Local service interruption via privileged process termination

Published Mar 11, 2026 · Updated Mar 11, 2026

Improper privilege management in Lenovo PC Manager before 5.1.160.12302 allows local users to terminate privileged processes. Lenovo has not published the affected component or the operation that permits an unprivileged process to terminate a privileged one. Local authenticated access with low privileges is required, and successful exploitation interrupts the targeted privileged process without reported data disclosure or modification.
