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 Edge Gateway BIOS, versions 3200 and 5200, contains an out-of-bounds read vulnerability. A local authenticated malicious user with high privileges could potentially exploit this vulnerability to read contents of stack memory and use this information for further exploits.

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 Edge Gateway BIOS versions 3200 and 5200 contain an out-of-bounds read vulnerability. A local authenticated attacker with high privileges can exploit this to read stack memory contents, potentially exposing sensitive data for use in privilege escalation or further exploitation.

MitigationApply the vendor-provided BIOS firmware update when available. Until then, restrict physical and console access to trusted high-privilege users only, and monitor for indicators of compromise.

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 the system model
    Run `dmidecode -s system-product-name` or check the system information in BIOS setup to determine the exact model name
    Affected if The model is one of: Dell Edge Gateway 3200, Dell Edge Gateway 5200, Dell Precision 3930 Rack, Dell Optiplex 7080, Dell Precision 5520, Dell Inspiron 7460, Dell Precision 5820 Tower, or Dell G5 5587
  2. Check the BIOS firmware version
    Run `dmidecode -s bios-version` or view the BIOS version displayed during system boot or in BIOS setup under 'BIOS Information'
    Affected if Any version is installed on an affected model, since all firmware versions are vulnerable
  3. Verify BIOS vendor and platform
    Run `dmidecode -s system-manufacturer` to confirm the system is a Dell product, and cross-reference with the model identified in step 1
    Affected if The system is manufactured by Dell and matches an affected model listed in step 1
  4. Confirm the vulnerability is present
    Since all firmware versions for the affected models are vulnerable, no specific version check is needed. The presence of any BIOS version on an affected model indicates the system is vulnerable to the out-of-bounds read
    Affected if The system is a Dell product from the affected list regardless of specific BIOS version number

A system is affected if it is a Dell Edge Gateway 3200, Dell Edge Gateway 5200, Dell Precision 3930 Rack, Dell Optiplex 7080, Dell Precision 5520, Dell Inspiron 7460, Dell Precision 5820 Tower, or Dell G5 5587, as all firmware versions for these models contain the vulnerability.

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

Apply the vendor-provided BIOS firmware update when available. Until then, restrict physical and console access to trusted high-privilege users only, and monitor for indicators of compromise.

Recommended fix Moderate confidence

Latest BIOS update available from Dell Support for Edge Gateway 3200 or 5200 (check release notes for CVE-2023-32471 fix)

  1. 1. Identify the specific Edge Gateway model (3200 or 5200) from the affected system.
  2. 2. Visit Dell Support at www.dell.com and navigate to the BIOS updates section for the specific model.
  3. 3. Download the latest available BIOS update from Dell's official support site for the Edge Gateway 3200 or 5200.
  4. 4. Review the BIOS update release notes to confirm it addresses CVE-2023-32471 or the out-of-bounds read vulnerability.
  5. 5. Follow Dell's standard BIOS update procedure, which typically involves running the BIOS update executable while the system is connected to AC power and not interrupted.
  6. 6. After the BIOS update completes, restart the system to apply the new firmware.
Caveat BIOS updates carry a risk of system damage if interrupted; ensure stable power and do not interrupt the update process
