CVE-2024-22429
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 · uneditedDell BIOS contains an Improper Input Validation vulnerability. A local authenticated malicious user with admin privileges could potentially exploit this vulnerability, leading to arbitrary code execution.
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 confidenceDell BIOS contains an improper input validation vulnerability that allows a local authenticated user with admin privileges to execute arbitrary code. The vulnerability exists in the BIOS firmware input handling mechanisms, potentially allowing crafted input to bypass validation checks and execute code at the firmware level with high privileges.

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 checksWork through these to decide whether this CVE applies to you.
-
Identify the Dell system modelRun 'dmidecode -s system-product-name' on Linux or check System Information on Windows to confirm the exact model numberAffected if The model is one of: Dell Edge Gateway 5000, Dell Edge Gateway 3000, Dell Embedded Box PC 3000, Dell Embedded Box PC 5000, Dell Precision 5820 Tower, Dell Latitude 12 Rugged Extreme 7214, Dell Latitude 13 3380, or Dell Latitude 3180
-
Check the installed BIOS firmware versionRun 'dmidecode -s bios-version' on Linux, or open System Information on Windows and check the BIOS version field under 'BIOS Version' or 'BIOS Information'Affected if A BIOS version number is retrieved from the system
-
Compare the BIOS version against the vulnerability thresholdsCompare the installed BIOS version to the following thresholds: Edge Gateway 5000 < 1.28.0, Edge Gateway 3000 < 1.18.0, Embedded Box PC 3000 < 1.24.0, Embedded Box PC 5000 < 1.25.0, Precision 5820 Tower < 2.36.0, Latitude 12 Rugged Extreme 7214 < 1.46.0, Latitude 13 3380 < 1.27.0, Latitude 3180 < 1.29.0Affected if The installed BIOS version is lower than the threshold for that specific model (for example, 1.25.0 on an Edge Gateway 5000 would be vulnerable, while 1.30.0 would not)
You are affected if your system matches one of the listed Dell models AND its current BIOS firmware version is below the version threshold specified for that model.

dbcve · scoped1.18.01.24.01.25.0
Apply Dell's BIOS/firmware updates to affected systems. Until patched, limit admin privilege assignment and monitor for unauthorized BIOS modifications.
BIOS firmware version equal to or greater than: 1.28.0 (Edge Gateway 5000), 2.36.0 (Precision 5820), 1.18.0 (Edge Gateway 3000), 1.24.0 (Embedded Box PC 3000), 1.25.0 (Embedded Box PC 5000), 1.46.0 (Latitude 12 Rugged Extreme 7214), 1.27.0 (Latitude 13 3380), 1.29.0 (Latitude 3180)
- Identify the exact Dell device model from the affected product list
- Visit Dell Support at www.dell.com and navigate to the drivers and downloads section for your specific device
- Download the latest BIOS/firmware version from Dell's support site: Edge Gateway 5000 requires 1.28.0, Edge Gateway 3000 requires 1.18.0, Embedded Box PC 3000 requires 1.24.0, Embedded Box PC 5000 requires 1.25.0, Precision 5820 Tower requires 2.36.0, Latitude 12 Rugged Extreme 7214 requires 1.46.0, Latitude 13 3380 requires 1.27.0, Latitude 3180 requires 1.29.0
- Backup current BIOS settings if possible
- Ensure the laptop/desktop is connected to AC power and will not lose power during the update process
- Run the Dell BIOS update utility and follow the on-screen instructions to flash the new firmware
- Allow the system to reboot and complete the BIOS update - do not interrupt this process
- After the update completes, verify the BIOS version matches the target fixed version
