Overview<\/strong><\/p>\n

In the rapidly evolving landscape of cybersecurity, vulnerabilities in widely used software can pose significant risks. One such vulnerability, identified as CVE-2025-3620, affects Google Chrome, one of the most popular web browsers globally. This high-severity flaw can potentially enable a remote attacker to exploit heap corruption via<\/a> a specially crafted HTML page, which could lead to system compromise or data leakage. Given the widespread use of Google Chrome<\/a>, this vulnerability has broad implications and demands immediate attention.<\/p>\n

Vulnerability Summary<\/strong><\/p>\n

CVE ID: CVE-2025-3620
\nSeverity: High (8.8 CVSS score)
\nAttack Vector: Network
\nPrivileges Required: None
\nUser Interaction: Required
\nImpact: System compromise<\/a>, potential data leakage<\/p>\n

Affected Products<\/strong><\/p>\n

Product | Affected Versions<\/p>\n

Google Chrome<\/a> | Prior to 135.0.7049.95<\/p>\n

How the Exploit Works<\/strong><\/p>\n

The vulnerability stems from a use-after-free condition<\/a> in the USB component of Google Chrome. A use-after-free error occurs when a piece of memory is used after it has been freed, which can lead to program instability or, in the worst case, a potential security vulnerability<\/a>.
\nIn this case, a remote attacker<\/a> can craft a specific HTML page to trigger this vulnerability. If a user visits this page, it could exploit the flaw to cause heap corruption<\/a>. This corruption could then be leveraged to execute arbitrary code in the context of the current user, potentially leading to system<\/a> compromise or data leakage.<\/p>\n

Conceptual Example Code<\/strong><\/p>\n

While the exact payload would depend on the specifics of the target system, the general approach might be something like this:<\/p>\n

\n\n<script>\nvar uaf_object = new USBDevice();\nuaf_object.close(); \/\/ Frees the object\n\/\/ uaf_object is now a Use-After-Free (UAF) object\n\/\/ Force JavaScript engine to reuse the freed memory space\nfor (var i = 0; i < 0x1000; i++) {\nvar arr = new Array(uaf_object);\n}\n\/\/ The malicious code that will be executed when the UAF object is used\narr[0x800] = \"arbitrary code\";\n<\/script>\n<\/body>\n<\/html><\/code><\/pre>\n
In this example, the crafted HTML page creates a new USBDevice object, immediately frees it, and then attempts to use it again. This misuse can lead to heap corruption, which is then exploited to insert and execute arbitrary code<\/a> within the browser’s context.<\/p>\n","protected":false},"excerpt":{"rendered":"
