CVE-2024-56434

Service interruption via device node use-after-free

Published Jan 8, 2025 · Updated Sep 18, 2025

Use-after-free in Huawei HarmonyOS 4.0.0 and 4.2.0 and EMUI 14.0.0 allows local users to interrupt a device service. Huawei identifies the locus only as the device node access module and has not disclosed the freed object, affected routine, or triggering input. Exploitation requires low privileges, user interaction, and high-complexity local conditions; the documented outcome is a service exception, with no reported data access or modification.
