AI-suggested
To mitigate CVE-2025-43364, organizations should immediately update all macOS systems to versions Sequoia 15.7, Sonoma 14.8, or Tahoe 26.1 or later, where the vulnerability is fixed. Beyond patching, implement strict application whitelisting and sandboxing policies to limit the execution of untrusted or unnecessary applications. Employ endpoint detection and response (EDR) tools to monitor for anomalous behaviors indicative of sandbox escape attempts, such as unusual inter-process communications or privilege escalations. Educate users about the risks of running untrusted software and the importance of user interaction in exploitation scenarios. Restrict local access to macOS systems by enforcing strong physical security and limiting user permissions to the minimum necessary. Regularly audit and review installed applications and their sandbox permissions to reduce the attack surface. Consider deploying macOS security features like System Integrity Protection (SIP) and Apple’s notarization requirements to further harden the environment. Finally, maintain an incident response plan tailored to macOS environments to quickly address any exploitation attempts.
Description
A race condition was addressed with additional validation. This issue is fixed in macOS Sequoia 15.7, macOS Sonoma 14.8, macOS Tahoe 26.1. An app may be able to break out of its sandbox.
