CVE-2024-3832 Overview
CVE-2024-3832 is an object corruption vulnerability in the V8 JavaScript engine used by Google Chrome. The vulnerability exists in versions prior to 124.0.6367.60 and allows a remote attacker to potentially exploit object corruption via a crafted HTML page. This type of memory corruption vulnerability in V8 can lead to arbitrary code execution within the browser's renderer process, making it a significant security concern for Chrome users.
Critical Impact
Remote attackers can exploit this V8 object corruption to potentially achieve arbitrary code execution by convincing users to visit a malicious webpage containing specially crafted JavaScript code.
Affected Products
- Google Chrome versions prior to 124.0.6367.60
- Fedora 38 (chromium package)
- Fedora 39 (chromium package)
- Fedora 40 (chromium package)

Technical Details for CVE-2024-3832
Vulnerability Analysis
This vulnerability involves object corruption within V8, Chrome's JavaScript and WebAssembly engine. Object corruption vulnerabilities in V8 typically occur when the engine's internal representation of JavaScript objects becomes inconsistent or corrupted during execution. This can happen due to improper handling of object properties, incorrect type assumptions during optimization passes, or issues in the garbage collection process.
V8 uses sophisticated optimization techniques including Just-In-Time (JIT) compilation that can create opportunities for object corruption when type confusion or improper bounds checking occurs. When an attacker can corrupt object metadata or internal pointers, they may be able to achieve arbitrary read/write primitives that can be chained to gain code execution.
The vulnerability is classified under CWE-119 (Improper Restriction of Operations within the Bounds of a Memory Buffer), indicating that the flaw involves memory safety issues where operations are performed outside expected boundaries.
Root Cause
The root cause of this vulnerability lies in improper memory safety handling within the V8 JavaScript engine. Object corruption can stem from several potential sources in V8's architecture including type confusion during JIT optimization, improper bounds validation during array or object property access, or race conditions in concurrent garbage collection routines. The specific root cause involves operations that violate the integrity of V8's internal object representation.
Attack Vector
The attack vector for CVE-2024-3832 is network-based and requires user interaction. An attacker must craft a malicious HTML page containing JavaScript code designed to trigger the object corruption condition in V8. The attack proceeds as follows:
- Attacker creates a webpage with specially crafted JavaScript that triggers the object corruption
- Victim is lured to visit the malicious page through phishing, malvertising, or compromised legitimate websites
- Chrome's V8 engine processes the malicious JavaScript, triggering the corruption
- The corrupted object state can be leveraged to gain further memory access or code execution
The vulnerability can be exploited entirely through web content delivery, making it particularly dangerous as no additional plugins or downloads are required.
Detection Methods for CVE-2024-3832
Indicators of Compromise
- Unusual Chrome renderer process crashes or unexpected behavior during web browsing
- JavaScript errors or exceptions related to type mismatches in browser console logs
- Anomalous memory allocation patterns from Chrome processes
- Suspicious network connections following visits to untrusted websites
Detection Strategies
- Monitor for Chrome renderer process crashes that may indicate exploitation attempts
- Implement browser isolation or sandboxing solutions that can contain V8 exploitation
- Deploy network security monitoring to detect connections to known malicious domains hosting exploit pages
- Utilize endpoint detection solutions capable of identifying suspicious browser behavior patterns
Monitoring Recommendations
- Enable Chrome's enhanced protection mode for real-time threat detection
- Monitor endpoint telemetry for unusual Chrome child process activity
- Review browser history and network logs for visits to suspicious or newly registered domains
- Implement web filtering to block access to known malicious sites serving browser exploits
How to Mitigate CVE-2024-3832
Immediate Actions Required
- Update Google Chrome to version 124.0.6367.60 or later immediately
- Enable automatic updates in Chrome to ensure timely delivery of security patches
- For Fedora users, apply the security updates through dnf update chromium
- Consider restricting access to untrusted websites until patching is complete
Patch Information
Google has addressed this vulnerability in Chrome version 124.0.6367.60, released on April 16, 2024. The fix was announced in the Google Chrome Update Announcement. Additional details about the vulnerability can be found in the Chromium Issue Tracker Entry.
Fedora has released security updates for Fedora 38, 39, and 40 to address this vulnerability:
Workarounds
- Enable Chrome's Site Isolation feature if not already active to limit cross-site exploitation
- Use browser extensions that block JavaScript execution on untrusted sites
- Consider using Chrome's incognito mode when visiting unfamiliar websites to limit exposure
- Implement network-level blocking of known malicious domains that may host exploitation attempts
# Verify Chrome version on Linux/macOS
google-chrome --version
# Expected output: Google Chrome 124.0.6367.60 or higher
# Update Chromium on Fedora
sudo dnf update chromium --refresh
# Verify Chromium version after update
chromium-browser --version
