CVE-2022-32840 is a high-severity vulnerability affecting Apple macOS and related operating systems including watchOS, iOS, and iPadOS. The vulnerability allows a malicious application to execute arbitrary code with kernel privileges. Kernel privileges represent the highest level of access on the system, enabling an attacker to bypass all security controls, modify system behavior, access sensitive data, and potentially install persistent malware. The vulnerability was addressed by Apple through improved security checks and is fixed in macOS Monterey 12.5, watchOS 8.7, iOS 15.6, and iPadOS 15.6. The CVSS v3.1 score is 7.8, indicating a high severity level. The attack vector is local (AV:L), meaning the attacker must have local access to the device, but no privileges are required (PR:N). User interaction is required (UI:R), so the user must trigger the exploit, for example by running a malicious app. The vulnerability impacts confidentiality, integrity, and availability (all rated high). The CWE-269 classification indicates improper privilege management, where an app can escalate privileges improperly. No known exploits in the wild have been reported so far. This vulnerability is critical because it allows privilege escalation to kernel level, which can lead to full system compromise.

For European organizations, this vulnerability poses a significant risk especially to those using Apple devices in their IT environment. Organizations relying on macOS, iOS, or iPadOS devices for critical business operations could face severe consequences if exploited. An attacker gaining kernel-level access can bypass endpoint security, access confidential corporate data, manipulate system processes, or deploy persistent malware. This could lead to data breaches, intellectual property theft, disruption of business operations, and loss of trust. Sectors such as finance, healthcare, government, and technology companies in Europe that use Apple devices extensively are particularly vulnerable. The requirement for local access and user interaction somewhat limits remote exploitation but insider threats or social engineering attacks could still trigger this vulnerability. Given the widespread use of Apple devices in Europe, especially in countries with high technology adoption, the potential impact is substantial if patches are not applied promptly.

European organizations should prioritize patching affected Apple devices by upgrading to macOS Monterey 12.5, iOS 15.6, iPadOS 15.6, and watchOS 8.7 or later versions. Implement strict application control policies to restrict installation and execution of untrusted or unsigned applications, reducing the risk of malicious apps triggering the exploit. Employ endpoint detection and response (EDR) solutions capable of monitoring for suspicious kernel-level activity. Conduct user awareness training to prevent social engineering attacks that could lead to execution of malicious apps. Limit local access to devices by enforcing strong physical security controls and device lock policies. Regularly audit device compliance and maintain an inventory of Apple devices to ensure timely patch management. Consider network segmentation to isolate critical systems and reduce the attack surface. Finally, monitor security advisories from Apple and threat intelligence sources for any emerging exploit activity related to this vulnerability.
