Google has urgently released updates for its Chrome browser to address four security issues, including a critical actively exploited zero-day flaw. The vulnerability, identified as CVE-2024-0519, is an out-of-bounds memory access issue in the V8 JavaScript and WebAssembly engine. This flaw poses a serious threat as it can be exploited to bypass security measures and execute code, potentially leading to system crashes and data breaches.

Details of the Vulnerability:

  • CVE-2024-0519: The vulnerability involves improper memory access in Chrome’s V8 engine. Exploitation can lead to heap corruption, allowing attackers to bypass ASLR and other protection mechanisms. This could result in unauthorized code execution or denial of service.

  • Affected Versions: Google Chrome versions prior to 120.0.6099.224.

Impact and Risks:

This zero-day flaw allows attackers to exploit heap corruption through a crafted HTML page, making it a high-risk vulnerability for any user of the affected Chrome versions. The exploitation of such vulnerabilities can lead to the compromise of sensitive information and system integrity.


  • Immediate Update: Users are strongly advised to update their Chrome browser to version 120.0.6099.224/225 for Windows, 120.0.6099.234 for macOS, and 120.0.6099.224 for Linux.
  • Chromium-based Browsers: Users of browsers like Microsoft Edge, Brave, Opera, and Vivaldi, which are based on Chromium, should also apply updates as soon as they are available.

OP Innovate’s Advisory:

  • Vigilance: Continuously monitor systems for any signs of unusual activity or potential security breaches.
  • Security Best Practices: Maintain up-to-date software, use robust security solutions, and regularly review security protocols.


CVE-2024-0519 represents the first actively exploited zero-day patched by Google in Chrome in 2024. Given the severity and active exploitation of this vulnerability, immediate action is required to ensure system security and integrity.
