CVE-2025-43199: 
macOS vulnerability analysis and mitigation

A permissions vulnerability (CVE-2025-43199) was discovered in macOS Core Services that allows a malicious application to gain root privileges. The vulnerability affects multiple versions of macOS including Sequoia 15.6, Sonoma 14.7.7, and Ventura 13.7.7, and was disclosed on July 29, 2025. The issue was identified by security researchers Gergely Kalman and an anonymous researcher (Apple Support, NVD).

The vulnerability stems from a permissions issue in the Core Services component of macOS. The vulnerability has been assigned a CVSS v3.1 base score of 9.8 (CRITICAL) with the vector string CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H, indicating network accessibility, low attack complexity, and no required privileges or user interaction. The vulnerability is classified under CWE-269 (Improper Privilege Management) (NVD).

If exploited, this vulnerability allows a malicious application to elevate its privileges to root level, potentially gaining complete control over the affected system. This level of access would allow an attacker to perform unauthorized actions with the highest system privileges, potentially compromising the entire system security (Apple Support).

Apple has addressed this vulnerability by removing the vulnerable code in the security updates released for macOS Sequoia 15.6, macOS Sonoma 14.7.7, and macOS Ventura 13.7.7. Users are strongly advised to update their systems to these versions to protect against potential exploitation (Apple Support, Apple Support, Apple Support).
