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 some Intel(R) Server board and Intel(R) Server System BIOS firmware 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
How this class of weakness works · CWE-20

The application accepts input without confirming it is well-formed or within expected bounds, so malformed data can push the program into states its author never anticipated. Attackers probe these gaps to trigger crashes, bypass logic, or feed tainted values into more dangerous operations downstream. Remediating it well means validating and normalising every input at the boundary against a strict allow-list — not merely filtering known-bad values.

Recommended fix High confidence

BIOS firmware version 01.04.0022 (M70klp2sb/M70klp4s2uhh), 0022.d02 (M20ntp2sb/M20ntp1ur304), 7.219 (M10jnp2sb), or 02.01.0015 (S2600bpbr/S2600bps/S2600bpsr) depending on model

  1. 1. Identify the exact Intel server board or system model from the affected product list (M70klp2sb, M70klp4s2uhh, M20ntp2sb, M20ntp1ur304, M10jnp2sb, S2600bpbr, S2600bps, or S2600bpsr)
  2. 2. Download the latest BIOS firmware version from the Intel support website for your specific model
  3. 3. Review Intel's firmware update instructions specific to your server board/system
  4. 4. Apply the BIOS firmware update using Intel's recommended update method (typically via Intel System Update Utility, iFlash, or BMC remote update)
  5. 5. Verify the firmware version has been updated to the fixed release: M70klp2sb/M70klp4s2uhh to >=01.04.0022, M20ntp2sb/M20ntp1ur304 to >=0022.d02, M10jnp2sb to >=7.219, S2600bpbr/S2600bps/S2600bpsr to >=02.01.0015
Caveat BIOS firmware updates carry inherent risks; ensure power stability and follow Intel's update procedures precisely to avoid rendering the system non-functional
