CVE-2022-26006
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 input validation in the BIOS firmware for some Intel(R) Processors 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 · moderate confidenceImproper input validation in BIOS firmware for certain Intel processors allows a privileged local user to potentially escalate privileges. This is a local access vulnerability requiring the attacker to have some level of system access already.
Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

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 CPU modelRun 'wmic cpu get name' or 'systeminfo' on Windows, or 'cat /proc/cpuinfo' on Linux to identify the processor modelAffected if The CPU model matches any of these: Intel Core i5 7640x, Intel Core i7 3820, Intel Core i7 3920xm, Intel Core i7 3930k, Intel Core i7 3940xm, Intel Core i7 3960x, Intel Core i7 3970x, or Intel Core i7 4820k
-
Check BIOS firmware versionRun 'wmic bios get smbiosbiosversion' on Windows, or use 'dmidecode -s bios-version' on Linux, or check via BMC/IPMI if availableAffected if The system has an affected CPU and the BIOS firmware version is any version (all versions of the listed CPU firmware are affected)
-
Verify local access exposureAssess whether the system allows local console access, physical access, or remote KVM/BMC access that could be leveraged by a local userAffected if Local users or processes with elevated privileges exist on the system, as the vulnerability allows privilege escalation from an already-privileged local position
You are affected if your system uses any of the listed Intel Core processor models and has BIOS firmware installed, since all firmware versions for these models contain the vulnerability and it can be exploited by a local privileged user.

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 the vendor-provided BIOS firmware update from Intel for affected processors. Coordinate patch deployment through enterprise management tools and verify successful installation.
