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 during SMM.

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 has an improper input validation vulnerability that allows a local authenticated attacker to use a System Management Interrupt (SMI) to achieve arbitrary code execution in System Management Mode (SMM). SMM operates at the highest privilege level, making this a serious firmware-level flaw despite the medium CVSS score.

MitigationApply the Dell BIOS firmware update for affected systems. Restrict physical access and ensure proper authentication controls are in place to prevent unauthorized local access until the patch is deployed.

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 your Dell system model
    Check the system label, BIOS startup screen, or use system information utilities (dmidecode -s system-product-name on Linux, or systeminfo on Windows) to confirm the exact model number
    Affected if The model is not one of the listed affected products (Dell G5 5505, Inspiron 22 3275, Inspiron 24 3475, Inspiron 27 7775, Inspiron 3180, Inspiron 3185, Inspiron 3195, or Inspiron 3505)
  2. Determine the installed BIOS firmware version
    Access the BIOS setup (press F2 at startup), or retrieve via command line: dmidecode -s bios-version on Linux, wmic bios get version on Windows, or Dell SupportAssist/Update utility
    Affected if Unable to retrieve a version number - the system may be running an older or custom BIOS that does not report version information standardly
  3. Compare your firmware version against affected thresholds
    Cross-reference the installed version with the vulnerable version thresholds: G5 5505 < 1.10.0, Inspiron 22 3275 < 1.8.0, Inspiron 24 3475 < 1.8.0, Inspiron 27 7775 < 2.15.0, Inspiron 3180/3185 < 1.4.4, Inspiron 3195 < 1.4.1, Inspiron 3505 < 1.5.0
    Affected if Your installed version is lower than the threshold listed for your specific model (e.g., G5 5505 on 1.5.0 is affected, but 1.10.0 or higher is not)
  4. Verify the attacker would need local authenticated access
    Confirm this vulnerability requires a local authenticated attacker - the system must already be accessible with valid credentials to log into the operating system
    Affected if Your system is not protected by login authentication or allows unauthorized physical access to untrusted individuals

You are affected if you own a Dell G5 5505, Inspiron 22 3275, Inspiron 24 3475, Inspiron 27 7775, Inspiron 3180, Inspiron 3185, Inspiron 3195, or Inspiron 3505 and your current BIOS firmware version is below the version threshold listed for your model.

dbcve · scoped
Upgrade available Upgrade to 1.4.1 / 1.4.4 / 1.5.0 or later
Fixed in 1.4.11.4.41.5.0
Interim mitigation

Apply the Dell BIOS firmware update for affected systems. Restrict physical access and ensure proper authentication controls are in place to prevent unauthorized local access until the patch is deployed.

Recommended fix High confidence

Firmware version 1.10.0 (G5 5505), 1.8.0 (Inspiron 22 3275/24 3475), 2.15.0 (Inspiron 27 7775), 1.4.4 (Inspiron 3180/3185), 1.4.1 (Inspiron 3195), or 1.5.0 (Inspiron 3505)

  1. Identify the exact Dell model from the affected product list (G5 5505, Inspiron 22 3275, Inspiron 24 3475, Inspiron 27 7775, Inspiron 3180, Inspiron 3185, Inspiron 3195, or Inspiron 3505)
  2. Navigate to Dell support website (www.dell.com) and locate the BIOS update page for the specific model
  3. Download the BIOS firmware update: version 1.10.0 for G5 5505; 1.8.0 for Inspiron 22 3275 and Inspiron 24 3475; 2.15.0 for Inspiron 27 7775; 1.4.4 for Inspiron 3180 and Inspiron 3185; 1.4.1 for Inspiron 3195; 1.5.0 for Inspiron 3505
  4. Connect the system to AC power and ensure the update process will not be interrupted
  5. Run the Dell BIOS update utility and follow the on-screen instructions to flash the BIOS
  6. Allow the system to restart and complete the BIOS update process
Caveat BIOS updates carry a risk of system brick if interrupted; ensure stable power and do not interrupt the flashing process
