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 BIOS contains an improper input validation vulnerability. A local authenticated malicious user may potentially exploit this vulnerability by using an SMI to gain arbitrary code execution in SMRAM.

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

Dell BIOS contains an improper input validation vulnerability where a local authenticated attacker with privileges to execute code can trigger a System Management Interrupt (SMI) to achieve arbitrary code execution in SMRAM (System Management RAM). This exploits the BIOS/UEFI firmware's failure to properly validate inputs before processing them in System Management Mode (SMM), allowing privilege escalation to the highest CPU privilege level.

MitigationApply the Dell BIOS firmware update to address the input validation flaw. Restrict physical access and limit local administrative privileges to reduce attack surface. Verify the patch through vendor channels before deployment.

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 system model
    Run 'sudo dmidecode -s system-product-name' on Linux or check System Information on Windows to confirm the system is one of: Dell Edge Gateway 3000, Dell Edge Gateway 5000, or Dell Embedded Box PC 3000
    Affected if The system model does not match one of the three affected products, then it is not vulnerable to this specific CVE
  2. Retrieve the installed BIOS firmware version
    On Linux, run 'sudo dmidecode -s bios-version'. On Windows, run 'wmic bios get smbiosbiosversion' or view the version in System Information (press Win+R, type 'msinfo32', look for BIOS Version)
    Affected if Unable to retrieve the BIOS version indicates a detection limitation, not necessarily not affected
  3. Compare the installed version against the vulnerable thresholds
    For Dell Edge Gateway 3000: check if version is below 1.9.0. For Dell Edge Gateway 5000: check if version is below 1.19.0. For Dell Embedded Box PC 3000: check if version is below 1.15.0. Note that version formats may vary (e.g., 1.8.0 vs 1.08.00)
    Affected if The installed BIOS version is lower than the threshold for your specific model (3000/5000 gateway or embedded PC)

You are affected if your system is a Dell Edge Gateway 3000, 5000, or Embedded Box PC 3000 and the installed BIOS firmware version is below 1.9.0, 1.19.0, or 1.15.0 respectively.

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 · scoped
Upgrade available Upgrade to 1.9.0 / 1.15.0 / 1.19.0 or later
Fixed in 1.9.01.15.01.19.0
Interim mitigation

Apply the Dell BIOS firmware update to address the input validation flaw. Restrict physical access and limit local administrative privileges to reduce attack surface. Verify the patch through vendor channels before deployment.

Recommended fix Moderate confidence

Edge Gateway 3000: firmware 1.9.0+ | Edge Gateway 5000: firmware 1.19.0+ | Embedded Box PC 3000: firmware 1.15.0+

  1. Identify the specific Dell Edge Gateway or Embedded Box PC model in your environment
  2. Navigate to www.dell.com and locate the support/drivers section for your specific model
  3. Download the BIOS firmware update - for Edge Gateway 3000 use version 1.9.0 or later, for Edge Gateway 5000 use version 1.19.0 or later, for Embedded Box PC 3000 use version 1.15.0 or later
  4. Review Dell's BIOS update documentation for your specific hardware model
  5. Apply the BIOS firmware update following Dell's recommended procedure, which typically involves running the BIOS update utility from within the operating system or using the BIOS/UEFI flash utility
  6. Reboot the system to complete the firmware update process
  7. Verify the BIOS version has been updated to the fixed release after reboot
Caveat BIOS updates carry inherent risks; power interruption during update can brick the device; verify backup of critical data and ensure stable power supply before applying
