CVE-2024-33659
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 · uneditedAMI APTIOV contains a vulnerability in BIOS where an attacker may cause an Improper Input Validation by a local attacker. Successful exploitation of these vulnerabilities may lead to overwriting arbitrary memory and execute arbitrary code at SMM level, also impacting Confidentiality, Integrity, and Availability.
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 confidenceAMI APTIOV BIOS contains an improper input validation vulnerability that allows a local attacker to overwrite arbitrary memory and execute arbitrary code at SMM (System Management Mode) level, which operates at the highest privilege level below the operating system.

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 vendor and platformUse system information tools (dmidecode on Linux, msinfo32 on Windows, or the BIOS/UEFI setup utility) to determine the BIOS firmware vendor and platform nameAffected if The system uses AMI Aptio V as the BIOS/firmware platform
-
Retrieve the installed BIOS versionObtain the BIOS version string from system information utilities, manufacturer tools, or the UEFI/BIOS setup screenAffected if The installed BIOS version is AMI Aptio V and falls within the range >= 5.0 and < 5.038
-
Confirm local access to the systemVerify the presence of local attacker access vectors such as physical access, operating system privileges, or ability to interact with system management mode interfacesAffected if A local attacker can potentially trigger the improper input validation to overwrite memory and execute code at SMM level
The system is affected if it runs AMI Aptio V firmware version 5.0 through 5.037, since the vulnerability allows code execution at the highest x86 privilege level (SMM) through improper input validation.

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 from the system OEM. This is a firmware-level fix that requires flashing new BIOS, typically requiring administrative privileges and potentially physical access.
APTIO V firmware version 5.038 or later
- Obtain the fixed APTIO V firmware version 5.038 or later from the motherboard/BIOS vendor
- Verify the firmware binary integrity using vendor-provided checksums before flashing
- Apply the firmware update through the vendor-recommended method (e.g., flash utility, BIOS update tool, or in-band update process)
- After updating, verify the BIOS version reflects 5.038 or higher to confirm successful remediation
- Ensure the system is powered continuously during the update process to prevent firmware corruption
