CVE-2025-14174 is a vulnerability identified in the ANGLE graphics abstraction layer used by Google Chrome on Mac systems. The issue is an out-of-bounds memory access flaw classified under CWE-119, which occurs when the software accesses memory outside the bounds of allocated buffers. This can lead to memory corruption, allowing attackers to manipulate program behavior, potentially resulting in arbitrary code execution. The vulnerability is triggered remotely by a crafted HTML page that exploits the flaw in ANGLE’s handling of graphics operations. Since Chrome is widely used and ANGLE is integral to rendering graphics, this vulnerability poses a significant risk. The flaw affects Chrome versions prior to 143.0.7499.110 on Mac, and Google has assigned it a high severity rating with a CVSS 3.1 base score of 8.8. The attack vector is network-based (AV:N), requires no privileges (PR:N), but does require user interaction (UI:R), such as visiting a malicious webpage. The scope is unchanged (S:U), but the impact on confidentiality, integrity, and availability is high (C:H/I:H/A:H). No public exploits have been reported yet, but the potential for exploitation is significant given the ease of triggering the vulnerability through web content. The lack of a patch link in the provided data suggests that users should monitor official Google Chrome update channels for the fixed version 143.0.7499.110 or later.

The vulnerability allows remote attackers to perform out-of-bounds memory access, which can lead to arbitrary code execution within the context of the browser process. This compromises the confidentiality of user data by potentially exposing sensitive information, undermines integrity by allowing malicious code injection or manipulation of browser behavior, and affects availability by causing crashes or denial of service. Organizations worldwide that rely on Google Chrome on Mac devices are at risk of targeted attacks, especially through phishing or malicious websites. Exploitation could facilitate broader network compromise if attackers leverage the browser as an entry point. The high CVSS score reflects the severe impact and ease of exploitation, emphasizing the urgency for remediation. Although no known exploits are currently active, the vulnerability’s characteristics make it a prime candidate for future exploitation by threat actors.

Organizations and users should immediately update Google Chrome on Mac systems to version 143.0.7499.110 or later once available. Until the patch is applied, users should exercise caution when browsing untrusted websites and avoid clicking on suspicious links or opening unknown HTML content. Network-level protections such as web filtering and intrusion prevention systems should be configured to block access to known malicious sites. Security teams should monitor browser crash logs and unusual behavior indicative of exploitation attempts. Employing endpoint detection and response (EDR) solutions can help detect anomalous activity related to memory corruption exploits. Additionally, organizations should ensure that their incident response plans include procedures for rapid patch deployment and user awareness training focused on phishing and social engineering vectors that could deliver crafted HTML payloads. Regular vulnerability scanning and asset inventory management will help identify and prioritize affected systems for remediation.
