CVE-2025-11211 is an out-of-bounds read vulnerability identified in the Media component of Google Chrome prior to version 141.0.7390.54. This vulnerability arises from improper bounds checking when processing media content, which can be triggered by a remote attacker through a crafted HTML page containing malicious media elements. The flaw allows the attacker to read memory outside the intended buffer boundaries, potentially exposing sensitive information from the browser's memory space. The vulnerability does not require any privileges or user interaction, making it remotely exploitable simply by convincing a user to visit a malicious webpage. The CVSS v3.1 base score is 7.5, reflecting a high severity level primarily due to its network attack vector, low attack complexity, and high impact on confidentiality. However, it does not affect integrity or availability. No public exploits have been reported yet, but the vulnerability is considered serious given the widespread use of Chrome. The underlying weakness corresponds to CWE-125 (Out-of-bounds Read), a common memory safety issue that can lead to information disclosure. The vulnerability was reserved on 2025-09-30 and published on 2025-11-06, indicating a recent discovery and disclosure. No patch links were provided in the data, but updating to Chrome 141.0.7390.54 or later is the recommended remediation.

For European organizations, this vulnerability poses a significant risk of confidential data leakage through memory disclosure when users browse malicious websites. Since Chrome is widely used across Europe in both enterprise and consumer environments, the potential attack surface is large. Sensitive information such as authentication tokens, personal data, or corporate secrets stored in browser memory could be exposed. Although the vulnerability does not allow code execution or system compromise, the confidentiality breach can facilitate further attacks like session hijacking or targeted phishing. The lack of required privileges or user interaction increases the risk of automated exploitation campaigns. Critical sectors such as finance, healthcare, and government agencies in Europe could be targeted due to the value of the information accessible via browser memory. The impact on integrity and availability is negligible, but the confidentiality impact alone justifies urgent mitigation. The absence of known exploits in the wild currently reduces immediate risk but does not eliminate the threat, especially given the public disclosure.

European organizations should prioritize updating all instances of Google Chrome to version 141.0.7390.54 or later as soon as possible to remediate this vulnerability. Network-level protections such as web filtering and blocking access to known malicious or untrusted websites can reduce exposure. Employing endpoint detection and response (EDR) solutions with behavioral analytics may help identify anomalous browser activity indicative of exploitation attempts. Security awareness training should emphasize caution when visiting unknown or suspicious websites, even though no user interaction is required for exploitation. Organizations should also monitor threat intelligence feeds for any emerging exploit code or attack campaigns related to CVE-2025-11211. Implementing Content Security Policy (CSP) headers and sandboxing browser tabs can provide additional layers of defense. Regular vulnerability scanning and patch management processes must be enforced to ensure timely updates. Finally, consider isolating high-risk browsing activities or using dedicated browsers for sensitive tasks to limit potential exposure.
