CVE-2022-44611
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 adjacent 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 confidenceThis is an improper input validation vulnerability in the BIOS firmware for certain Intel processors. A privileged user with adjacent access (local or network-proximate) could exploit insufficient input validation to escalate their privileges. The vulnerability is in the firmware layer, meaning it persists before the operating system loads.

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 CPU model in your systemRun 'wmic cpu get name' on Windows or 'cat /proc/cpuinfo | grep "model name"' on Linux to retrieve the processor nameAffected if The CPU model matches Intel Celeron J6413, Intel Celeron N6211, Intel Pentium J6425, Intel Pentium N6415, Intel Atom X6211e, Intel Atom X6413e, Intel Atom X6425e, or Intel Atom X6212re
-
Confirm the processor is the embedded or SoC variantCheck the full processor name for the exact suffix (J6413, N6211, J6425, N6415, X6211e, X6413e, X6425e, X6212re) using 'wmic cpu get name' or 'lscpu'Affected if The processor is an embedded variant with the exact model number suffixes listed (J, N, or X prefixes with the specific numbers)
-
Check the current BIOS firmware versionRun 'wmic bios get smbiosbiosversion' on Windows or 'dmidecode -s bios-version' on Linux to retrieve the installed BIOS versionAffected if The system has any BIOS firmware version installed (all versions of the affected processors are vulnerable)
-
Verify if the system allows local or network-adjacent accessAssess whether untrusted users have physical access or whether the system is networked in a way that allows adjacent attackersAffected if The system is accessible to untrusted local users or is on a network segment where proximate attackers could communicate with it
If the installed CPU model matches any of the eight affected Intel Celeron, Pentium, or Atom variants, the system is vulnerable regardless of the BIOS version since all firmware versions are affected.

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 BIOS/firmware update provided by Intel through the system manufacturer (OEM). Verify which processor models are affected, test the firmware update in a controlled environment first, and plan for potential downtime as BIOS updates carry inherent system stability risks.
