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 Initialization in firmware for some Intel(R) Optane(TM) SSD products may allow an authenticated user to potentially enable denial of service 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 initialization in Intel Optane SSD firmware allows an authenticated local user to potentially cause a denial of service condition. The vulnerability stems from the firmware failing to properly initialize certain parameters or states during startup, which can be exploited to render the SSD unavailable.

MitigationApply the latest Intel Optane SSD firmware update from Intel's support website. Verify the firmware version on affected systems and test the update in a controlled environment before broad deployment.

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 model present
    Use system inventory tools (e.g., device manager on Windows, lspci or nvme list on Linux) to enumerate installed SSDs and identify Intel Optane models. Look specifically for: Optane Memory H20, Optane SSD 900p, Optane SSD 905p, Optane SSD DC P4800x, or Optane SSD DC P4801x
    Affected if Any of the affected Intel Optane SSD models (H20, 900p, 905p, P4800x, P4801x) is present in the system
  2. Retrieve current firmware version
    Query the SSD firmware version using Intel SSD Toolbox, Intel Memory and Storage Tool, or command-line tools such as 'nvme id-ctrl /dev/nvme0' on Linux. On Windows, use 'smartctl -a /dev/sda' or the Intel tool. Note the firmware revision field returned
    Affected if Firmware version cannot be retrieved or the device does not report a firmware version
  3. Compare version against vulnerability thresholds
    Compare the installed firmware version to the affected ranges: For Optane H20, any version below u4110553-g004 is affected. For Optane 900p, 905p, DC P4800x, and DC P4801x, any version below e2010650 is affected
    Affected if Installed firmware version is lower than u4110553-g004 (for H20) or lower than e2010650 (for 900p/905p/P4800x/P4801x)

If an Intel Optane SSD from the affected product list is present and its firmware version is below the specified thresholds, the environment is vulnerable to CVE-2023-27306

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

Apply the latest Intel Optane SSD firmware update from Intel's support website. Verify the firmware version on affected systems and test the update in a controlled environment before broad deployment.

Recommended fix High confidence

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

  1. 1. Identify the exact Intel Optane SSD model number on the affected system
  2. 2. Download the latest firmware version from Intel's support website (support.intel.com) for the specific Optane SSD model
  3. 3. Use Intel SSD Toolbox or Intel Memory and Storage Tool to apply the firmware update
  4. 4. Follow the firmware update wizard and ensure uninterrupted power during the update process
  5. 5. Reboot the system after the update completes
  6. 6. Verify the installed firmware version matches the fixed release (u4110553-g004 for H20, or e2010650 for 900p/905p/P4800x/P4801x)
Caveat Firmware updates carry risk of data loss; ensure full backup before proceeding and maintain uninterrupted power during update
