What is CVE-2025-10585?

CVE-2025-10585 is a type confusion vulnerability found in the V8 JavaScript engine of Google Chrome, specifically in versions prior to 140.0.7339.185. This software component is critical for executing JavaScript and rendering HTML content in the browser, a fundamental duty that impacts web browsing capabilities. The flaw stems from how V8 handles object types, causing it to mistakenly interpret an object of one type as another. This mismanagement can potentially lead to heap corruption, allowing a remote attacker to craft a malicious HTML page that, when interacted with, can destabilize the browser or allow for unauthorized access to system resources. Such an exploit can severely disrupt an organization’s web operations, expose sensitive data, or lead to compromised systems.

Potential impact of CVE-2025-10585

Remote Code Execution: The vulnerability can enable attackers to execute arbitrary code on the user's machine through malicious HTML content, which can lead to a full system compromise.
Data Breaches: By exploiting this vulnerability, attackers could potentially access and exfiltrate sensitive information stored within the browser or on the system, jeopardizing organizational confidentiality and compliance.
Service Disruption: An exploit could lead to crashes or severe performance degradation of the browser, affecting organizational productivity by disrupting web-based applications and services critical to business operations.
