CVE-2026-14038 describes a vulnerability in Google Chrome's New Tab Page where insufficient validation of untrusted input allows a remote attacker with control over the renderer process to potentially perform a sandbox escape using a crafted HTML page. This vulnerability affects versions prior to 150.0.7871.47. The CVSS 3.1 score is 9.3 (AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:N), indicating network attack vector, low attack complexity, no privileges required, user interaction required, scope changed, and high confidentiality and integrity impact with no availability impact. The vulnerability is categorized under CWE-20 (Improper Input Validation). The vendor advisory URL is provided but does not explicitly state patch or remediation details.

Successful exploitation could allow an attacker who has already compromised the renderer process to escape the sandbox, potentially leading to elevated privileges and unauthorized access to system resources. The impact includes high confidentiality and integrity loss but no direct availability impact. This could facilitate further compromise beyond the browser sandbox.
