CVE-2024-54084
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 · uneditedAPTIOV contains a vulnerability in BIOS where an attacker may cause a Time-of-check Time-of-use (TOCTOU) Race Condition by local means. Successful exploitation of this vulnerability may lead 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 confidenceAPTIOV BIOS contains a Time-of-check Time-of-use (TOCTOU) race condition vulnerability that can be exploited locally. An attacker with local system access can manipulate timing between a security check and the use of that check's result to achieve arbitrary code execution at the BIOS/firmware level, providing complete system compromise.

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 BIOS firmware versionRun 'dmidecode -s bios-version' on Linux or 'wmic bios get version' on Windows to retrieve the installed BIOS version stringAffected if The reported version falls within >= 5.0 and < 5.038
-
Confirm the BIOS vendor is American MegatrendsRun 'dmidecode -s bios-vendor' on Linux or 'wmic bios get manufacturer' on Windows to identify the BIOS vendorAffected if The vendor is American Megatrends (AMI)
-
Verify the BIOS uses Aptio V firmwareRun 'dmidecode -s bios-release-date' and check the firmware name via vendor tools or system information utilities that display the firmware familyAffected if The firmware is identified as Aptio V
-
Cross-reference the full version string with affected rangeCompare the complete BIOS version string (including any build or release numbers) against the vulnerable range >= 5.0, < 5.038Affected if The version string indicates a build or release less than 5.038 but >= 5.0
The system is affected if it runs American Megatrends Aptio V firmware version 5.0 or higher but lower than version 5.038.

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 · scoped5.038
Apply the vendor-supplied BIOS/firmware update for APTIOV to address the TOCTOU race condition. Given this is a BIOS-level vulnerability with arbitrary code execution impact, prioritize patching affected systems promptly as part of a structured firmware update program.
Aptio V 5.038 or later
- Check with your hardware vendor/OEM for the specific BIOS update procedure for your system
- Obtain the Aptio V firmware update version 5.038 or later from your vendor
- Follow the vendor's standard BIOS/UEFI firmware update process (typically via BIOS setup, USB flash, or vendor-specific update utility)
- After update, verify the BIOS version shows 5.038 or later
