A critical permission flaw in Apple macOS allows local malicious applications to escalate privileges to root, posing a severe risk of full system compromise.

This is a privilege escalation vulnerability where insufficient restrictions allow a malicious application to bypass standard security controls and execute code with root privileges. The vulnerability requires local access and user interaction to initiate the malicious application.

Successful exploitation of this vulnerability grants an attacker full administrative control over the affected system. This level of access allows for the theft of sensitive data, the installation of persistent malware, and the potential disruption of critical business operations. With a CVSS score of 7.8, the vulnerability is classified as High, reflecting the significant impact of a complete compromise of the underlying operating system.

Immediate Action: Update all Apple macOS installations to version 15.6 or later to apply the necessary security restrictions.

Proactive Monitoring: Review system logs for unusual process execution patterns or unauthorized attempts to perform administrative tasks by non-privileged accounts.

Compensating Controls: Implement strict application control policies to prevent the execution of untrusted or unsigned binaries, which serves as a vital defense against malicious applications.

Public Exploit Available: exploit_available (false).

The risk associated with this vulnerability is significant due to the potential for total system compromise. IT administrators should prioritize the deployment of the macOS 15.6 update across all managed assets to ensure the root privilege escalation path is effectively closed. Continuous monitoring of system integrity remains essential until all endpoints are fully patched.
