CVE-2022-41597

Fingerprint service disruption via malformed file content

Published Oct 14, 2022 · Updated May 14, 2025

Memory-safety flaws in the fingerprint trusted application in HarmonyOS 2.0 and EMUI 11.0.1 and 12.0.0 allow attackers to disrupt fingerprint service. The application mishandles attacker-controlled file content, causing a heap overflow, out-of-bounds read, or null-pointer dereference; Huawei has not disclosed a narrower code locus. Exploitation requires root permission and can make the fingerprint service operate abnormally, with no published evidence of broader compromise.
