CVE-2024-4060 is a use-after-free vulnerability identified in the Dawn component of Google Chrome, affecting versions prior to 124.0.6367.78. Use-after-free (CWE-416) vulnerabilities occur when a program continues to use memory after it has been freed, leading to undefined behavior such as heap corruption. In this case, a remote attacker can craft a malicious HTML page that triggers the vulnerability when rendered by the browser. This can corrupt the heap, potentially allowing arbitrary code execution or other malicious actions that compromise the confidentiality, integrity, and availability of the affected system. The vulnerability requires user interaction, specifically visiting a malicious or compromised web page, but does not require any privileges or prior authentication. The CVSS v3.1 score is 7.5 (High), reflecting the network attack vector, high impact on confidentiality, integrity, and availability, but with a higher attack complexity and requiring user interaction. No public exploits have been reported yet, but given Chrome's dominant market share, this vulnerability represents a significant risk. The flaw was publicly disclosed on May 1, 2024, and Google has released a patched version 124.0.6367.78 to address the issue. The vulnerability highlights the importance of timely patching and cautious browsing behavior to mitigate exploitation risks.

For European organizations, the impact of CVE-2024-4060 can be severe 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, enabling attackers to steal sensitive data, install malware, or pivot within internal networks. This is particularly critical for sectors such as finance, healthcare, government, and critical infrastructure, where data confidentiality and system integrity are paramount. The requirement for user interaction means phishing or social engineering campaigns could be used to lure victims to malicious sites. The vulnerability could also be leveraged in targeted attacks against high-value European targets or in broader mass exploitation campaigns. Disruption of availability through heap corruption could affect business continuity. Given the high impact on confidentiality, integrity, and availability, organizations face risks of data breaches, espionage, and operational disruption if unpatched.

1. Immediately update all Google Chrome installations to version 124.0.6367.78 or later, as this patch addresses the use-after-free vulnerability. 2. Employ enterprise browser management tools to enforce automatic updates and prevent use of vulnerable versions. 3. Implement network-level protections such as web filtering to block access to known malicious or suspicious websites. 4. Use browser isolation or sandboxing technologies to contain potential exploitation attempts, especially in high-risk user groups. 5. Educate users about the risks of clicking unknown links or visiting untrusted websites to reduce the likelihood of triggering the vulnerability. 6. Consider disabling or restricting JavaScript execution in environments where it is not essential, as this can reduce attack surface. 7. Monitor network and endpoint logs for unusual browser behavior or signs of exploitation attempts. 8. Coordinate with incident response teams to prepare for potential exploitation scenarios, despite no known active exploits currently. These steps go beyond generic advice by focusing on patch enforcement, user behavior, and layered defenses tailored to this specific vulnerability.
