tools like Intel System Debugger or BMC/IPMI interfaces to query the processor firmware or BIOS version.
    Affected if The firmware version cannot be determined or is from an unpatched Intel processor firmware release.
  3. Identify NetApp Cloud Backup version
    Check the NetApp Cloud Backup version through the NetApp Cloud Manager interface or by querying the installed software package.
    Affected if NetApp Cloud Backup is deployed and running any version.
  4. Identify NetApp FAS/AFF system and BIOS version
    Access the NetApp storage system via SSH or the management interface and run 'system node show' or check the BIOS/firmware version through the BMC.
    Affected if The system is a NetApp FAS or AFF storage array running any BIOS version.

You are affected if your environment contains any of the listed Intel Xeon processor models or any version of NetApp Cloud Backup or NetApp FAS/AFF systems, combined with the presence of a privileged user with physical access.

Generated from the published advisory. Verify against your own configuration.

Check your environment

Paste your version and any relevant configuration and it will be compared against the affected criteria above. Do not include secrets or credentials.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Apply Intel-provided firmware updates for affected processors. Verify processor model against Intel's affected components list and update BIOS/firmware following vendor guidance.

Recommended fix Moderate confidence

Contact Intel or your system hardware vendor for processor microcode/BIOS updates containing the CVE-2021-0125 fix

  1. 1. Identify the specific Intel processor model(s) affected in your environment from the listed Xeon models (Bronze 3206r, Gold 5218r, 5220r, 6208u, 6226r, 6230r).
  2. 2. Check with your hardware vendor (Intel, Dell, HP, Lenovo, or system integrator) for available BIOS/firmware updates that address CVE-2021-0125.
  3. 3. For NetApp FAS/AFF systems, check NetApp's support portal (security.netapp.com) for Cloud Backup and BIOS firmware updates specific to your model.
  4. 4. Obtain the latest BIOS/firmware version from your vendor that includes the security fix.
  5. 5. Apply the firmware update following your vendor's recommended procedures, ensuring proper backup and maintenance window planning.
  6. 6. Verify the firmware version post-update to confirm the patch was successfully applied.
Caveat Firmware updates may require system downtime and should be tested in a non-production environment first
