CVE-2022-36326Network attack vector

Service restart via crafted-request memory exhaustion

Published May 18, 2023 · Updated Jan 22, 2025

Uncontrolled resource consumption in affected Western Digital and SanDisk firmware allows remote authenticated users to restart a service via crafted requests. The vendor has not identified the service or request fields; crafted requests consume excessive memory until the service stops and restarts. Root privileges are required, and the documented consequence is a temporary service interruption rather than data disclosure or modification.
