CVE-2022-32899 is a high-severity vulnerability affecting Apple macOS and related operating systems including iOS and iPadOS. The flaw allows a malicious application to execute arbitrary code with kernel privileges due to improper memory handling. Kernel privileges represent the highest level of access in the operating system, enabling an attacker to bypass security controls, manipulate system processes, and potentially take full control of the affected device. The vulnerability was addressed by Apple through improved memory management techniques in updates including iOS 15.7, iPadOS 15.7, iOS 16, macOS Ventura 13, and watchOS 9. The CVSS v3.1 score of 7.8 reflects a high impact on confidentiality, integrity, and availability, with an attack vector requiring local access but no privileges and only user interaction. Exploitation requires the victim to run a malicious app, which then leverages the memory handling flaw to escalate privileges to kernel level. While no known exploits in the wild have been reported, the potential for privilege escalation makes this vulnerability critical to address, especially in environments where macOS devices are used for sensitive or critical operations.

For European organizations, the impact of CVE-2022-32899 can be significant, particularly for enterprises and government agencies that rely on Apple macOS devices. Successful exploitation could lead to full system compromise, allowing attackers to access sensitive data, install persistent malware, or disrupt operations. The ability to execute code with kernel privileges undermines the security model of macOS, potentially enabling attackers to bypass endpoint security solutions and evade detection. This risk is heightened in sectors such as finance, healthcare, and critical infrastructure, where data confidentiality and system integrity are paramount. Additionally, organizations with bring-your-own-device (BYOD) policies or remote workforces using macOS devices may face increased exposure. The absence of known exploits in the wild suggests limited immediate threat, but the vulnerability's nature means it could be targeted by advanced persistent threat (APT) groups or cybercriminals seeking to gain deep system access.

European organizations should prioritize deploying the security updates released by Apple for macOS Ventura 13, iOS 15.7 and later, and related platforms to remediate this vulnerability. Beyond patching, organizations should implement strict application control policies to limit the installation and execution of untrusted or unsigned applications, reducing the risk of malicious apps exploiting this flaw. Endpoint detection and response (EDR) solutions should be tuned to monitor for unusual privilege escalation behaviors and kernel-level anomalies. User education is critical to prevent the execution of suspicious applications, especially in environments with less controlled device usage. Network segmentation and least privilege principles should be enforced to contain potential compromises. Regular vulnerability assessments and audits of macOS devices can help identify unpatched systems. For high-security environments, consider restricting macOS device usage or enforcing mobile device management (MDM) policies that enforce compliance and update installation.
