CVE-2019-11137
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 · uneditedInsufficient input validation in system firmware for Intel(R) Xeon(R) Scalable Processors, Intel(R) Xeon(R) Processors D Family, Intel(R) Xeon(R) Processors E5 v4 Family, Intel(R) Xeon(R) Processors E7 v4 Family and Intel(R) Atom(R) processor C Series may allow a privileged user to potentially enable escalation of privilege, denial of service and/or information disclosure 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 · high confidenceInsufficient input validation in system firmware for multiple Intel Xeon processor families and Atom C Series allows a privileged local user to potentially escalate privileges, cause denial of service, or disclose information. The vulnerability stems from improper validation of input data within the firmware layer, which can be exploited through local access to the system.

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 the processor modelRun `lscpu | grep 'Model name'` or `dmidecode -s processor-version` to get the CPU modelAffected if The processor is NOT one of: Xeon Platinum 8253, 8256, 8260, 8276, 8276m, 8276l, 8280l, or 8260l (or not an Intel Xeon/Atom C Series) - if so, this CVE does not apply
-
Determine the BIOS/firmware versionRun `dmidecode -s bios-version` or check via system management interface (IPMI/iLO/iDRAC), or look in BIOS setup under 'Main' or 'BIOS Information'Affected if The firmware version cannot be determined or is older than the patch release date for your system OEM
-
Check if firmware patch has been appliedConsult your system OEM (Dell, HP, Lenovo, etc.) release notes or check Intel SA documentation for your processor family to confirm whether a firmware update addressing this input validation flaw has been installedAffected if The installed firmware predates the Intel patch for CVE-2019-11137 or no patch has been applied
You are affected if you are running an Intel Xeon Platinum 8253/8256/8260/8276/8276m/8276l/8280l/8260l or Atom C Series processor AND your current BIOS/UEFI firmware version does not include the Intel-provided patch for this input validation vulnerability.
Generated from the published advisory. Verify against your own configuration.
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.
From vendor dataApply Intel-provided firmware updates (BIOS/UEFI firmware patches) from system OEMs to remediate the input validation flaw in the affected processor families.
