CVE-2024-3914 Overview
CVE-2024-3914 is a use-after-free vulnerability in the V8 JavaScript engine used by Google Chrome. This memory corruption flaw allows remote attackers to potentially exploit heap corruption through a specially crafted HTML page. The vulnerability was addressed in Google Chrome version 124.0.6367.60 and has been rated as high severity by the Chromium security team.
Critical Impact
Remote attackers can exploit this use-after-free condition in Chrome's V8 engine to cause heap corruption, potentially leading to denial of service or arbitrary code execution when users visit malicious websites.
Affected Products
- Google Chrome versions prior to 124.0.6367.60
- Fedora 38 (bundled Chromium packages)
- Fedora 39 and Fedora 40 (bundled Chromium packages)

Technical Details for CVE-2024-3914
Vulnerability Analysis
This vulnerability is classified as CWE-416 (Use After Free), a dangerous memory corruption condition that occurs when a program continues to use a pointer after the memory it references has been freed. In the context of Chrome's V8 JavaScript engine, this type of flaw can be triggered through malicious JavaScript code embedded in crafted HTML pages.
V8 is Chrome's high-performance JavaScript and WebAssembly engine, responsible for parsing and executing JavaScript code. Use-after-free vulnerabilities in V8 are particularly concerning because they can be triggered simply by visiting a malicious webpage, requiring no additional user interaction beyond normal browsing activity.
When exploited, this vulnerability allows attackers to corrupt heap memory, which can lead to crashes (denial of service) or potentially enable arbitrary code execution within the browser's sandbox. The network-based attack vector means exploitation can occur remotely through the delivery of malicious web content.
Root Cause
The root cause lies in improper memory management within the V8 JavaScript engine. A use-after-free condition occurs when the engine deallocates a memory object but fails to nullify or invalidate all references to that object. Subsequent operations that attempt to access the freed memory lead to undefined behavior, as the memory region may have been reallocated for other purposes or contain corrupted data.
Attack Vector
Exploitation requires user interaction—specifically, the victim must navigate to or be redirected to a malicious webpage containing the crafted HTML and JavaScript payload. The attack flow typically involves:
- Attacker hosts malicious content on a controlled domain or compromises a legitimate website
- Victim navigates to the malicious page
- Crafted JavaScript triggers the use-after-free condition in V8
- Heap corruption occurs, potentially leading to code execution or browser crash
Since no public exploit code has been identified, the specific trigger mechanism remains undisclosed to prevent active exploitation. Technical details are available in the Chromium Issue Tracker Entry.
Detection Methods for CVE-2024-3914
Indicators of Compromise
- Unexpected browser crashes or instability when visiting specific websites
- Anomalous V8 engine behavior or memory access violations in crash dumps
- Browser process crashes with heap corruption signatures
- Suspicious JavaScript execution patterns in network traffic analysis
Detection Strategies
- Monitor for Chrome browser versions prior to 124.0.6367.60 across enterprise endpoints
- Implement endpoint detection rules to identify V8 crash patterns consistent with use-after-free exploitation
- Deploy network-based detection for known malicious domains serving exploitation attempts
- Review browser crash telemetry for heap corruption indicators
Monitoring Recommendations
- Enable Chrome crash reporting and analyze crash signatures for exploitation indicators
- Utilize SentinelOne's behavioral AI to detect anomalous browser process behavior
- Monitor for unusual child process spawning from Chrome renderer processes
- Implement browser version compliance monitoring across the organization
How to Mitigate CVE-2024-3914
Immediate Actions Required
- Update Google Chrome to version 124.0.6367.60 or later immediately
- Enable automatic Chrome updates to ensure timely patch deployment
- For Fedora users, apply the latest Chromium package updates from the official repositories
- Consider temporarily restricting access to untrusted websites until patching is complete
Patch Information
Google addressed this vulnerability in the Chrome stable channel update released in April 2024. The fix is included in Chrome version 124.0.6367.60 and all subsequent releases. For detailed patch information, refer to the Chrome Stable Update Announcement.
Fedora users should update their Chromium packages through the standard package management system. Multiple Fedora Package Announcements have been issued for Fedora 38, 39, and 40 with the patched versions.
Workarounds
- Restrict browsing to trusted websites until patches can be applied
- Consider using enterprise browser isolation solutions to contain potential exploitation
- Enable site isolation features if not already active in Chrome
- Deploy network security controls to block access to known malicious domains
# Verify Chrome version on Linux/macOS
google-chrome --version
