CVE-2022-48606Network attack vector

Service interruption via binder NULL pointer dereference

Published Sep 26, 2023 · Updated Sep 24, 2024

NULL pointer dereference in Huawei HarmonyOS and EMUI allows remote attackers to interrupt availability through binder background control. Huawei identifies the locus only as the binder background management and control module and has not disclosed which input or operation produces the null pointer dereference. Network access without authentication or user interaction is sufficient according to NVD; the published impact is limited to availability, but Huawei does not specify whether exploitation causes a hang, crash, or reboot.
