CVE-2025-24195 is a critical security vulnerability identified in Apple macOS operating systems, caused by an integer overflow due to inadequate input validation. This flaw allows an attacker with no prior privileges and without requiring user interaction to execute a privilege escalation attack, potentially gaining full control over the affected system. The vulnerability affects multiple recent macOS versions, including Ventura 13.7.5, Sequoia 15.4, and Sonoma 14.7.5, where it has been addressed by improved input validation mechanisms. The integer overflow likely occurs in a system component responsible for handling user inputs or system calls, which when exploited, can corrupt memory or bypass security checks. The CVSS v3.1 score of 9.8 reflects the vulnerability’s critical nature, with network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:N), no user interaction (UI:N), and high impact on confidentiality, integrity, and availability (C:H/I:H/A:H). Although no known exploits have been reported in the wild, the vulnerability’s characteristics make it highly exploitable and dangerous. The CWE-276 classification indicates improper privilege management, emphasizing the risk of unauthorized privilege escalation. Organizations running macOS systems should consider this a high-priority security issue and apply patches promptly to prevent potential exploitation.

For European organizations, the impact of CVE-2025-24195 can be severe, especially for those relying on macOS devices for critical operations, development, or sensitive data processing. Successful exploitation could lead to attackers gaining root or system-level privileges, allowing them to install malware, exfiltrate data, disrupt services, or move laterally within networks. This threatens confidentiality, integrity, and availability of organizational assets. Sectors such as finance, government, healthcare, and technology are particularly at risk due to the sensitive nature of their data and operations. Additionally, organizations with remote or hybrid workforces using macOS devices may face increased exposure. The lack of required authentication and user interaction lowers the barrier for attackers, increasing the likelihood of exploitation if systems remain unpatched. The absence of known exploits currently provides a window for proactive defense, but the critical severity demands urgent attention.

1. Immediate deployment of the official patches provided in macOS Ventura 13.7.5, Sequoia 15.4, and Sonoma 14.7.5 to all affected systems. 2. Enforce strict update policies and verify patch installation status across all macOS endpoints. 3. Implement endpoint detection and response (EDR) solutions capable of identifying unusual privilege escalation behaviors or memory corruption attempts. 4. Restrict network exposure of macOS devices where possible, especially limiting access to management interfaces and services that could be leveraged for exploitation. 5. Conduct regular security audits and vulnerability assessments focusing on macOS environments. 6. Educate IT and security teams about this vulnerability to enhance monitoring and incident response readiness. 7. Employ application whitelisting and least privilege principles to minimize the impact of potential compromises. 8. Monitor threat intelligence feeds for emerging exploit techniques related to this CVE to adapt defenses accordingly.
