CVE-2022-32944 is a high-severity memory corruption vulnerability affecting Apple macOS and other Apple operating systems including tvOS, iOS, iPadOS, and watchOS. The flaw arises from improper state management in kernel-level code, which could allow a malicious application to execute arbitrary code with kernel privileges. This means an attacker could potentially gain full control over the affected device's operating system kernel, leading to complete compromise of confidentiality, integrity, and availability. The vulnerability is classified under CWE-787 (Out-of-bounds Write), indicating that the issue stems from writing data outside the bounds of allocated memory, which can corrupt memory and lead to code execution. Exploitation requires local access (attack vector: local), no privileges are required initially (PR:N), but user interaction is necessary (UI:R), such as running a malicious app. The vulnerability affects multiple Apple OS versions prior to the patched releases: macOS Ventura 13, Monterey 12.6.1, Big Sur 11.7.1, and corresponding versions of iOS, iPadOS, tvOS, and watchOS. Apple addressed the issue by improving state management to prevent memory corruption. Although no known exploits are currently reported in the wild, the high CVSS score of 7.8 reflects the significant risk posed by this vulnerability due to its potential for privilege escalation to kernel level. This vulnerability is particularly critical because kernel-level code execution can bypass most security controls, enabling attackers to install persistent malware, access sensitive data, or disrupt system operations.

For European organizations, this vulnerability poses a serious risk especially for those relying on Apple hardware and software in their IT environments. Organizations using macOS devices for development, administration, or general business operations could face risks of unauthorized access, data breaches, or system disruptions if exploited. The ability to execute code with kernel privileges means attackers could bypass endpoint security solutions, escalate privileges, and move laterally within networks. This could lead to exposure of sensitive corporate data, intellectual property theft, or disruption of critical services. Additionally, organizations in sectors with strict data protection regulations such as GDPR must be vigilant, as exploitation could lead to compliance violations and significant financial penalties. The requirement for user interaction reduces the risk of remote exploitation but does not eliminate it, as social engineering or phishing could trick users into running malicious apps. The lack of known exploits in the wild currently provides some window for patching and mitigation, but the high severity demands prompt action.

European organizations should prioritize updating all Apple devices to the patched OS versions: macOS Ventura 13, Monterey 12.6.1, Big Sur 11.7.1, and the corresponding iOS, iPadOS, tvOS, and watchOS versions. Beyond patching, organizations should implement strict application control policies to prevent installation or execution of unauthorized or untrusted applications, reducing the risk of user-initiated exploitation. Endpoint detection and response (EDR) solutions should be tuned to detect anomalous kernel-level activity or privilege escalation attempts. User awareness training should emphasize the risks of running untrusted apps and the importance of applying OS updates promptly. Network segmentation can limit lateral movement if a device is compromised. For managed Apple environments, leveraging Mobile Device Management (MDM) solutions to enforce update compliance and restrict app installations is recommended. Regular vulnerability assessments and penetration testing focusing on Apple devices can help identify residual risks. Finally, organizations should monitor threat intelligence feeds for any emerging exploits targeting this vulnerability to adapt defenses accordingly.
