CVE-2022-32942 is a high-severity vulnerability affecting Apple macOS operating systems, specifically addressed in macOS Monterey 12.6.2, macOS Ventura 13.1, and macOS Big Sur 11.7.2. The vulnerability arises from improper memory handling, classified under CWE-125 (Out-of-bounds Read). This flaw allows a malicious application to execute arbitrary code with kernel privileges, effectively granting the attacker full control over the affected system at the highest privilege level. Exploitation requires local access to the system and some user interaction, as indicated by the CVSS vector (AV:L/AC:L/PR:N/UI:R). The vulnerability impacts confidentiality, integrity, and availability, as kernel-level code execution can lead to data theft, system manipulation, or denial of service. Although no known exploits are currently observed in the wild, the potential for severe damage is significant due to the elevated privileges gained upon successful exploitation. The issue was resolved by Apple through improved memory handling in the kernel, mitigating the risk by preventing out-of-bounds memory access that could be leveraged for arbitrary code execution.

For European organizations, this vulnerability poses a critical risk especially to those relying on macOS systems for sensitive operations, including government agencies, financial institutions, research entities, and technology companies. Successful exploitation could lead to full system compromise, data breaches, intellectual property theft, and disruption of critical services. The ability to execute code with kernel privileges means attackers could bypass most security controls, implant persistent malware, or pivot within networks. Given the high adoption of Apple devices in sectors such as creative industries, education, and certain government branches across Europe, the threat could undermine operational integrity and confidentiality. Additionally, organizations with Bring Your Own Device (BYOD) policies that include macOS devices may face increased exposure. The absence of known exploits in the wild currently reduces immediate risk but does not eliminate the threat, as weaponization could occur rapidly once exploit code becomes available.

European organizations should prioritize immediate patching of all vulnerable macOS systems by upgrading to macOS Monterey 12.6.2, Ventura 13.1, or Big Sur 11.7.2 or later. Beyond patching, organizations should implement strict application whitelisting to prevent untrusted apps from executing, especially those requiring elevated privileges. Employ endpoint detection and response (EDR) solutions capable of monitoring kernel-level activities and anomalous behavior indicative of exploitation attempts. Enforce least privilege principles to limit user ability to install or run unauthorized software. Regularly audit and restrict local user accounts to reduce the attack surface. For environments with BYOD policies, ensure devices comply with security standards and are updated promptly. Network segmentation can limit lateral movement if a device is compromised. Finally, conduct user awareness training emphasizing the risks of running untrusted applications and the importance of applying updates promptly.
