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 may cause Improper Access Control by a local attacker. Successful exploitation of this vulnerability may lead to unexpected SPI flash modifications and BIOS boot kit launches, also impacting the 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 an improper access control vulnerability that allows a local attacker to modify SPI flash content, potentially enabling BIOS boot kit deployment and causing unexpected system availability issues.

MitigationApply vendor-supplied BIOS/firmware updates, enforce least-privilege access controls for local system administration, and implement physical security measures to limit unauthorized local access.

Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

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 the BIOS vendor and firmware type
    Check system BIOS information using tools like dmidecode, BIOS setup utility, or system information utilities (e.g., msinfo32 on Windows, biosdecode or dmidecode on Linux)
    Affected if The system does not use Ami Aptio V BIOS - if a different BIOS vendor/type is used, this CVE does not apply
  2. Determine the installed Ami Aptio V version
    Retrieve the BIOS version from system information tools, BIOS setup, or system-specific utilities (such as dmidecode -s bios-version on Linux, or msinfo32 on Windows)
    Affected if The installed version cannot be determined or the system does not report an Ami Aptio V version number
  3. Compare installed version against affected range
    Verify the installed BIOS version against the vulnerable range: version 5.0 through 5.036.x (any version >= 5.0 but < 5.037)
    Affected if The installed version falls within the vulnerable range (5.0 <= version < 5.037)
  4. Assess local access controls
    Review local user account privileges and system administration access controls to determine if untrusted local users could interact with BIOS/UEFI settings or firmware update mechanisms
    Affected if Local users with elevated privileges or physical access exist without strict access controls, increasing exploitability (though version check is the primary indicator)

The system is affected if it runs Ami Aptio V BIOS with version 5.0 through 5.036.x; otherwise, it is not in the affected range.

Upgrade available Upgrade to 5.037 or later
Fixed in 5.037
Interim mitigation

Apply vendor-supplied BIOS/firmware updates, enforce least-privilege access controls for local system administration, and implement physical security measures to limit unauthorized local access.

Recommended fix Moderate confidence

Aptio V version 5.037 or later

  1. 1. Identify the current BIOS version installed on the affected system by accessing the BIOS setup utility or using system information tools
  2. 2. Download the latest Aptio V BIOS firmware version 5.037 or later from the system manufacturer's official support website
  3. 3. Verify the firmware package integrity using checksums provided by the manufacturer
  4. 4. Create a backup of the current BIOS configuration if the system provides backup/restore capabilities
  5. 5. Follow the manufacturer's recommended BIOS update process, which typically involves running a firmware update utility or flashing via the BIOS setup interface
  6. 6. Ensure uninterrupted power during the firmware update process to prevent corruption
  7. 7. After the update completes, verify the new BIOS version reflects 5.037 or later
  8. 8. Reset BIOS to optimized default settings if necessary and reconfigure any custom settings
Caveat BIOS firmware updates may reset configuration to defaults; reconfigure custom settings after upgrade
