CVE-2026-7333

Description of the Vulnerability

CVE-2026-7333 is a critical vulnerability in Google Chrome's GPU component, affecting versions prior to 147.0.7727.138. The issue stems from a "use after free" flaw, which allows a remote attacker to bypass the browser’s sandbox protections by leveraging a crafted HTML page. This vulnerability could enable an unauthenticated attacker to execute arbitrary code within the browser process, potentially leading to system compromise. The vulnerability was classified as High severity by Chromium, with a CVSS score of 9.6 (CRITICAL). The vector string indicates that the exploit is non-restricted (AV:N), low complexity (AC:L), and requires user interaction (UI:R). It also grants high privileges (S:C) and allows full exploitation of confidentiality, integrity, and availability (C:H/I:H/A:H).

Sistemas Afectados

The vulnerability impacts Google Chrome versions prior to 147.0.7727.138, including all versions released before April 2026. Users running these versions on Windows, macOS, or Linux systems are at risk if they visit a malicious website or open a compromised HTML document.

Impacto y Explotabilidad

A successful exploitation of CVE-2026-7333 could allow an attacker to escape the browser sandbox, which is a critical security layer designed to isolate processes. This would enable arbitrary code execution, potentially leading to data theft, system control, or further lateral movement. The vulnerability requires user interaction (e.g., visiting a malicious site) but does not need prior authentication. Attackers could craft a web page that triggers the flaw, exploiting it to gain elevated privileges within the browser environment.

Mitigacion y Parches

The recommended mitigation is to update Google Chrome to version 147.0.7727.138 or later, which includes a patch for the vulnerability. Users should also: - Apply security updates from Google regularly. - Avoid visiting untrusted websites or opening suspicious HTML files. - Use browser extensions or sandboxed environments to minimize exposure. For organizations, implementing strict web access policies and monitoring for unusual activity can help reduce the risk of exploitation.
