Insufficient Input Validation in Google Chrome Affects Sandbox Security

CVE-2025-6558

What is CVE-2025-6558?

CVE-2025-6558 is a high-severity vulnerability found in Google Chrome, specifically related to insufficient input validation within the ANGLE and GPU components of the browser. This flaw can potentially enable remote attackers to perform a sandbox escape through a specially crafted HTML page, bypassing the protective measures intended to isolate processes and users. The main purpose of the sandbox in web browsers like Chrome is to provide a secure environment that prevents malware from affecting the underlying operating system. If exploited, this vulnerability could allow attackers to execute arbitrary code outside of the sandbox restrictions, significantly compromising the security and integrity of the affected systems.

Potential impact of CVE-2025-6558

1. Sandbox Escape: The primary threat associated with CVE-2025-6558 is the ability to escape the sandbox environment, allowing malicious actors to gain elevated privileges on the host system. This could lead to unauthorized access to sensitive data and applications.

2. Remote Code Execution: Due to the nature of this vulnerability, attackers can execute arbitrary code remotely, which poses risks not only to individual users but also to organizations that rely on affected instances of Chrome for secure browsing. This could result in widespread data breaches.

3. System Compromise: If attackers successfully exploit this vulnerability, they could compromise entire systems, leading to further exploitation opportunities, such as deploying malware or ransomware, which can have catastrophic consequences for organizational operations and reputation.
