CVE-2024-36433
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 · uneditedAn arbitrary memory write vulnerability was discovered in Supermicro X11DPH-T, X11DPH-Tq, and X11DPH-i motherboards with BIOS firmware before 4.4.
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 · high confidenceArbitrary memory write vulnerability in Supermicro X11DPH-T, X11DPH-Tq, and X11DPH-i motherboards with BIOS firmware before version 4.4, allowing an attacker to write to arbitrary memory locations.

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.
-
Confirm motherboard modelRun 'dmidecode -s baseboard-product-name' or visually inspect the motherboard label to identify if the system uses an X11DPH-T, X11DPH-Tq, or X11DPH-i modelAffected if The motherboard is not one of the three affected models (X11DPH-T, X11DPH-Tq, X11DPH-i)
-
Retrieve current BIOS versionExecute 'dmidecode -s bios-version' from the command line, or access the BIOS setup screen on boot, or log into the Supermicro IPMI web interface and view the BIOS information under the Maintenance or BIOS menuAffected if Unable to retrieve the BIOS version from the system
-
Compare version to affected rangeCompare the installed BIOS version number to version 4.4. Note the full version string including any build numbers or suffixes to ensure an accurate comparisonAffected if The installed BIOS version is earlier than version 4.4 (for example, 4.3, 4.2, or earlier)
-
Verify BIOS version is not patchedIf multiple BIOS versions are listed in the IPMI or Supermicro update utility, confirm you are checking the currently active installed version rather than a version available for downloadAffected if The currently running BIOS version is earlier than 4.4
A system is affected if it is a Supermicro X11DPH-T, X11DPH-Tq, or X11DPH-i motherboard with BIOS firmware installed that predates version 4.4

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scopedUpdate BIOS firmware to version 4.4 or later on affected Supermicro motherboards to remediate the vulnerability.
BIOS firmware version 4.4 or later
- Visit www.supermicro.com and navigate to the support/downloads section
- Locate the specific motherboard model (X11DPH-T, X11DPH-Tq, or X11DPH-i) in the product database
- Download the BIOS firmware version 4.4 or later from the BIOS updates section
- Verify the downloaded BIOS file checksum matches the one listed on the download page
- Consult the motherboard's user manual for BIOS update instructions (typically requires entering BIOS Setup or using a flash utility)
- Follow the standard Supermicro BIOS flashing procedure to update the firmware to version 4.4 or later
