CVE-2022-41598 is a set of vulnerabilities identified in Huawei's HarmonyOS version 2.0, specifically within the fingerprint trusted application (TA). The vulnerabilities include a heap overflow, out-of-bounds read, and null pointer dereference. These issues arise from improper memory handling in the fingerprint TA, which is a critical component responsible for biometric authentication services on HarmonyOS devices. Exploiting these vulnerabilities could lead to denial of service or potentially impact the integrity of the fingerprint service, although there is no indication that confidentiality is compromised. The CVSS 3.1 base score is 3.4, indicating a low severity level. The attack vector is local (AV:L), requiring high privileges (PR:H) but no user interaction (UI:N). The vulnerabilities do not appear to be exploited in the wild at this time, and no patches have been publicly linked. The underlying weaknesses correspond to CWE-476 (null pointer dereference), CWE-125 (out-of-bounds read), and CWE-787 (heap overflow), all of which are common memory safety issues that can cause application crashes or unpredictable behavior. Given the fingerprint TA's role, successful exploitation could disrupt biometric authentication, potentially locking users out or causing service instability. However, the requirement for high privileges and local access limits the attack surface to scenarios where an attacker already has significant control over the device or system.

For European organizations, the impact of CVE-2022-41598 is primarily related to device availability and service reliability rather than data confidentiality or integrity. Organizations using Huawei HarmonyOS devices, particularly version 2.0, may experience disruptions in fingerprint authentication services if this vulnerability is exploited. This could affect user access to devices or secure applications relying on biometric authentication, potentially leading to operational delays or user inconvenience. Since exploitation requires high privileges and local access, the threat is more relevant in scenarios where devices are physically accessible or already compromised by other means. The low CVSS score and absence of known exploits reduce the immediate risk, but organizations should remain vigilant, especially those with Huawei devices integrated into their mobile or IoT infrastructure. Disruption of biometric services could also impact security policies that rely on fingerprint authentication, necessitating fallback mechanisms. Overall, while the direct impact on European organizations is limited, the vulnerability underscores the importance of maintaining device security hygiene and monitoring for updates from Huawei.

To mitigate CVE-2022-41598, European organizations should implement the following specific measures: 1) Inventory and identify all Huawei HarmonyOS devices running version 2.0 within their environment to assess exposure. 2) Monitor Huawei's official security advisories and update channels for patches addressing this vulnerability and apply them promptly once available. 3) Restrict physical access to devices to prevent local attackers from gaining the high privileges required for exploitation. 4) Employ endpoint protection solutions capable of detecting abnormal behavior or crashes related to fingerprint services, which could indicate exploitation attempts. 5) Implement multi-factor authentication alternatives or fallback mechanisms to maintain access control if fingerprint authentication is disrupted. 6) Educate users and administrators about the risks of privilege escalation and local attacks, emphasizing the importance of device security. 7) For critical environments, consider network segmentation and device usage policies to limit exposure of vulnerable devices. These targeted actions go beyond generic advice by focusing on device management, access control, and monitoring specific to the fingerprint TA vulnerability context.
