CVE-2024-0518 is a type confusion vulnerability identified in the V8 JavaScript engine component of Google Chrome, affecting versions prior to 120.0.6099.224. Type confusion occurs when a program incorrectly interprets the type of an object, leading to memory corruption. In this case, the flaw allows a remote attacker to craft a malicious HTML page that triggers heap corruption within the V8 engine. Heap corruption can lead to arbitrary code execution, enabling attackers to run code with the privileges of the browser process. The vulnerability is exploitable remotely over the network without requiring prior authentication, but it does require user interaction, such as visiting a malicious or compromised website. The CVSS v3.1 score of 7.5 indicates a high severity, with the vector string AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:H showing that the attack vector is network-based, requires high attack complexity, no privileges, user interaction, unchanged scope, and high impact on confidentiality, integrity, and availability. Although no known exploits have been reported in the wild yet, the nature of the vulnerability and its presence in a widely used browser make it a significant risk. The vulnerability is categorized under CWE-843 (Type Confusion), a common source of memory safety issues leading to serious exploitation scenarios. Google has released a patched version (120.0.6099.224) to address this issue, but no direct patch links were provided in the source data. Organizations relying on Chrome should prioritize updating to the fixed version to mitigate potential exploitation.

For European organizations, this vulnerability poses a significant risk due to the widespread use of Google Chrome as the primary web browser. Successful exploitation can lead to arbitrary code execution within the browser context, potentially allowing attackers to bypass security controls, steal sensitive data, or deploy further malware. This is particularly critical for sectors with high exposure to web threats such as finance, government, healthcare, and critical infrastructure. The requirement for user interaction means phishing or drive-by download attacks could be effective vectors. Given the high impact on confidentiality, integrity, and availability, exploitation could result in data breaches, operational disruptions, and reputational damage. Additionally, organizations with remote or hybrid workforces relying on Chrome for internet access may face increased exposure. The absence of known exploits in the wild currently provides a window for proactive patching and mitigation, but the risk remains elevated due to the vulnerability’s nature and severity.

1. Immediately update all Google Chrome installations to version 120.0.6099.224 or later, which contains the fix for CVE-2024-0518. 2. Enforce automated browser update policies across enterprise environments to ensure timely patch deployment. 3. Implement network-level protections such as web filtering and intrusion prevention systems (IPS) to block access to known malicious sites that could host exploit pages. 4. Educate users about the risks of clicking on suspicious links or visiting untrusted websites to reduce the likelihood of user interaction-based exploitation. 5. Employ endpoint detection and response (EDR) solutions capable of detecting anomalous browser behavior indicative of exploitation attempts. 6. Monitor security advisories from Google and Chromium project for any updates or emerging exploit reports related to this vulnerability. 7. Consider sandboxing or isolating browser processes where feasible to limit the impact of potential exploitation. 8. Review and tighten browser security configurations, including disabling unnecessary plugins or extensions that could increase attack surface.
