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
Potential buffer overflow in unsafe UEFI variable handling in Phoenix SecureCore™ for Intel Gemini Lake.This issue affects: SecureCore™ for Intel Gemini Lake: from 4.1.0.1 before 4.1.0.567.

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 · high confidence

A buffer overflow vulnerability exists in Phoenix SecureCore™ UEFI firmware for Intel Gemini Lake platforms due to unsafe handling of UEFI variables. The vulnerability affects versions 4.1.0.1 through 4.1.0.566 and is fixed in version 4.1.0.567. Successful exploitation could allow an attacker to execute arbitrary code in the UEFI pre-boot environment.

MitigationUpdate the system BIOS/UEFI firmware to version 4.1.0.567 or later through the vendor's firmware update process. Verify the update does not conflict with BitLocker TPM or Secure Boot configurations.

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. Check if the system uses Phoenix SecureCore UEFI firmware
    Run 'dmidecode -s bios-vendor' on Linux or 'wmic bios get Manufacturer' on Windows to identify the UEFI firmware vendor. Look for 'Phoenix' or 'Phoenix SecureCore' in the output.
    Affected if The firmware vendor is not Phoenix or the system does not use Phoenix SecureCore.
  2. Verify the platform is Intel Gemini Lake
    Run 'dmidecode -s processor-family' or 'dmidecode -s processor-version' on Linux, or check system information on Windows, to identify the CPU family. Gemini Lake is an Intel low-power platform.
    Affected if The system does not use an Intel Gemini Lake processor.
  3. Retrieve the installed UEFI firmware version
    Run 'dmidecode -s bios-version' on Linux, 'wmic bios get SMBIOSBIOSVersion' on Windows, or access the UEFI/BIOS setup screen to view the firmware version. Note the exact version string.
    Affected if Unable to retrieve a firmware version from the system.
  4. Compare the firmware version against the affected range
    Compare the retrieved version number to the affected range: 4.1.0.1 through 4.1.0.566. Versions 4.1.0.1 <= version < 4.1.0.567 are vulnerable. Versions 4.1.0.567 and later are fixed.
    Affected if The installed version is 4.1.0.1 or higher but lower than 4.1.0.567.

The system is affected if it uses Phoenix SecureCore UEFI firmware on Intel Gemini Lake with version 4.1.0.1 through 4.1.0.566 installed.

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 · scoped
Upgrade available Upgrade to 4.1.0.567 or later
Fixed in 4.1.0.567
Interim mitigation

Update the system BIOS/UEFI firmware to version 4.1.0.567 or later through the vendor's firmware update process. Verify the update does not conflict with BitLocker TPM or Secure Boot configurations.

Recommended fix High confidence

SecureCore for Intel Gemini Lake version 4.1.0.567 or later

  1. Identify the current SecureCore firmware version installed on the affected system
  2. Download the patched SecureCore firmware version 4.1.0.567 or later from the official Phoenix SecureCore vendor website (phoenix.com or phoenixtech.com)
  3. Verify the integrity of the downloaded firmware update package using vendor-provided checksums or digital signatures
  4. Apply the firmware update using the vendor-recommended method (typically via flash utility, BIOS update utility, or firmware update mechanism provided by the system manufacturer)
  5. After applying the update, verify that the firmware has been successfully updated to version 4.1.0.567 or later
  6. Confirm the vulnerability is remediated by verifying the installed firmware version
Caveat Firmware updates carry inherent risks; ensure power stability during update process and follow vendor instructions precisely to avoid rendering the device non-functional
