CVE-2022-46319Network attack vector

Memory corruption via unchecked calibration boundary

Published Dec 20, 2022 · Updated Apr 16, 2025

Out-of-bounds write in fingerprint calibration in Huawei HarmonyOS 2.0 and EMUI 11.0.1 and 12.0.0 allows attackers to corrupt memory. Huawei describes the calibration path as lacking boundary determination before the write but does not disclose the affected function or input format. Public records do not identify the required access path or bound the consequence beyond an out-of-bounds memory write.
