CVE-2026-50100
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 · uneditedMultiple printer drivers provided by Ricoh Company, Ltd. and KONICA MINOLTA JAPAN, INC. contain a privilege escalation vulnerability. If this vulnerability is exploited, an attacker who can log in to a computer running an affected printer driver could elevate privileges by using a specially crafted driver.
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 confidenceThis is a privilege escalation vulnerability in printer drivers from Ricoh and KONICA MINOLTA. An attacker who already has local logon access to a system running an affected printer driver can exploit it by deploying a specially crafted malicious driver to elevate their privileges to higher integrity levels.

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 installed printer driversOpen Windows Control Panel > Devices and Printers, or run 'driverquery /v' and look for entries containing 'Ricoh' or 'Konica Minolta' in the driver nameAffected if Ricoh or Konica Minolta printer drivers are listed in installed devices or driver query results
-
Check driver file locationsSearch the system for driver files (.sys, .dll) associated with Ricoh or Konica Minolta; common paths include C:\Windows\System32\DriverStore\FileRepository\ and C:\Windows\System32\drivers\Affected if Driver files from Ricoh or Konica Minolta exist in driver storage directories
-
Verify current user privilegesRun 'whoami /groups' or check System Properties > Computer Name to determine if the current account is a standard user versus an administratorAffected if The account is a standard user (not administrator) and Ricoh/Konica Minolta drivers are present - indicating potential privilege gap exists
-
Audit recent driver installationsOpen Event Viewer > Windows Logs > System and filter for Event ID 219 (driver loading) or check C:\Windows\INF\setupapi.dev.log for recent driver additionsAffected if Ricoh or Konica Minolta drivers were recently loaded or installed on the system
-
Review local user accountsRun 'net user' to list all local accounts, then check if any have been added after the driver installation dateAffected if New local administrator accounts exist that were not authorized, suggesting post-exploitation activity
A system is affected if it runs Ricoh or Konica Minolta printer drivers and a standard user account can be leveraged to gain SYSTEM/administrator privileges through the driver vulnerability.
