This vulnerability resides in versions prior to 147.0.7727.101. A remote attacker could exploit this flaw by crafting a malicious HTML page designed to trigger the type confusion, leading to an out-of-bounds memory access. The Chromium security team rated this vulnerability as having medium severity. Successful exploitation could allow an attacker to potentially execute arbitrary code within the context of the browser. Defenders should prioritize patching vulnerable Chrome installations.\u003c/p\u003e\n\u003ch2 id=\"attack-chain\"\u003eAttack Chain\u003c/h2\u003e\n\u003col\u003e\n\u003cli\u003eThe attacker crafts a malicious HTML page containing JavaScript code designed to trigger the type confusion vulnerability in the V8 engine.\u003c/li\u003e\n\u003cli\u003eThe victim visits the malicious HTML page, either by directly navigating to it or by being redirected through a phishing attack or drive-by download.\u003c/li\u003e\n\u003cli\u003eThe victim\u0026rsquo;s Chrome browser attempts to render the malicious HTML and execute the embedded JavaScript code.\u003c/li\u003e\n\u003cli\u003eThe crafted JavaScript code exploits the type confusion vulnerability in the V8 engine, leading to an incorrect type assignment.\u003c/li\u003e\n\u003cli\u003eThe type confusion results in an out-of-bounds memory access, allowing the attacker to read or write to arbitrary memory locations.\u003c/li\u003e\n\u003cli\u003eThe attacker leverages the ability to read and write to arbitrary memory locations to inject and execute malicious code within the Chrome process.\u003c/li\u003e\n\u003cli\u003eThe attacker gains control of the Chrome process and can perform actions such as stealing cookies, injecting keyloggers, or accessing sensitive information.\u003c/li\u003e\n\u003cli\u003eThe attacker may pivot from the compromised browser to other systems on the network, depending on the environment and attacker objectives.\u003c/li\u003e\n\u003c/ol\u003e\n\u003ch2 id=\"impact\"\u003eImpact\u003c/h2\u003e\n\u003cp\u003eSuccessful exploitation of CVE-2026-6363 can lead to arbitrary code execution within the context of the Chrome browser.
