CVE-2023-41306Network attack vector

Bone voice ID feature outage via mutex race

Published Sep 26, 2023 · Updated Sep 24, 2024

Race condition in Huawei HarmonyOS and EMUI bone voice ID trusted application allows remote attackers to cause feature unavailability via mutex misuse. The trusted application mishandles synchronization of shared resources, allowing concurrent execution to leave bone voice ID unavailable. Exploitation requires network reachability and has a bounded availability impact limited to the bone voice ID feature; no confidentiality or integrity impact is reported.
