CVE-2025-24151 is a vulnerability identified in Apple macOS that allows a local application to cause unexpected system termination or corrupt kernel memory due to improper memory handling. The issue is classified under CWE-400, which relates to uncontrolled resource consumption or memory management flaws. This vulnerability can be triggered by an app running with user privileges but does not require elevated permissions, making it accessible to any user-level process with user interaction. The flaw can lead to denial of service by crashing the system or causing kernel memory corruption, potentially destabilizing the operating system. The vulnerability affects multiple macOS versions prior to the patched releases: macOS Sequoia 15.3, Sonoma 14.7.3, and Ventura 13.7.3, where Apple has implemented improved memory handling to mitigate the issue. The CVSS v3.1 score of 5.5 reflects a medium severity, with the vector indicating local attack vector (AV:L), low attack complexity (AC:L), no privileges required (PR:N), user interaction required (UI:R), unchanged scope (S:U), no impact on confidentiality or integrity (C:N/I:N), and high impact on availability (A:H). There are currently no known exploits in the wild. This vulnerability primarily threatens system stability and availability rather than data confidentiality or integrity. It is important for organizations and users running affected macOS versions to apply the security updates provided by Apple to prevent potential denial of service conditions caused by malicious or buggy applications.

The primary impact of CVE-2025-24151 is on system availability, as exploitation can cause unexpected system termination or kernel memory corruption leading to crashes or instability. This can disrupt business operations, cause data loss due to abrupt shutdowns, and reduce user productivity. Since the vulnerability does not affect confidentiality or integrity, it does not directly enable data theft or unauthorized modification. However, denial of service conditions on critical macOS endpoints can have cascading effects in enterprise environments, especially where Apple hardware is integral to workflows, such as in creative industries, software development, and government agencies. The requirement for local access and user interaction limits remote exploitation but does not eliminate risk from malicious insiders or social engineering attacks. Organizations with unmanaged or poorly controlled macOS devices are at higher risk. The absence of known exploits in the wild reduces immediate threat but does not preclude future exploitation attempts, especially as attackers often target kernel vulnerabilities for privilege escalation or persistence. Overall, the vulnerability poses a moderate operational risk that should be addressed promptly to maintain system reliability.

To mitigate CVE-2025-24151, organizations and users should immediately update affected macOS systems to the patched versions: macOS Sequoia 15.3, macOS Sonoma 14.7.3, or macOS Ventura 13.7.3. Applying these updates ensures improved memory handling that resolves the vulnerability. Beyond patching, organizations should enforce strict application control policies to limit installation and execution of untrusted or unsigned applications, reducing the risk of malicious apps triggering the flaw. Employ endpoint detection and response (EDR) solutions capable of monitoring for abnormal application behavior or system crashes indicative of exploitation attempts. Educate users about the risks of running unverified software and the importance of user interaction in triggering this vulnerability to reduce inadvertent exploitation. Regularly audit and inventory macOS devices to ensure compliance with patch management policies. For high-security environments, consider restricting local user permissions further and employing macOS security features such as System Integrity Protection (SIP) and notarization enforcement. Monitoring system logs for kernel crashes or unusual terminations can provide early warning signs of attempted exploitation.
