CVE-2022-32614 is a vulnerability identified in several MediaTek system-on-chip (SoC) models, specifically MT6789, MT6855, MT6879, MT6893, MT6983, MT8168, MT8365, MT8797, and MT8798, which are widely used in Android 12.0 devices. The vulnerability arises from a logic error in the audio subsystem that leads to possible memory corruption, classified under CWE-415 (Double Free). This memory corruption can be exploited locally to achieve an elevation of privilege, allowing an attacker with existing system execution privileges to escalate their privileges further. Notably, exploitation does not require user interaction, which increases the risk of automated or stealthy attacks. However, the attacker must already have system-level execution privileges, which limits the initial attack vector to scenarios where some level of access is already compromised. The vulnerability impacts confidentiality, integrity, and availability, as indicated by the CVSS vector (C:H/I:H/A:H). The CVSS score of 6.7 categorizes it as a medium severity issue. No known exploits in the wild have been reported to date, and MediaTek has assigned a patch ID (ALPS07310571) for remediation. The vulnerability's root cause is a logic error in the audio component, which could lead to double freeing memory or similar memory corruption issues, potentially allowing privilege escalation to system level. This vulnerability is significant because MediaTek SoCs are prevalent in many Android devices, especially in mid-range smartphones and tablets, which are common in European markets. The lack of user interaction requirement and the potential for full system privilege escalation make this a notable threat if exploited in targeted attacks or malware campaigns.

For European organizations, the impact of CVE-2022-32614 primarily concerns devices running Android 12 on MediaTek SoCs. Many enterprises and government agencies use Android devices for communication, mobile workforce management, and secure access to corporate resources. An attacker exploiting this vulnerability could elevate privileges on compromised devices, potentially gaining control over sensitive data, bypassing security controls, or deploying persistent malware. This could lead to data breaches, espionage, or disruption of mobile services. The vulnerability's requirement for system execution privileges means that initial compromise vectors such as malicious apps or insider threats are prerequisites. However, once exploited, the attacker could gain full control over the device, impacting confidentiality, integrity, and availability of data and services. This is particularly critical for sectors with high security requirements such as finance, healthcare, and government. Additionally, the widespread use of MediaTek chips in consumer devices means that supply chain attacks or targeted campaigns against employees' personal devices could also pose risks to organizational security. The absence of known exploits in the wild reduces immediate risk but does not eliminate the threat, especially as patches may not be uniformly applied across all devices.

1. Immediate deployment of the official patch (ALPS07310571) provided by MediaTek or device manufacturers is essential. Organizations should coordinate with device vendors to ensure timely updates. 2. Implement strict application control policies to prevent installation of untrusted or malicious applications that could gain system execution privileges, thereby reducing the initial attack surface. 3. Employ mobile device management (MDM) solutions to enforce security policies, monitor device integrity, and ensure devices are running updated firmware and OS versions. 4. Conduct regular security audits and vulnerability assessments on mobile devices, focusing on privilege escalation vectors. 5. Educate users about the risks of installing unauthorized apps and the importance of applying updates promptly. 6. For high-security environments, consider restricting the use of devices with vulnerable MediaTek SoCs or Android 12 until patches are confirmed applied. 7. Monitor for unusual device behavior indicative of privilege escalation attempts, such as unexpected system-level processes or unauthorized access to sensitive data. 8. Collaborate with vendors and security communities to stay informed about any emerging exploits or additional patches related to this vulnerability.
