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 an attacker may cause an Improper Restriction of Operations within the Bounds of a Memory Buffer by local. Successful exploitation of this vulnerability may lead to privilege escalation and potentially arbitrary code execution, and impact Integrity.

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 buffer overflow vulnerability (CWE-119) that allows a local attacker to exceed memory buffer boundaries. Successful exploitation enables privilege escalation from current privileges to higher system/BIOS levels and potentially arbitrary code execution, with primary impact to system integrity.

MitigationApply vendor-supplied BIOS/firmware updates from American Megatrends or original equipment manufacturer (OEM). Verify update authenticity through cryptographic signature validation before flashing.

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 BIOS vendor and firmware version
    On Linux, run: dmidecode -s bios-version OR cat /sys/class/dmi/id/bios_version. On Windows, run: wmic bios get SMBIOSBIOSVersion OR systeminfo | findstr /C:"BIOS Version"
    Affected if The BIOS vendor is American Megatrends (AMI) and version is 5.0 or higher but below 5.037
  2. Confirm BIOS is Aptio V
    On Linux, run: dmidecode -s bios-vendor OR cat /sys/class/dmi/id/bios_vendor. On Windows, run: wmic bios get Manufacturer
    Affected if The vendor string contains "American Megatrends" or "AMI" indicating Aptio V firmware
  3. Check if local privilege escalation is possible
    Review user privileges and system hardening. The vulnerability requires local attacker access to the system to exploit.
    Affected if User has local access to the system and BIOS version falls within the affected range (>= 5.0, < 5.037)

If the system runs AMI Aptio V BIOS with version 5.0 through 5.036.x, it is vulnerable to privilege escalation via buffer overflow.

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

Apply vendor-supplied BIOS/firmware updates from American Megatrends or original equipment manufacturer (OEM). Verify update authenticity through cryptographic signature validation before flashing.

Recommended fix High confidence

Aptio V version 5.037 or later

  1. 1. Identify the exact system/model number of the hardware running the affected Aptio V BIOS
  2. 2. Download the BIOS firmware update version 5.037 or later from the system manufacturer's support website (not from third-party sources)
  3. 3. Verify the downloaded update file integrity using checksums provided by the manufacturer
  4. 4. Follow the manufacturer's specific instructions to apply the BIOS update - typically via a USB flash drive or from within the BIOS setup utility
  5. 5. Ensure the system has stable power during the update process to prevent BIOS corruption
  6. 6. After the update completes, enter the BIOS setup to verify the installed version is 5.037 or later
  7. 7. Restore any custom BIOS settings that may have been reset to defaults after the update
Caveat BIOS firmware updates carry a risk of system damage if interrupted; ensure stable power and follow manufacturer instructions exactly
