Summary

Huawei HarmonyOS from 6.1.0 contains an out-of-bounds read in the peripheral module. The flaw is a buffer access with an incorrect length value (CWE-805), which lets the module read memory outside the intended buffer. A local attacker without privileges can trigger it with low complexity and no user interaction, and the source says successful exploitation may affect service confidentiality.
