CVE-2024-30416Network attack vector

Service interruption via driver use-after-free

Published Apr 7, 2024 · Updated Aug 2, 2024

Use-after-free in the underlying driver module in Huawei HarmonyOS and EMUI allows remote attackers to interrupt device service. The module accesses memory after its associated object has been freed, but Huawei has not disclosed the object, code path, or input that triggers the invalid access. No privileges or user interaction are required according to CISA-ADP; the published impact is limited to availability, without identifying a crash, hang, reboot, or shutdown.
