Security experts indicate that successful exploitation of this vulnerability would likely begin with a specially crafted webpage containing JavaScript code designed to trigger memory corruption. The high-severity Vulnerability tracked as CVE-2025-3066 could allow attackers to execute arbitrary code on affected systems, potentially taking complete control of victims’ devices when successfully exploited. As is standard practice with severe vulnerabilities, Google has restricted access to complete technical details until a majority of users have been updated with the security patch. The vulnerability tracked as CVE-2025-3066 stems from a memory management flaw known as a “Use After Free” (UAF) bug in Chrome’s Site Isolation feature. Cyber Security News is a Dedicated News Platform For Cyber News, Cyber Attack News, Hacking News & Vulnerability Analysis. Security experts strongly recommend that all Chrome users update their browsers to the latest version immediately. Use After Free vulnerabilities occur when a program continues to use a memory location after it has been freed, creating a scenario where attackers can manipulate the contents of that freed memory. In typical exploitation scenarios, this allows attackers to corrupt memory and potentially execute malicious code. When a victim visits such a page, the malicious code could manipulate the freed memory region, leading to arbitrary code execution. Site Isolation is a security mechanism introduced to mitigate side-channel attacks like Spectre by ensuring websites are rendered in separate processes. Security researcher Sven Dysthe (@svn-dys) reported the vulnerability on March 21, 2025. Chrome users can verify their browser version and update their status by navigating to “chrome://settings/help” in the address bar.
