CVE-2021-33076
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 · uneditedImproper authentication in firmware for some 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 confidenceImproper authentication exists in the firmware of Intel SSD DC products, allowing an unauthenticated user with physical access to potentially escalate privileges. The vulnerability stems from missing or insufficient authentication checks in the firmware, enabling a physically proximate attacker to bypass security controls.

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 checksWork through these to decide whether this CVE applies to you.
-
Identify Intel SSD model in the systemUse system utilities such as 'lspci', 'lsblk', 'smartctl -i /dev/sda', or vendor-specific tools like Intel SSD Toolbox to list installed storage devices and their model namesAffected if The system contains any of these models: Intel SSD 600p, 660p, 665p, 670p, 700p, 760p, D3 S4510 M.2, or DC P4510 SFF
-
Retrieve the current firmware versionRun 'smartctl -a /dev/sda' (or appropriate device) and look for the 'Firmware Version' field, or use Intel SSD Toolbox to query the drive firmware versionAffected if A firmware version is displayed for one of the affected SSD models listed above
-
Compare firmware version against CVE thresholdsCompare your installed firmware version to the affected thresholds: 600p < 122c, 660p < 005c, 665p < 002c, 670p < 003c, 700p < 005c, 760p < 006c, D3 S4510 < xc311132, DC P4510 < vdv10184Affected if The installed firmware version is lower than the specified threshold for your specific SSD model
-
Verify physical access exposureAssess whether the server or storage system housing the SSD is in a location accessible to unauthorized physical attackers (e.g., shared data centers, unlocked racks, public access areas)Affected if The system is physically accessible to unauthenticated users
You are affected if your system contains an Intel SSD from the listed models and the installed firmware version is below the threshold, combined with potential physical access by untrusted individuals.

Apply the Intel firmware update for affected SSD DC products as specified in Intel's security advisory. Organizations should also restrict physical access to servers and storage systems containing vulnerable drives.
Firmware version 122c or higher for 600p; 005c or higher for 660p; 002c or higher for 665p; 003c or higher for 670p; 005c or higher for 700p; 006c or higher for 760p; xc311132 or higher for D3 S4510 M.2; vdv10184 or higher for DC P4510 SFF
- Identify the specific Intel SSD model (600p, 660p, 665p, 670p, 700p, 760p, D3 S4510 M.2, or DC P4510 SFF) in your environment
- Download the latest firmware for your SSD model from Solidigm's support website (support.solidigm.com) or Intel's legacy support resources
- Create a backup of critical data as a precautionary measure before firmware update
- Use the appropriate Solidigm or Intel firmware update utility (such as Solidigm Storage Tool or Intel SSD Toolbox) to apply the firmware update
- Follow the vendor's complete firmware update procedure, which typically requires a system reboot
- Verify the firmware version after update matches or exceeds: 600p: 122c, 660p: 005c, 665p: 002c, 670p: 003c, 700p: 005c, 760p: 006c, D3 S4510 M.2: xc311132, DC P4510 SFF: vdv10184
