Logic Issue in macOS Affecting Gatekeeper Functionality

CVE-2025-43296

What is CVE-2025-43296?

CVE-2025-43296 is a vulnerability found in macOS, particularly affecting the Gatekeeper functionality, a critical security feature that ensures that only trusted software is installed on the system. This vulnerability arises from a logic issue that could allow applications to bypass the security checks enforced by Gatekeeper. By circumventing these checks, an application may execute potentially harmful code, compromising the integrity of the operating system and putting organizational data and user privacy at risk. The flaw has been identified and addressed in macOS Tahoe 26, emphasizing the importance of keeping systems updated to prevent exploitation.

Potential impact of CVE-2025-43296

1. Bypassing Security Measures: The most significant impact of this vulnerability is the ability for malicious applications to evade Gatekeeper's security checks. This could lead to the installation and execution of untrusted software, thereby increasing the risk of malware infection.

2. Increased Risk of Data Breaches: If attackers can install applications that bypass the Gatekeeper protection, there is a heightened possibility of unauthorized access to sensitive data stored on the device. This could result in severe data breaches, which can have legal and financial repercussions for organizations.

3. System Integrity Compromise: The ability to execute malicious software can lead to a complete compromise of the macOS environment. Attackers may gain control over affected systems, enabling them to manipulate or steal information, deploy ransomware, or use the compromised system as part of a broader attack campaign.
