Service interruption via null pointer and array faults
Published Jun 13, 2022 · Updated Aug 3, 2024
Null-pointer and out-of-bounds array flaws in Huawei HarmonyOS 2.0 and EMUI 12.0.0 allow local users to interrupt service. The triggering input, affected kernel-module name, and faulty array operation have not been publicly disclosed by Huawei. Low-privilege local access is required, and successful exploitation interrupts device availability without reported data exposure or modification.
