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
Insufficient control flow management in firmware for some Intel(R) SSD, Intel(R) Optane(TM) SSD and Intel(R) SSD DC Products may allow an unauthenticated user to potentially enable escalation of privilege via physical access.

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

Insufficient control flow management in firmware for certain Intel SSD, Optane SSD, and SSD DC products may allow an unauthenticated user with physical access to potentially escalate privileges.

MitigationApply the latest Intel firmware update for affected SSD products; maintain physical access controls as a compensating measure until patching is possible.

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 Intel Optane SSD model
    Check system hardware inventory or BIOS/UEFI information to list installed Intel SSD models. Look specifically for: Optane DC P4800x, P4801x, P5800x, 905p, 900p, or Optane Memory H20/H10.
    Affected if The system contains any of the listed affected Intel Optane SSD models.
  2. Retrieve current firmware version
    Use Intel SSD Toolbox, Intel Memory and Storage Tool, or vendor-specific firmware utility to read the installed firmware version from the detected Intel Optane SSD.
    Affected if Unable to retrieve firmware version from the SSD.
  3. Compare firmware version against thresholds
    Compare the retrieved firmware version number to the affected version thresholds: P4800x/P4801x < e2010600, P5800x < l0310200, H20 < pgf028k, H10 < tgf061k, 905p/900p < fw600.
    Affected if The installed firmware version is lower (numerically or alphabetically earlier) than the specified threshold for that model.
  4. Verify physical access context
    Determine whether the SSD is in a system or environment where an unauthenticated user could gain physical access (e.g., desktop tower, removable drive bay, unattended server).
    Affected if The SSD is accessible to unauthenticated physical users and the firmware version is below the affected threshold.

A system is affected if it contains any of the listed Intel Optane SSD products with firmware version below the specified threshold and is accessible to unauthenticated physical users.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Apply the latest Intel firmware update for affected SSD products; maintain physical access controls as a compensating measure until patching is possible.

Recommended fix High confidence

Upgrade to firmware version e2010600 or later for P4800x/P4801x; l0310200 or later for P5800x; pgf028k or later for H20; tgf061k or later for H10; fw600 or later for 905p/900p

  1. 1. Identify the specific Intel Optane SSD model in your system using Intel SSD Toolbox, Intel Memory and Storage Tool, or system BIOS information.
  2. 2. Download the latest firmware version from Intel's support website (www.intel.com) for your specific model.
  3. 3. Create a backup of critical data before initiating firmware update as a precaution.
  4. 4. Use Intel SSD Toolbox or Intel Memory and Storage Tool to check current firmware version and confirm it is below the fixed version.
  5. 5. Run the firmware update utility and allow the update process to complete without interrupting power.
  6. 6. Verify the firmware has been updated to the fixed version after reboot.
Caveat Firmware updates carry inherent risk; ensure stable power during update to avoid rendering the drive inoperable
