CVE-2022-32924 is a high-severity vulnerability affecting Apple macOS and related operating systems including tvOS, watchOS, iOS, and iPadOS. The vulnerability arises from improper memory handling that 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 user-level security controls, manipulate system processes, access sensitive data, and potentially install persistent malware. The vulnerability is classified under CWE-94, which relates to improper control of code generation, indicating that the flaw involves unsafe handling of code that can be injected or executed. Exploitation requires local access (AV:L) with low attack complexity (AC:L), no privileges required (PR:N), but user interaction is necessary (UI:R), such as running a malicious app. The vulnerability impacts confidentiality, integrity, and availability (all rated high), making it a critical risk if exploited. Apple addressed this issue by improving memory handling in updates released for macOS Big Sur 11.7, macOS Monterey 12.6, macOS Ventura 13, tvOS 16.1, watchOS 9.1, iOS 16.1, and iPadOS 16. Users and organizations running vulnerable versions are urged to apply these patches promptly. No known exploits in the wild have been reported to date, but the potential for severe damage remains significant given the nature of kernel-level code execution.

For European organizations, this vulnerability poses a substantial risk, especially for those relying on Apple hardware and software ecosystems. Organizations in sectors such as finance, healthcare, government, and critical infrastructure that use macOS or Apple mobile devices could face data breaches, system compromise, and operational disruption if exploited. The ability to execute arbitrary code with kernel privileges could allow attackers to install rootkits, steal sensitive information, or disrupt services. Given the high integration of Apple devices in corporate environments and the increasing use of macOS in professional settings, the impact could extend to intellectual property theft, regulatory non-compliance (e.g., GDPR violations due to data exposure), and reputational damage. The requirement for user interaction means phishing or social engineering could be vectors for exploitation, emphasizing the need for user awareness. Although no active exploits are currently known, the vulnerability’s severity and ease of exploitation make it a critical concern for European organizations to address swiftly.

Beyond applying the official Apple patches for all affected operating systems, European organizations should implement several targeted mitigations: 1) Enforce strict application whitelisting policies to prevent unauthorized or untrusted apps from executing, reducing the risk of malicious app installation. 2) Employ endpoint detection and response (EDR) solutions capable of monitoring for unusual kernel-level activity or privilege escalation attempts on macOS devices. 3) Conduct regular user training focused on recognizing and avoiding phishing and social engineering attacks that could lead to execution of malicious apps. 4) Utilize mobile device management (MDM) solutions to enforce security policies, control app installations, and ensure devices remain updated. 5) Implement network segmentation to limit the lateral movement potential of compromised devices. 6) Monitor system logs and kernel event traces for anomalies indicative of exploitation attempts. 7) Establish rapid patch management processes to ensure timely deployment of security updates across all Apple devices in the organization.
