CVE-2022-20014 is a vulnerability identified in the vow driver component of multiple MediaTek chipsets, including MT6781, MT6785, MT6833, MT6853, MT6853T, MT6873, MT6877, MT6883, MT6885, MT6889, MT6891, MT6893, MT8183, MT8185, MT8385, MT8788, and MT8789. These chipsets are commonly integrated into Android devices running versions 10.0, 11.0, and 12.0. The vulnerability arises from improper input validation in the vow driver, which can lead to memory corruption (classified under CWE-787: Out-of-bounds Write). This memory corruption can be exploited locally to achieve an elevation of privilege, granting an attacker system-level execution privileges. Notably, exploitation does not require user interaction, but it does require the attacker to have high privileges already (as indicated by the CVSS vector requiring PR:H). The vulnerability's CVSS v3.1 base score is 6.7, placing it in the medium severity category. The flaw allows an attacker with local access to the device to potentially execute arbitrary code at the system level, compromising confidentiality, integrity, and availability of the device. No known exploits have been reported in the wild, and MediaTek has assigned a patch ID (ALPS05857308) to address this issue, although no direct patch links are provided in the information. The vulnerability affects a broad range of MediaTek chipsets widely used in mid-range to high-end Android smartphones and tablets, making it a relevant concern for device manufacturers and end-users relying on these platforms.

For European organizations, the impact of CVE-2022-20014 can be significant, especially for those relying on Android devices powered by affected MediaTek chipsets. The elevation of privilege vulnerability allows an attacker with local access to escalate their privileges to system level, potentially enabling installation of persistent malware, unauthorized access to sensitive data, or disruption of device functionality. This can compromise mobile device security, leading to data breaches or loss of control over corporate mobile endpoints. Organizations with Bring Your Own Device (BYOD) policies or those deploying MediaTek-based Android devices for field operations, mobile workforce, or IoT applications may face increased risk. The lack of required user interaction means that once local access is obtained, exploitation can be automated or performed stealthily. Although no known exploits are currently reported in the wild, the vulnerability's presence in multiple Android versions and chipsets suggests a broad attack surface. This could be exploited by malicious insiders, attackers with physical access, or through other local compromise vectors. The potential impact extends to confidentiality (data exposure), integrity (unauthorized code execution), and availability (device instability or denial of service). Given the widespread use of MediaTek chipsets in consumer and enterprise devices across Europe, the threat is relevant for sectors including finance, healthcare, government, and critical infrastructure where mobile device security is paramount.

To mitigate CVE-2022-20014 effectively, European organizations and device manufacturers should: 1) Ensure timely application of vendor patches: Coordinate with device vendors and MediaTek to obtain and deploy firmware or OS updates containing the ALPS05857308 patch. 2) Enforce strict device access controls: Limit local access to devices through physical security measures and endpoint management solutions to reduce the risk of local exploitation. 3) Implement mobile device management (MDM) policies: Use MDM tools to enforce security configurations, restrict installation of untrusted applications, and monitor for suspicious activity indicative of privilege escalation attempts. 4) Conduct regular security audits and penetration testing: Include tests for local privilege escalation vulnerabilities on devices with MediaTek chipsets. 5) Educate users and administrators: Raise awareness about the risks of local device compromise and the importance of applying updates promptly. 6) Consider device procurement policies: Prefer devices with timely security update support and verified patch deployment processes. 7) Monitor threat intelligence feeds: Stay informed about any emerging exploit developments related to this vulnerability to respond rapidly if exploitation in the wild is detected.
