CVE-2022-48517Network attack vector

Service interruption via unauthorized DSoftBus access

Published Jul 6, 2023 · Updated Nov 19, 2024

Unauthorized DSoftBus access in affected Huawei HarmonyOS and EMUI releases allows remote attackers to interrupt service availability. Huawei identifies the DSoftBus module as the locus but has not published the service, request path, or authorization operation that accepts access improperly. Network reachability requires neither authentication nor user interaction; the documented consequence is limited to loss of availability.
