CVE-2025-22831
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 allows a local attacker to write data beyond allocated memory boundaries. Successful exploitation can corrupt data and cause system unavailability.

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 Windows, run 'wmic bios get SMBIOSBIOSVersion' or open msinfo32. On Linux, run 'dmidecode -s bios-version' or check /sys/class/dmi/id/bios_version. Access UEFI setup during boot as an alternative.Affected if The reported version falls within the range 5.0 to 5.040 or shows as less than 5.041
-
Identify the BIOS vendor and platformCheck if the BIOS is Ami Aptio V by examining the BIOS name, vendor string, or firmware descriptor. On Windows, use 'wmic baseboard get product,manufacturer' or msinfo32. On Linux, check /sys/class/dmi/id/bios_vendor and /sys/class/dmi/id/board_name.Affected if The BIOS is identified as Ami Aptio V
-
Confirm version parsing and comparisonVerify the full version string matches the expected format for Ami Aptio V releases (e.g., 5.x.x). Compare numerically against the affected range: version must be >= 5.0 AND < 5.041 to be considered vulnerable.Affected if Version is >= 5.0 and < 5.041 (e.g., 5.001, 5.02, 5.040)
A system is affected if it runs Ami Aptio V firmware version 5.0 or higher but lower than version 5.041.

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-provided BIOS/firmware update for APTIOV to patch the out-of-bounds write vulnerability. This typically involves flashing updated firmware via vendor tools or enterprise deployment mechanisms.
Aptio V version 5.041 or later
- Obtain the Aptio V firmware version 5.041 or later from your system motherboard vendor (e.g., OEM/ODM that ships with AMI Aptio V BIOS)
- Download the firmware update package from the vendor's support website
- Verify the integrity of the downloaded update package using vendor-provided checksums (if available)
- Apply the BIOS/firmware update using the vendor-recommended method (e.g., BIOS flash utility, firmware update tool, or through vendor management interfaces)
- Reboot the system to ensure the new firmware is loaded and verify the BIOS version reflects 5.041 or later
