CVE-2026-50100

Local privilege escalation via uncontrolled DLL search path

Published Jun 15, 2026 · Updated Jun 15, 2026

Uncontrolled DLL search paths in Ricoh and Konica Minolta printer drivers allow local users to execute code with administrator privileges. Affected drivers load DLLs through an uncontrolled search path, allowing a specially crafted driver to supply attacker-controlled code. A low-privileged user must be able to log in to the Windows host; successful exploitation grants administrator-level code execution.
