CVE-2024-54529 is a logic flaw in Apple macOS that permits an application to execute arbitrary code with kernel-level privileges. This vulnerability arises from insufficient validation or improper checks in the kernel code, allowing a local app to escalate privileges beyond its intended scope. The issue is categorized under CWE-94, indicating improper control over code generation or execution, which can lead to remote or local code execution vulnerabilities. The vulnerability affects unspecified versions of macOS prior to the patched releases: macOS Sequoia 15.2, Ventura 13.7.2, and Sonoma 14.7.2. The CVSS v3.1 score is 7.8 (high), reflecting that exploitation requires local access (AV:L), low attack complexity (AC:L), no privileges required (PR:N), but user interaction is necessary (UI:R). The scope remains unchanged (S:U), but the impact on confidentiality, integrity, and availability is high (C:H/I:H/A:H), meaning a successful exploit can fully compromise the system. No public exploits have been reported yet, but the severity and nature of the vulnerability make it a critical concern for macOS users. The flaw was addressed by Apple through improved logic checks in the kernel to prevent arbitrary code execution. Given the kernel-level access gained, attackers could bypass security controls, install persistent malware, or disrupt system operations.

For European organizations, this vulnerability poses a significant risk, especially those relying on macOS devices for critical operations, including government agencies, financial institutions, and technology firms. Exploitation could lead to full system compromise, exposing sensitive data, intellectual property, and user credentials. The ability to execute code with kernel privileges allows attackers to bypass sandboxing and security mechanisms, potentially enabling persistent backdoors or lateral movement within networks. Although exploitation requires local access and user interaction, insider threats or targeted phishing campaigns could leverage this vulnerability. The absence of known exploits in the wild provides a window for proactive patching. However, organizations with mixed OS environments that include macOS endpoints must prioritize vulnerability management to prevent potential escalations. The impact extends to availability as attackers could disrupt or disable critical systems, affecting business continuity.

1. Immediately apply the official Apple security updates: macOS Sequoia 15.2, Ventura 13.7.2, and Sonoma 14.7.2 or later versions. 2. Restrict local application execution privileges by enforcing strict application whitelisting and least privilege principles on macOS endpoints. 3. Implement endpoint detection and response (EDR) solutions capable of monitoring for unusual kernel-level activity or privilege escalations. 4. Educate users to avoid executing untrusted applications and to be cautious with user interactions that could trigger exploitation. 5. Limit physical and remote access to macOS devices to trusted personnel only. 6. Regularly audit and monitor macOS systems for signs of compromise or anomalous behavior. 7. Employ network segmentation to isolate critical macOS systems from broader enterprise networks to reduce lateral movement risk. 8. Maintain up-to-date backups and incident response plans tailored for macOS environments to ensure rapid recovery if exploitation occurs.
