AI-suggested

To mitigate CVE-2024-40823, organizations and users should promptly apply the security updates provided by Apple: macOS Monterey 12.7.6, macOS Sonoma 14.6, and macOS Ventura 13.6.8 or later. Beyond patching, restrict local application execution rights to trusted software only, employing application whitelisting and endpoint protection solutions to prevent untrusted code execution. Implement strict user privilege management to minimize the number of users and processes with local access privileges. Employ monitoring and auditing of local access and application behavior to detect anomalous attempts to access sensitive data. For environments with shared or multi-user systems, enforce strict session isolation and data access controls. Regularly review installed applications and remove unnecessary or potentially risky software. Educate users about the risks of running untrusted applications locally. Finally, maintain an up-to-date asset inventory to ensure all macOS devices are identified and patched promptly.

Description

The issue was addressed with improved checks. This issue is fixed in macOS Monterey 12.7.6, macOS Sonoma 14.6, macOS Ventura 13.6.8. An app may be able to access user-sensitive data.
