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 · unedited
APTIOV contains a vulnerability in BIOS where a user may cause “Improper Handling of Insufficient Permissions or Privileges” by local access. Successful exploitation of this vulnerability can lead to escalation of authorization and potentially impact 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 confidence

APTIOV BIOS contains a privilege escalation vulnerability where improper handling of insufficient permissions allows a local attacker to gain elevated privileges. Successful exploitation can compromise system Integrity and Availability by allowing unauthorized modification of BIOS-level settings or code execution at the highest privilege level.

MitigationApply the vendor-supplied BIOS/firmware update from the motherboard or system manufacturer to patch the privilege handling flaw. For systems where immediate patching is not feasible, restrict physical access to the machine and monitor for unauthorized local 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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify installed BIOS firmware version
    Use system information utilities (such as dmidecode on Linux, wmic bios on Windows, or BIOS setup utility) to retrieve the current BIOS/UEFI firmware version installed on the system
    Affected if The installed version cannot be determined or retrieved, making version comparison impossible
  2. Confirm BIOS vendor is Ami Aptio V
    Verify that the BIOS firmware is developed by American Megatrends (AMI) and uses the Aptio V core, typically displayed in system information or BIOS setup screens
    Affected if The system does not use Ami Aptio V firmware (different BIOS vendors or other AMI product lines are not affected by this specific CVE)
  3. Compare version against affected range
    Check if the installed BIOS version falls within the range >= 5.0.00 and < 5.041.00. Extract the full version string and compare numerically to the affected range boundaries
    Affected if The installed version is 5.0.00 or higher but lower than 5.041.00, indicating the system is vulnerable to the privilege escalation flaw

A system is affected if it runs Ami Aptio V firmware version 5.0.00 or higher but lower than 5.041.00, allowing a local attacker with physical access to potentially escalate privileges through improper permission handling in the BIOS.

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.

Upgrade available Upgrade to 5.041 or later
Fixed in 5.041
Interim mitigation

Apply the vendor-supplied BIOS/firmware update from the motherboard or system manufacturer to patch the privilege handling flaw. For systems where immediate patching is not feasible, restrict physical access to the machine and monitor for unauthorized local access.

Recommended fix Moderate confidence

Aptio V 5.041

  1. 1. Identify the current Aptio V BIOS version installed on the affected system
  2. 2. Navigate to AMI's official support portal (go.ami.com) or your hardware vendor's BIOS update download page
  3. 3. Download Aptio V version 5.041 or later (the first fixed release)
  4. 4. Verify the downloaded update matches your specific hardware model and revision
  5. 5. Apply the BIOS/firmware update following your vendor's documented update procedure, typically via: - BIOS flash utility (run from within OS), - Firmware update tool in UEFI shell, or - Physical firmware programming if the system is bricked
  6. 6. After update completion, verify the new BIOS version is 5.041 or higher
Caveat BIOS firmware updates carry inherent risks (power interruption can brick the system); ensure stable power and follow vendor recovery procedures
