CVE-2025-24119 is a vulnerability identified in Apple macOS that permits an application to execute arbitrary code outside its designated sandbox or with elevated privileges. The root cause is improper state management within the operating system, which fails to enforce strict isolation boundaries between applications and system components. This flaw can be exploited by a local attacker who already has limited privileges on the system to escalate their rights, potentially gaining full control over the affected device. The vulnerability affects multiple macOS versions prior to the patched releases: macOS Sequoia 15.3, macOS Sonoma 14.7.7, and macOS Ventura 13.7.7. The CVSS v3.1 base score is 7.8, reflecting high severity, with an attack vector of local (AV:L), low attack complexity (AC:L), requiring privileges (PR:L), no user interaction (UI:N), unchanged scope (S:U), and high impact on confidentiality, integrity, and availability (C:H/I:H/A:H). The weakness is categorized under CWE-269, which relates to improper privilege management. Although no exploits have been reported in the wild yet, the potential for privilege escalation makes this a critical issue for macOS users. The vulnerability was addressed by Apple through improved state management mechanisms that reinforce sandbox boundaries and privilege restrictions. Organizations using affected macOS versions should prioritize updating to the fixed releases to prevent exploitation.

The impact of CVE-2025-24119 is significant for organizations worldwide that deploy Apple macOS systems. Successful exploitation allows an attacker with limited local access to bypass sandbox restrictions and elevate privileges, potentially gaining full control over the system. This can lead to unauthorized access to sensitive data, manipulation or destruction of critical files, installation of persistent malware, and disruption of system availability. The compromise of macOS endpoints in corporate, government, or critical infrastructure environments could facilitate lateral movement, data exfiltration, and broader network compromise. Since the vulnerability affects core OS security mechanisms, it undermines the trust model of application isolation and privilege separation. Organizations relying on macOS for secure operations, especially those handling sensitive or regulated data, face increased risk of severe breaches if patches are not applied promptly.

To mitigate CVE-2025-24119, organizations should immediately deploy the security updates provided by Apple in macOS Sequoia 15.3, Sonoma 14.7.7, and Ventura 13.7.7 or later. Beyond patching, organizations should enforce the principle of least privilege by limiting user and application permissions to the minimum necessary. Implement strict endpoint security controls, including application whitelisting and behavior monitoring, to detect anomalous privilege escalations or sandbox escapes. Regularly audit local user accounts to prevent unauthorized access and disable unnecessary local accounts. Employ network segmentation to contain compromised devices and reduce lateral movement. Additionally, maintain comprehensive logging and alerting to identify potential exploitation attempts. Educate users about the risks of running untrusted applications, even locally, as exploitation requires local access. Finally, integrate macOS-specific threat detection tools that can identify privilege escalation techniques.
