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 resource shutdown or release in firmware for some Intel(R) SSD, Intel(R) SSD DC, Intel(R) Optane(TM) SSD and Intel(R) Optane(TM) SSD DC may allow a privileged 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

This vulnerability exists in the firmware of specific Intel SSD product lines (Intel SSD, Intel SSD DC, Intel Optane SSD, and Intel Optane SSD DC). The issue involves improper resource shutdown or release, which can be exploited by a privileged local user to cause a denial of service condition.

MitigationApply the Intel-provided firmware update for affected SSD models. Organizations should identify all vulnerable Intel SSD hardware in their environment and apply the corresponding firmware patches following Intel's recommended update procedures.

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
    Run 'lspci | grep -i intel' or 'lsblk -o NAME,MODEL,TRAN' to list storage devices. Look for Intel Optane SSD models including P4800x, P4801x, P5800x, H20, H10, 905p, or 900p.
    Affected if Any Intel Optane SSD model from the affected product list is present in the system
  2. Obtain the firmware version of the Intel Optane SSD
    Use 'smartctl -a /dev/sdX' (where X is the drive letter) from the smartmontools package, or use Intel SSD Toolbox if available. The firmware version appears in the 'Firmware Version' or 'Revision' field in the output.
    Affected if The displayed firmware version cannot be read or the drive does not respond to SMART queries
  3. Compare firmware version against affected ranges for Intel Optane SSD DC P4800x/P4801x
    For P4800x or P4801x models, check if the firmware version is earlier than e2010600. Versions below e2010600 are vulnerable.
    Affected if Firmware version starts with 'e' and the numeric portion is less than 2010600 (e.g., e2010500, e2010400)
  4. Compare firmware version against affected ranges for Intel Optane SSD P5800x
    For P5800x model, check if the firmware version is earlier than l0310200. Versions below l0310200 are vulnerable.
    Affected if Firmware version starts with 'l' and the numeric portion is less than 0310200 (e.g., l0310100)
  5. Compare firmware version against affected ranges for Intel Optane Memory H20/H10
    For H20, check version < pgf028k. For H10, check version < tgf061k. Compare alphanumeric version strings lexicographically.
    Affected if H20 firmware version is earlier than pgf028k, or H10 firmware version is earlier than tgf061k
  6. Compare firmware version against affected ranges for Intel Optane SSD 905p/900p
    For 905p or 900p models, check if firmware version is earlier than fw600. Versions below fw600 are vulnerable.
    Affected if Firmware version is 'fw' followed by a number less than 600 (e.g., fw500, fw400)

The system is affected if any Intel Optane SSD from the listed models is present and its current firmware version is lower than the specified minimum version for that model.

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

Apply the Intel-provided firmware update for affected SSD models. Organizations should identify all vulnerable Intel SSD hardware in their environment and apply the corresponding firmware patches following Intel's recommended update procedures.

Recommended fix Moderate confidence

e2010600 for P4800x/P4801x; l0310200 for P5800x; pgf028k for H20; tgf061k for H10; fw600 for 905p/900p

  1. Identify the specific Intel Optane SSD model in your system using manufacturer tools or system information
  2. Download the latest firmware for your specific model from Intel's support website (support.intel.com) or Solidigm's support website
  3. Backup any critical data before proceeding with firmware update
  4. Use Intel's SSD Firmware Update Tool or the appropriate vendor tool to apply the firmware update
  5. Verify the firmware has been successfully updated to the fixed version
Caveat Firmware updates carry risk of data loss if interrupted; ensure stable power and complete backup before proceeding
