CVE-2023-52369Network attack vector

Service disruption and alteration via NFC stack overflow

Published Feb 18, 2024 · Updated Mar 25, 2025

Stack overflow in the NFC module of Huawei EMUI and HarmonyOS allows remote attackers to disrupt or alter NFC services. The public Huawei bulletins identify only the module and overflow class; no affected function, input field, or unchecked operation is disclosed. Published scoring treats the path as unauthenticated and requiring no user interaction, while Huawei limits the stated consequence to service availability and integrity.
