CVE-2025-14174 is a vulnerability identified in the ANGLE graphics engine component used by Google Chrome on Mac platforms. The flaw is characterized by an out of bounds memory access condition, which occurs when processing specially crafted HTML content. This vulnerability allows a remote attacker to cause memory corruption by enticing a user to visit a maliciously crafted webpage. The out of bounds access can lead to undefined behavior including potential arbitrary code execution or denial of service through browser crashes. The vulnerability affects Chrome versions prior to 143.0.7499.110 on Mac, and no patches or exploit code have been publicly released at the time of publication. The attack vector is remote and requires user interaction (visiting a malicious site), but no authentication is needed. ANGLE is a critical component responsible for translating OpenGL ES calls to native graphics APIs, making this vulnerability significant as it can be triggered during normal web browsing activities. The lack of a CVSS score necessitates an assessment based on impact and exploitability factors. Given the high potential for exploitation and impact on system integrity and availability, this vulnerability is considered high severity. Organizations relying on Chrome on Mac devices should prioritize patching and consider additional mitigations such as content filtering and user awareness to reduce risk.

For European organizations, the impact of CVE-2025-14174 could be substantial, particularly for those with significant Mac user bases and reliance on Google Chrome for daily operations. Successful exploitation could lead to arbitrary code execution, allowing attackers to compromise user data, escalate privileges, or deploy malware within corporate networks. This could result in data breaches, intellectual property theft, or disruption of business processes. The vulnerability also poses a risk of denial of service through browser crashes, potentially affecting productivity. Given the remote attack vector and the ease of triggering the flaw via web content, organizations with employees frequently browsing the internet or accessing untrusted websites are at higher risk. The absence of known exploits in the wild provides a window for proactive mitigation, but the high severity rating underscores the urgency. Additionally, sectors such as finance, government, and critical infrastructure in Europe could face heightened risks due to the strategic value of their data and services.

The primary mitigation is to update Google Chrome on all Mac devices to version 143.0.7499.110 or later, which contains the fix for this vulnerability. Organizations should enforce automated update policies to ensure timely patch deployment. In addition, implementing web content filtering solutions to block access to suspicious or untrusted websites can reduce exposure to crafted malicious HTML pages. Employing endpoint protection platforms that monitor for anomalous browser behavior may help detect exploitation attempts. User awareness training should emphasize the risks of visiting unknown or untrusted websites and encourage cautious browsing habits. Network segmentation can limit the lateral movement potential if a device is compromised. For high-security environments, consider restricting the use of Chrome on Mac or deploying alternative browsers with different rendering engines until patches are confirmed. Regular vulnerability scanning and penetration testing can help verify the effectiveness of mitigation controls.
