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
Dell PowerEdge Server BIOS and Dell Precision Workstation 7910 and 7920 Rack BIOS contain an Improper SMM communication buffer verification vulnerability. A Local High Privileged attacker could potentially exploit this vulnerability leading to arbitrary writes or denial of service.

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 confidence

This vulnerability in Dell PowerEdge servers and Precision Workstation 7910/7920 Rack systems involves improper verification of System Management Mode (SMM) communication buffers. SMM operates at the highest privilege level on x86 processors, and the insufficient buffer validation could allow a local attacker with high privileges to perform arbitrary memory writes or cause a denial of service.

MitigationApply the Dell BIOS/firmware update for affected PowerEdge servers and Precision Workstation models to remediate this vulnerability. Since the update requires BIOS modification, plan for appropriate maintenance windows and follow Dell's firmware update procedures.

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 the exact Dell server or workstation model
    Check the physical label on the chassis or access iDRAC web interface or run 'racadm getsysinfo' via iDRAC to confirm the exact model number (R6415, R7415, R7425, R730, R730xd, R630, C4130, M630, or Precision 7910/7920 Rack)
    Affected if Model is one of the listed affected products
  2. Retrieve the current firmware version
    Access iDRAC web interface under Firmware > BIOS, or use 'racadm getversion' command via iDRAC/Lifecycle Controller, or check within BIOS setup under System Information > BIOS Version
    Affected if Firmware version cannot be determined or is below the safe version
  3. Compare installed version against affected ranges
    For R6415/R7415/R7425 models: verify firmware is below 1.18.0. For R730/R730xd/R630/C4130/M630 models: verify firmware is below 2.14.0. Note the exact version number displayed in iDRAC or BIOS
    Affected if Installed version is less than 1.18.0 (R6415/R7415/R7425) or less than 2.14.0 (R730/R730xd/R630/C4130/M630)
  4. Check if iDRAC/Lifecycle Controller is accessible
    Verify network access to iDRAC interface or confirm Lifecycle Controller is available on next boot - this is the primary channel for firmware version verification and updates
    Affected if Cannot access iDRAC or Lifecycle Controller to verify firmware version

You are affected if your server model matches one of the listed products AND the installed firmware version is below 1.18.0 for R6415/R7415/R7425 or below 2.14.0 for R730/R730xd/R630/C4130/M630.

Interim mitigation

Apply the Dell BIOS/firmware update for affected PowerEdge servers and Precision Workstation models to remediate this vulnerability. Since the update requires BIOS modification, plan for appropriate maintenance windows and follow Dell's firmware update procedures.

Recommended fix Moderate confidence

R6415/R7415/R7425: Firmware 1.18.0 | R730/R730xd/R630/C4130/M630: Firmware 2.14.0

  1. 1. Identify the specific PowerEdge model from the affected list (R6415, R7415, R7425, R730, R730xd, R630, C4130, or M630)
  2. 2. Determine the current firmware version by accessing the iDRAC web interface or running 'racadm get BIOS.SysInformation' command
  3. 3. Download the firmware update from Dell's support website (www.dell.com) - search for the specific model and 'BIOS update'
  4. 4. For iDRAC-capable servers, upload the .exe or .dmg BIOS update file via the iDRAC web interface under 'Maintenance > System Update'
  5. 5. Alternatively, use the Dell Update Package (DUP) executable to apply the update from within the operating system
  6. 6. Reboot the server to complete the firmware update process
  7. 7. Verify the new BIOS firmware version is 1.18.0 or higher for R6415/R7415/R7425, or 2.14.0 or higher for R730/R730xd/R630/C4130/M630
Caveat Firmware updates may require server downtime; ensure proper planning for production environments
