CVE-2025-11219 is a use-after-free vulnerability identified in the V8 JavaScript engine component of Google Chrome prior to version 141.0.7390.54. Use-after-free bugs occur when a program continues to use memory after it has been freed, leading to undefined behavior such as out-of-bounds memory access. In this case, a remote attacker can exploit the flaw by crafting a malicious HTML page that, when loaded by a victim's browser, triggers the vulnerability. This could potentially allow the attacker to read memory beyond the intended bounds, which may lead to information disclosure. However, the vulnerability does not allow for code execution or modification of data, as indicated by the CVSS vector (Confidentiality: Low, Integrity: None, Availability: None). The attack requires user interaction (visiting a malicious page) and has a high attack complexity, meaning exploitation is not straightforward. No privileges are required, and the scope is unchanged, affecting only the vulnerable browser instance. Google has assigned a low severity rating and no known exploits have been reported in the wild. The vulnerability was published on November 6, 2025, and users are advised to update to version 141.0.7390.54 or later where the issue is fixed.

For European organizations, the primary impact of CVE-2025-11219 is limited to potential confidentiality breaches through out-of-bounds memory reads in affected Chrome browsers. Since the vulnerability does not allow code execution or denial of service, the risk to system integrity and availability is minimal. However, in environments where sensitive information is accessed via Chrome, such as financial institutions, healthcare providers, or government agencies, even limited data leakage could have compliance and privacy implications under regulations like GDPR. The requirement for user interaction reduces the likelihood of widespread automated exploitation, but targeted phishing or watering hole attacks could leverage this vulnerability to gather sensitive data. Organizations with large numbers of users on outdated Chrome versions may face increased exposure. The absence of known exploits in the wild suggests a low immediate threat, but the vulnerability should not be ignored as part of a layered defense strategy.

European organizations should implement the following specific mitigations: 1) Ensure all Chrome browsers are updated to version 141.0.7390.54 or later promptly, using centralized patch management tools where possible. 2) Enforce policies that restrict or monitor the execution of untrusted or unknown web content, including the use of browser security extensions or content filtering solutions. 3) Educate users about the risks of visiting suspicious websites and the importance of avoiding clicking on unknown links, especially in emails or messaging platforms. 4) Employ network-level protections such as web proxies or secure web gateways that can detect and block access to malicious sites hosting crafted HTML pages. 5) Monitor browser telemetry and logs for unusual behavior that might indicate exploitation attempts. 6) Integrate vulnerability scanning and browser version inventory into regular security audits to ensure compliance. These steps go beyond generic advice by focusing on operational controls and user awareness tailored to this specific vulnerability.
