CVE-2025-22832
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 an Out-of-bounds Write by local. Successful exploitation of this vulnerability may lead to data corruption and loss of 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 confidenceAPTIOV BIOS contains an out-of-bounds write vulnerability that can be exploited locally by an attacker to cause memory corruption, potentially leading to data corruption and loss of system availability.

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.
-
Retrieve BIOS firmware versionOn Linux, run 'sudo dmidecode -s bios-version'. On Windows, run 'wmic bios get smbiosbiosversion' or check System Information (msinfo32).Affected if The command returns a version number that cannot be obtained or verified.
-
Verify vendor is AMI Aptio VRun 'sudo dmidecode -s bios-vendor' (Linux) or check BIOS vendor information via msinfo32 (Windows). Confirm the vendor is American Megatrends and the BIOS uses Aptio V architecture.Affected if The vendor is not American Megatrends or the BIOS is not Aptio V.
-
Compare version against affected rangeExamine the returned BIOS version number. The vulnerable range is version 5.0 or higher, but lower than 5.041. Parse the major and minor version components to determine if your version falls in this range.Affected if The BIOS version is 5.0.x, 5.01.x, 5.02.x, 5.03.x, 5.04.x, or any 5.0xx through 5.040xx (i.e., 5.0 <= version < 5.041).
Your system is affected if it runs American Megatrends Aptio V BIOS firmware with a version between 5.0 and 5.040 inclusive.
Generated from the published advisory. Verify against your own configuration.
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 · scoped5.041
Apply the vendor-supplied BIOS firmware update to patch the vulnerability; due to the critical nature of BIOS modifications, ensure proper rollback procedures and post-update testing to verify system stability.
Aptio V version 5.041 or later
- Identify all systems running Aptio V firmware versions 5.0 through 5.040
- Contact AMI (American Megatrends) or your system OEM for the 5.041 (or later) BIOS/firmware update
- Obtain the signed BIOS image from a trusted source (OEM or AMI directly)
- Follow your organization's standard BIOS/firmware update procedure, which typically involves:
- a. Download the firmware update package from the OEM or AMI portal
- b. Verify the digital signature of the update package
- c. Run the firmware update utility or place the update on a USB drive
- d. Reboot the system and enter BIOS/UEFI setup
