CVE-2022-29083
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 · uneditedPrior Dell BIOS versions contain an Improper Authentication vulnerability. An unauthenticated attacker with physical access to the system could potentially exploit this vulnerability by bypassing drive security mechanisms in order to gain access to the system.
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 versions prior to the fix contain an improper authentication vulnerability that allows an unauthenticated attacker with physical access to bypass drive security mechanisms and gain system access.

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 your Dell system modelRun 'wmic csproduct get name' or check the system sticker/BIOS splash screen to confirm the exact model (e.g., Chengming 3980, G3 3579, G5 5587)Affected if The model matches one of the affected products: Chengming 3980/3990/3991, G3 3579/3779, G5 5587/5000/5090
-
Check the installed BIOS firmware versionRun 'wmic bios get smbiosbiosversion' or use Dell SupportAssist/Command Update utility to view the current BIOS versionAffected if The installed version is lower than the threshold: Chengming 3980 < 2.23.0, Chengming 3990/3991 < 1.11.0, G3 3579/3779 < 1.21.0, G5 5587 < 1.21.0, G5 5000 < 1.7.0, G5 5090 < 1.14.0
-
Determine if drive security features are enabledCheck if BitLocker, Dell Data Protection, or hardware-based drive encryption (TPM-based) is enabled on the system via 'manage-bde -status' or BIOS drive security settingsAffected if Drive security/encryption mechanisms are configured on the system, as the vulnerability specifically bypasses these protection mechanisms
You are affected if your Dell system model is in the affected list, the BIOS version is below the specified threshold, and drive security features are enabled, since the attacker with physical access could bypass those security mechanisms.

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 · scoped1.7.01.11.01.14.0
Update Dell BIOS to the latest patched version provided by Dell. Since physical access is required, ensure physical security controls are in place for sensitive systems.
Chengming 3980: >= 2.23.0 | Chengming 3990: >= 1.11.0 | Chengming 3991: >= 1.11.0 | G3 3579: >= 1.21.0 | G3 3779: >= 1.21.0 | G5 5587: >= 1.21.0 | G5 5000: >= 1.7.0 | G5 5090: >= 1.14.0
- Identify your specific Dell system model (Chengming 3980, Chengming 3990, Chengming 3991, G3 3579, G3 3779, G5 5587, G5 5000, or G5 5090)
- Visit www.dell.com/support and enter your system Service Tag or search for your model
- Navigate to the Drivers & Downloads section
- Select the BIOS category and download the latest BIOS update package
- Review the release notes to confirm the update addresses CVE-2022-29083
- Follow Dell's recommended BIOS update procedure - typically running the downloaded .exe or .dup file while the system is plugged into AC power
- Allow the BIOS update to complete without interrupting power; the system may restart multiple times
- After the update completes, verify the BIOS version matches or exceeds the fixed version for your model
