CVE-2025-24269 is a critical vulnerability identified in Apple macOS that allows an application to cause unexpected system termination due to improper memory handling. This vulnerability falls under CWE-400, which relates to uncontrolled resource consumption, indicating that the flaw could be exploited to exhaust system resources leading to crashes or denial of service conditions. The vulnerability affects unspecified versions of macOS prior to the release of macOS Sequoia 15.4, where Apple addressed the issue by improving memory management. The CVSS v3.1 base score of 9.8 reflects the vulnerability's critical nature, with an attack vector that is network-based (AV:N), requiring no privileges (PR:N) and no user interaction (UI:N). The impact spans confidentiality, integrity, and availability, meaning exploitation could lead to system crashes that disrupt services and potentially expose sensitive data or corrupt system states. Although no known exploits have been reported in the wild, the vulnerability's characteristics suggest it could be weaponized for denial of service attacks or as a vector for further compromise. The lack of detailed affected versions implies that many macOS deployments could be vulnerable if not updated. The vulnerability's root cause is linked to memory handling errors, which could be triggered by a malicious application or remote attacker sending crafted data, causing the system to terminate unexpectedly. This could disrupt business operations, especially in environments relying heavily on macOS for critical functions.

For European organizations, the impact of CVE-2025-24269 could be significant, particularly for sectors dependent on macOS systems such as creative industries, software development, finance, and government agencies. Unexpected system termination can lead to denial of service, interrupting business continuity and potentially causing data loss or corruption. In environments where macOS devices are integrated into critical infrastructure or used for sensitive operations, this vulnerability could be exploited to degrade operational capabilities or as a stepping stone for further attacks. The high CVSS score indicates that exploitation does not require user interaction or privileges, increasing the risk of widespread impact. Additionally, the potential for confidentiality and integrity impacts means that attackers could leverage this vulnerability to access or manipulate sensitive information indirectly. European organizations with remote access to macOS systems or those that allow installation of third-party applications are particularly at risk. The absence of known exploits currently provides a window for proactive mitigation, but the critical severity necessitates urgent attention to prevent future exploitation.

1. Immediate upgrade to macOS Sequoia 15.4 or later, which contains the patch for this vulnerability. 2. Implement strict application whitelisting to prevent untrusted or malicious applications from executing on macOS systems. 3. Employ network segmentation and firewall rules to limit exposure of macOS devices to untrusted networks, reducing the attack surface. 4. Monitor system logs and crash reports for unusual termination events that could indicate exploitation attempts. 5. Enforce least privilege principles on macOS devices to minimize the impact of potential exploitation. 6. Use endpoint detection and response (EDR) solutions capable of detecting anomalous behaviors related to memory exhaustion or application crashes. 7. Educate users about the risks of installing unverified applications and encourage adherence to security policies. 8. Regularly audit macOS devices for compliance with security baselines and patch levels. 9. Coordinate with Apple support channels for any emerging threat intelligence or additional mitigations. 10. Consider deploying intrusion prevention systems (IPS) that can detect and block exploit attempts targeting this vulnerability.
