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
Improper input validation in firmware for some Intel(R) Optane(TM) SSD products may allow a privileged user to potentially enable escalation of privilege via local 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

Improper input validation in Intel Optane SSD firmware allows a privileged local user to escalate privileges. This is a firmware-level vulnerability in storage devices that could allow a user with existing elevated access to gain additional unauthorized system privileges through malformed input handling.

MitigationApply Intel-provided firmware updates for affected Optane SSD models. Prioritize updates in production environments following standard change management procedures and backup protocols.

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 Intel Optane SSD devices in the system
    On Linux, run 'nvme list' or 'lspci | grep -i optane' to list NVMe devices. On Windows, open Device Manager, expand 'Storage controllers' and look for 'Intel Optane' entries.
    Affected if No Intel Optane SSD devices are found in the system (not affected). If devices are present, continue to next step.
  2. Determine the exact Optane SSD model
    Use 'nvme list' output under the 'Model' column, or on Windows check the device properties in Device Manager. Common model identifiers include 'Intel Optane 900p', '905p', 'P4800x', 'P4801x', or 'H20'.
    Affected if The model is not one of the five affected models (900p, 905p, P4800x, P4801x, H20) - not affected. If it matches one of these, continue.
  3. Retrieve the current firmware version
    On Linux, run 'sudo nvme id-ctrl /dev/nvme0' and look for the 'fwrev' field (replace /dev/nvme0 with the correct device). On Windows, open Intel SSD Toolbox or Intel Memory and Storage Tool CLI and run 'iaatcli list' to see firmware versions.
    Affected if Cannot retrieve firmware version (firmware may not be readable via software tools - contact Intel support for verification). If version retrieved, continue.
  4. Compare firmware version against affected thresholds
    For H20 models: compare firmware version against u4110553-g004. For 900p, 905p, P4800x, P4801x models: compare against e2010650. Versions are text strings - lower versions (alphanumerically earlier) are affected.
    Affected if Installed firmware version is lower than the threshold for your model (H20 < u4110553-g004, or 900p/905p/P4800x/P4801x < e2010650) - you are affected.

You are affected only if you have an Intel Optane SSD model 900p, 905p, P4800x, P4801x, or H20 and your installed firmware version is below the specified threshold for that model.

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

Apply Intel-provided firmware updates for affected Optane SSD models. Prioritize updates in production environments following standard change management procedures and backup protocols.

Recommended fix High confidence

Optane Memory H20: u4110553-g004 | Optane SSD 900p/905p/DC P4800x/DC P4801x: e2010650

  1. Identify the specific Intel Optane SSD model in your environment using Intel SSD Toolbox or system inventory
  2. Download the corresponding firmware update from Intel's support website (www.intel.com)
  3. Review Intel's firmware update instructions and ensure proper power backup is in place
  4. Apply the firmware update using Intel SSD Toolbox or the appropriate Intel firmware update utility
  5. Verify the firmware version has been successfully updated to the fixed release
Caveat Firmware updates require system downtime and proper power backup; incorrect application may result in data loss
