CVE-2024-42425
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 Precision Rack, 14G Intel BIOS versions prior to 2.22.2, contains an Access of Memory Location After End of Buffer vulnerability. A low 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 · high confidenceThis is a BIOS firmware vulnerability in Dell Precision Rack 14G systems where the BIOS code performs an out-of-bounds memory read, accessing memory locations beyond the end of a defined buffer. A low-privileged local attacker could exploit this to read sensitive information from memory.

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' or check the system label/sticker to confirm the model is Dell Precision 7920 or Dell 7920 XlAffected if Model is not Precision 7920 or 7920 Xl, then not affected by this specific CVE
-
Retrieve the current BIOS firmware versionRun 'dmidecode -s bios-version' to display the installed BIOS versionAffected if Command fails or returns no version information - verification may require checking via Dell BIOS setup or Dell SupportAssist
-
Compare the installed BIOS version against the vulnerable rangeCheck if the BIOS version is less than 2.22.1 (for example, 2.21.0, 2.20.3, etc.)Affected if Version is below 2.22.1 - system is running a vulnerable BIOS version
-
Confirm BIOS version format matches Dell versioningVerify the version number format matches Dell's standard (for example, 2.22.1, 2.21.0, 1.5.2)Affected if Version shows as 2.22.1 or higher, then not affected by this vulnerability
A user is affected if the system is a Dell Precision 7920 or Dell 7920 Xl running BIOS firmware version earlier than 2.22.1.

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 · scoped2.22.1
Update the Dell Precision Rack 14G Intel BIOS to version 2.22.2 or later to remediate this vulnerability.
BIOS firmware version 2.22.2 or later
- 1. Navigate to Dell's support website (www.dell.com) and search for your specific model (Precision 7920 or 7920 XL)
- 2. Locate the BIOS/firmware downloads section for your system
- 3. Download the BIOS update version 2.22.2 or later
- 4. Review the update instructions provided by Dell before applying
- 5. Run the BIOS update utility following Dell's recommended procedure (typically requires system restart)
- 6. Verify the BIOS version has been updated to 2.22.2 or later after the update completes
