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 Precision Rack, 14G Intel BIOS versions prior to 2.22.2, contains an Improper Input Validation vulnerability. A high privileged attacker with local access could potentially exploit this vulnerability, leading to Information disclosure.

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

Dell Precision Rack 14G Intel BIOS versions before 2.22.2 contain an improper input validation vulnerability. A high-privileged attacker with local physical or console access could potentially exploit this flaw to disclose sensitive information. The vulnerability stems from insufficient validation of input data within the BIOS firmware.

MitigationUpdate Dell Precision Rack 14G Intel BIOS to version 2.22.2 or later to remediate this vulnerability. Organizations should apply the BIOS update following Dell's documented firmware update procedures, ensuring appropriate backup and rollback capabilities are in place.

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 installed BIOS version
    During system boot, press F2 to enter BIOS setup utility and locate the BIOS version information on the main screen, or boot into Linux and run 'dmidecode -s bios-version' to retrieve the current BIOS version
    Affected if The displayed version is below 2.22.1
  2. Confirm system model
    Run 'dmidecode -s system-product-name' on Linux, check the BIOS setup utility under System Information, or locate the model label on the physical chassis to verify the system is a Dell Precision 7920 Rack or Dell 7920 Xl Rack
    Affected if The system model matches either Precision 7920 Rack or 7920 Xl Rack
  3. Check BIOS version against threshold
    Compare the installed BIOS version identified in step 1 against the affected range of versions prior to 2.22.1. Document the exact version number for comparison.
    Affected if Installed version is 2.22.0 or earlier, or any version below 2.22.1
  4. Assess physical access exposure
    Review physical security controls and console access policies to determine whether an unauthorized high-privileged attacker could gain local physical or console access to the affected system
    Affected if System is accessible to users without proper vetting, or console access is not adequately restricted

You are affected if your Dell Precision 7920 Rack or 7920 Xl Rack runs BIOS version 2.22.1 or earlier and an untrusted individual could obtain physical or console access to the system.

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 2.22.1 or later
Fixed in 2.22.1
Interim mitigation

Update Dell Precision Rack 14G Intel BIOS to version 2.22.2 or later to remediate this vulnerability. Organizations should apply the BIOS update following Dell's documented firmware update procedures, ensuring appropriate backup and rollback capabilities are in place.

Recommended fix Moderate confidence

BIOS version 2.22.2 or later for Dell Precision 7920 Rack / 7920 Xl Rack

  1. 1. Download the BIOS firmware update version 2.22.2 or later from the Dell support website (support.dell.com)
  2. 2. Locate the specific firmware file for your model: Precision 7920 Rack or 7920 Xl Rack
  3. 3. Review the update instructions provided by Dell in the firmware download page
  4. 4. Apply the BIOS firmware update following Dell's documented update process, which typically requires: a) Running the downloaded executable or creating a bootable USB, b) Following the on-screen instructions, c) Ensuring the system is connected to power and not interrupted during the update
Caveat BIOS updates carry inherent risk of system failure if interrupted; ensure stable power and follow Dell's update instructions precisely
