CVE-2022-46569Public exploitNetwork attack vector

Memory corruption via oversized wireless key

Published Dec 23, 2022 · Updated Apr 15, 2025

Stack overflow in D-Link DIR-882 1.30B06 and DIR-878 1.30B08 allows remote authenticated users to corrupt memory through a crafted wireless key. An oversized Key parameter exceeds the SetWLanRadioSecurity module's stack-backed storage and overwrites adjacent memory. Administrative access to the network management interface is required; public sources do not establish code execution or a specific service failure.
