CVE-2025-43334

Vulnerability

Overview

CVE-2025-43334 is a logic issue in macOS that arises from insufficient entitlement checks. The flaw resides in how the operating system validates whether applications have the necessary permissions to access sensitive user data. This issue was addressed by adding improved entitlement checks in the affected software components.

Exploitation

The vulnerability can be exploited by an app running on the system without requiring any special authentication or network access. An attacker would need for an attacker to first install a malicious application on the target Mac. The precise attack vector and prerequisites are not detailed, but the advisory indicates that any app could potentially exploit this weakness to bypass entitlement-based access controls.

Impact

An attacker who successfully exploits this vulnerability could gain unauthorized access to user-sensitive data. The official description states "An app may be able to access user-sensitive data" and the same phrasing is used in each security advisory [1][2][3]. The impact is classified as Medium severity with a CVSS v3 score of 5.5, suggesting that the potential for data leakage exists but may be limited in limited ways or require specific conditions.

Mitigation

Apple has released patches for macOS Sequoia 15.7.2, macOS Sonoma 14.8.2, and macOS Tahoe 26.1, all published on November 3, 2025 [1][2][3]. Users are encouraged to update to these versions or later to mitigate the risk. No workarounds were described by Apple.
