CVE-2024-6004

Unauthenticated connection denial via unbounded allocation

Published Aug 16, 2024 · Updated Aug 21, 2025

Denial of service in Lenovo Printers allows remote attackers on a shared network to deny printer connections until reboot. The affected firmware allocates resources without limits or throttling, but Lenovo has not disclosed the triggering request, protocol, or component. No authentication or user interaction is required, but the attacker must reach the printer from the shared network; service returns only after reboot.
