CVE-2026-22917Network attack vector

Authenticated service interruption via unbounded resource allocation

Published Jan 15, 2026 · Updated Jan 15, 2026

Resource exhaustion in SICK AG TDC-X401GL firmware before 1.5.0 allows remote authenticated users to interrupt service. A system endpoint accepts input that drives resource consumption without adequate limits or throttling; SICK AG has not identified the endpoint or input field. Low-privileged network access is required, and the documented consequence is bounded to degraded availability or denial of service.
