CVE-2025-65078

Root code execution via untrusted program resolution

Published Feb 3, 2026 · Updated Feb 3, 2026

Untrusted search path handling in Lexmark Embedded Solutions Framework firmware allows local users to execute arbitrary code as root. The esfhelper binary executes a program from an untrusted location instead of restricting resolution to a trusted path. ZDI requires prior low-privileged code execution on the device, while Lexmark assesses an unauthenticated network path to arbitrary code execution.
