CVE-2022-34741

NFC card-operation interruption via buffer overflow

Published Jul 11, 2022 · Updated Aug 3, 2024

Buffer overflow in Huawei HarmonyOS, EMUI, and Magic UI allows physically proximate attackers to disrupt NFC card operations. Huawei identifies the NFC module as the overflow locus but does not disclose the affected routine, input, or unchecked memory operation. Exploitation requires NFC proximity and can cause exceptions during card registration, deletion, or activation, with no published broader impact.
