CVE-2026-3062 is a vulnerability identified in the Tint component of Google Chrome on Mac platforms, affecting versions prior to 145.0.7632.116. The issue involves both out of bounds read and write operations, classified under CWE-125 (Out-of-bounds Read) and CWE-787 (Out-of-bounds Write). An attacker can exploit this vulnerability by crafting a malicious HTML page that triggers out of bounds memory access when rendered by the browser. This can lead to memory corruption, which may allow arbitrary code execution, data leakage, or browser crashes. The vulnerability is remotely exploitable without requiring any privileges (AV:N/AC:L/PR:N) but requires user interaction (UI:R), such as visiting a malicious website. The scope is unchanged (S:U), meaning the impact is limited to the vulnerable component within the browser process. The CVSS v3.1 base score is 8.8, reflecting high impact on confidentiality, integrity, and availability. Although no known exploits have been reported in the wild yet, the nature of the vulnerability and its ease of exploitation make it a critical concern. The lack of a patch link suggests that the fix is included in Chrome version 145.0.7632.116 and later. This vulnerability highlights the importance of timely updates and cautious browsing behavior on Mac systems running Chrome.

The potential impact of CVE-2026-3062 is significant for organizations globally, especially those relying on Google Chrome on Mac devices. Successful exploitation can lead to arbitrary code execution within the browser context, enabling attackers to bypass security controls, steal sensitive information, manipulate web content, or disrupt service availability. This could result in data breaches, loss of user trust, and operational disruptions. Since Chrome is widely used in enterprise and consumer environments, the vulnerability poses a broad attack surface. The requirement for user interaction means phishing or social engineering could be used to lure victims to malicious sites. The high severity and broad impact on confidentiality, integrity, and availability make this a critical risk for sectors handling sensitive data, including finance, healthcare, government, and technology industries.

To mitigate CVE-2026-3062, organizations should immediately update all affected Google Chrome installations on Mac to version 145.0.7632.116 or later, where the vulnerability is patched. Beyond patching, implement strict web content filtering and block access to untrusted or suspicious websites to reduce exposure to crafted malicious HTML pages. Employ browser security features such as sandboxing, site isolation, and strict content security policies to limit the impact of potential exploitation. Use endpoint protection solutions capable of detecting anomalous browser behavior and memory corruption attempts. Educate users about the risks of clicking unknown links or visiting untrusted sites to minimize user interaction exploitation vectors. Regularly audit and monitor network traffic for signs of exploitation attempts. For high-security environments, consider deploying browser isolation technologies or restricting browser usage to trusted applications only.
