CVE-2022-32626 is a medium-severity elevation of privilege vulnerability affecting multiple MediaTek SoCs (System on Chips) including MT6761, MT6765, MT6768, MT6779, MT6781, MT6785, MT6789, MT6833, MT6853, MT6855, MT6873, MT6877, MT6879, MT6883, MT6885, MT6889, MT6893, MT6895, MT6983, MT8168, MT8365, MT8766, MT8781, and MT8791. These chips are widely used in Android smartphones running Android versions 11 and 12. The vulnerability arises from an out-of-bounds write in the display component due to an incorrect bounds check. This flaw allows a local attacker with system execution privileges to escalate their privileges further without requiring any user interaction. The vulnerability is classified under CWE-787 (Out-of-bounds Write), which can lead to memory corruption, potentially allowing arbitrary code execution or system compromise. Exploitation requires the attacker to have system-level execution privileges initially, indicating that this is not a remote or initial access vulnerability but rather one that can be leveraged to gain higher privileges once some level of access is already obtained. The CVSS v3.1 score is 6.7 (medium), reflecting the complexity of exploitation (low attack vector, requiring local access and high privileges) but high impact on confidentiality, integrity, and availability. No known exploits in the wild have been reported, and no official patches are linked in the provided data, though MediaTek has assigned a patch ID (ALPS07326239) indicating a patch likely exists or is in development. The vulnerability affects a broad range of MediaTek chipsets commonly found in mid-range to budget Android devices, making it relevant for a large user base.

For European organizations, the impact of CVE-2022-32626 depends largely on the deployment of devices using the affected MediaTek chipsets. Many enterprises and government agencies use Android devices for communication and operational purposes, including smartphones and tablets with MediaTek SoCs. Successful exploitation could allow an attacker who has already gained system-level access on a device to escalate privileges further, potentially leading to full device compromise. This could result in unauthorized access to sensitive corporate or governmental data, manipulation of device functions, or use of the device as a pivot point for lateral movement within networks. The vulnerability does not require user interaction, increasing the risk once initial access is achieved. However, since exploitation requires system execution privileges, the initial compromise vector must be addressed to prevent privilege escalation chains. The widespread use of MediaTek chips in consumer and enterprise devices in Europe means that sectors relying on mobile communications, such as finance, healthcare, and public administration, could be at risk if devices are not patched. Additionally, the vulnerability could be leveraged in targeted attacks against high-value individuals or organizations if combined with other exploits.

1. Immediate deployment of security patches from device manufacturers or MediaTek is critical. Organizations should liaise with device vendors to confirm patch availability and schedule updates. 2. Implement strict mobile device management (MDM) policies that restrict installation of untrusted applications and enforce least privilege principles to minimize the chance of initial system-level access. 3. Monitor devices for signs of privilege escalation or abnormal behavior, such as unexpected system process activity or unauthorized access attempts. 4. Employ endpoint detection and response (EDR) solutions capable of detecting exploitation attempts or memory corruption indicators on Android devices. 5. Educate users and administrators about the risks of sideloading apps or rooting devices, which can increase the likelihood of initial system-level compromise. 6. For high-security environments, consider restricting or isolating devices with affected MediaTek chipsets until patches are applied. 7. Regularly audit device inventories to identify and track devices with vulnerable chipsets and Android versions 11 or 12. 8. Collaborate with vendors to obtain detailed patch deployment timelines and verify patch integrity post-installation.
