CVE-2022-41601 is a security vulnerability identified in Huawei's HarmonyOS version 2.0, specifically within the fingerprint trusted application (TA). The vulnerability encompasses a heap overflow, out-of-bounds read, and null pointer dereference issues. These types of memory corruption vulnerabilities can lead to unpredictable behavior, including crashes or potential escalation of privileges within the fingerprint service. The fingerprint TA is a critical component responsible for biometric authentication, and any compromise here could undermine the integrity and availability of the fingerprint authentication mechanism. The vulnerability requires local access with high privileges (PR:H), does not require user interaction (UI:N), and has a low attack vector (AV:L), meaning exploitation is possible only with local access to the device. The CVSS score is 3.4 (low severity), indicating limited impact on confidentiality but some impact on integrity and availability. No known exploits are reported in the wild, and no patches have been linked yet. The vulnerability is categorized under CWE-125 (Out-of-bounds Read), which often leads to memory corruption issues. Overall, while the vulnerability is not trivial, exploitation requires significant access and privileges, limiting its immediate threat scope.

For European organizations, the impact of CVE-2022-41601 is relatively contained due to the low severity and the requirement for high privilege local access. However, organizations using Huawei HarmonyOS devices, especially in sensitive environments where biometric authentication is critical, could face risks of fingerprint service disruption or integrity compromise. This could lead to denial of biometric authentication services or potential bypasses if combined with other vulnerabilities. In sectors like finance, government, or critical infrastructure where biometric authentication is used for secure access, even low-severity vulnerabilities can have operational impacts. Additionally, disruption of fingerprint services could degrade user trust and device usability. Given the lack of known exploits, the immediate risk is low, but the presence of multiple memory corruption issues warrants attention to prevent future exploitation or chaining with other vulnerabilities.

European organizations should implement the following specific mitigations: 1) Inventory and identify all Huawei HarmonyOS 2.0 devices in use, particularly those used for sensitive authentication. 2) Restrict local administrative access to trusted personnel only, minimizing the risk of privilege misuse required for exploitation. 3) Monitor device logs and fingerprint service stability for anomalies that could indicate exploitation attempts. 4) Engage with Huawei for timely patch releases and apply updates promptly once available. 5) Consider deploying additional authentication factors or fallback mechanisms to reduce reliance solely on fingerprint authentication. 6) Conduct regular security assessments and penetration tests focusing on biometric authentication components to detect potential exploitation paths. 7) Educate users and administrators about the risks of local privilege escalation and enforce strict device usage policies.
