CVE-2025-10200 Overview
CVE-2025-10200 is a use-after-free vulnerability in the Serviceworker component of Google Chrome on Desktop prior to version 140.0.7339.127. This memory corruption flaw allows a remote attacker to potentially exploit heap corruption via a crafted HTML page, potentially leading to arbitrary code execution within the context of the browser process. The vulnerability is classified as critical severity by Chromium security.
Critical Impact
Remote attackers can exploit heap corruption through malicious web content, potentially achieving code execution with user privileges on affected systems running vulnerable Chrome versions.
Affected Products
- Google Chrome prior to version 140.0.7339.127
- Google Chrome on Microsoft Windows
- Google Chrome on Apple macOS
- Google Chrome on Linux

Technical Details for CVE-2025-10200
Vulnerability Analysis
This vulnerability is classified as CWE-416 (Use After Free), a memory corruption condition that occurs when a program continues to reference memory after it has been freed. In the context of the Serviceworker component, this can lead to heap corruption that attackers can leverage to gain control over program execution.
Serviceworkers are background scripts that run separately from web pages and enable features like push notifications, background sync, and offline functionality. The use-after-free condition in this component can be triggered when processing specially crafted HTML content, making it exploitable through standard web browsing.
The attack requires user interaction—specifically, a victim must navigate to a malicious webpage. Once triggered, the heap corruption can potentially allow an attacker to execute arbitrary code with the same privileges as the Chrome browser process.
Root Cause
The root cause lies in improper memory management within the Serviceworker implementation. When certain objects are freed but subsequently accessed without proper validation, the freed memory may be reallocated for other purposes. This creates a situation where the program operates on corrupted or attacker-controlled data, leading to exploitable heap corruption.
Attack Vector
The vulnerability is exploitable over the network, requiring a victim to visit a malicious webpage containing crafted HTML content. The attack complexity is low, requiring no special privileges on the part of the attacker, though user interaction is necessary to trigger the exploit.
An attacker would typically:
- Create a malicious webpage with specially crafted HTML designed to trigger the use-after-free condition
- Lure victims to the malicious page through phishing, malvertising, or compromised websites
- Exploit the resulting heap corruption to potentially execute arbitrary code
The attack can be delivered through various vectors including malicious advertisements, compromised legitimate websites, or direct phishing campaigns.
Detection Methods for CVE-2025-10200
Indicators of Compromise
- Unusual Chrome crash patterns, particularly related to Serviceworker operations
- Chrome process spawning unexpected child processes or exhibiting anomalous behavior
- Browser memory usage anomalies or heap corruption-related crash dumps
- Suspicious network activity originating from Chrome processes after visiting unknown sites
Detection Strategies
- Monitor Chrome crash reports for patterns indicating heap corruption or use-after-free exploitation attempts
- Implement endpoint detection and response (EDR) solutions to identify anomalous behavior from browser processes
- Deploy network security monitoring to detect communication with known malicious infrastructure
- Configure SentinelOne Singularity platform to detect behavioral indicators of browser-based exploitation
Monitoring Recommendations
- Enable Chrome's built-in crash reporting to identify potential exploitation attempts
- Monitor for unusual process creation chains originating from Chrome processes
- Implement logging for Serviceworker-related activities when possible
- Review endpoint telemetry for indicators of post-exploitation behavior following browser activity
How to Mitigate CVE-2025-10200
Immediate Actions Required
- Update Google Chrome to version 140.0.7339.127 or later immediately
- Enable automatic updates in Chrome to ensure timely receipt of security patches
- Consider disabling JavaScript or using browser isolation for high-risk browsing activities
- Educate users about the risks of visiting untrusted websites
Patch Information
Google has released a security update addressing this vulnerability in Chrome version 140.0.7339.127. The patch is available through standard Chrome update channels. Organizations should prioritize deployment of this update given the potential for remote code execution.
For detailed patch information, refer to the Google Chrome Release Update. Additional technical details may be available in the Chromium Issue Tracker Entry.
Workarounds
- Deploy browser isolation solutions to contain potential exploitation attempts
- Restrict access to untrusted websites through web filtering proxies
- Consider using alternative browsers until Chrome can be updated in enterprise environments
- Implement network-level controls to block known malicious domains and content
# Verify Chrome version on Linux/macOS
google-chrome --version
# or
/Applications/Google\ Chrome.app/Contents/MacOS/Google\ Chrome --version
# Force Chrome update check (restart required after update)
# Navigate to: chrome://settings/help
# Chrome will automatically check and download updates
