CVE-2025-13224 Overview
CVE-2025-13224 is a type confusion vulnerability in the V8 JavaScript engine used by Google Chrome. The flaw affects Chrome versions prior to 142.0.7444.175 across Windows, macOS, and Linux platforms. A remote attacker can exploit heap corruption by serving a crafted HTML page to a target user. Google's Chrome team rated the underlying issue as High severity in their internal Chromium security tracking. The vulnerability is classified under CWE-843: Access of Resource Using Incompatible Type.
Critical Impact
A remote attacker who convinces a user to visit a malicious web page can trigger heap corruption inside V8 and potentially achieve arbitrary code execution within the renderer process.
Affected Products
- Google Chrome versions prior to 142.0.7444.175

Technical Details for CVE-2025-13224
Vulnerability Analysis
The vulnerability resides in V8, the JavaScript and WebAssembly engine that powers Chrome's renderer process. Type confusion occurs when code allocates or accesses a resource using one type but later operates on it as a different, incompatible type. In V8, optimizing compilers such as TurboFan and Maglev rely on hidden classes, maps, and inline caches to specialize object access. When type assumptions break during optimization, the engine reads or writes memory using a layout that does not match the underlying object.
Exploitation typically requires user interaction, namely visiting a crafted page. The resulting heap corruption can be shaped into a read-write primitive that an attacker uses to bypass V8 mitigations and execute code in the sandboxed renderer. Pairing this issue with a sandbox escape would extend impact to the host operating system.
Root Cause
The root cause is improper type validation within V8's handling of JavaScript objects, as captured by [CWE-843]. Specific technical details of the affected V8 component remain restricted in the Chromium Issue Tracker until a majority of users have updated.
Attack Vector
The attack vector is network-based and requires user interaction. An attacker hosts a crafted HTML page containing malicious JavaScript that triggers the type confusion condition. Delivery channels include phishing links, malicious advertisements, compromised legitimate sites, and embedded iframes. No authentication is required, and the renderer process executes the attacker-controlled script with the privileges of the browser user.
No public proof-of-concept or exploit code is available at the time of writing. The vulnerability is not listed on the CISA Known Exploited Vulnerabilities catalog.
Detection Methods for CVE-2025-13224
Indicators of Compromise
- Chrome renderer processes crashing with access violations or segmentation faults shortly after visiting external sites.
- Unexpected child processes spawned by chrome.exe or the Chrome helper renderer on macOS and Linux.
- Outbound connections from Chrome to unfamiliar domains immediately after a crash event, suggesting second-stage payload retrieval.
Detection Strategies
- Inventory Chrome versions across endpoints and flag any installation below 142.0.7444.175.
- Monitor browser telemetry for renderer crashes correlated with specific URLs or ad networks.
- Inspect web proxy logs for HTML responses containing heavy use of typed arrays, ArrayBuffer manipulation, and aggressive JIT warm-up patterns commonly used in V8 exploits.
Monitoring Recommendations
- Centralize endpoint logs to capture Chrome process lineage, command lines, and crash dumps for retrospective hunting.
- Alert on Chrome child processes writing to disk in user-writable directories or executing shell utilities such as powershell.exe, cmd.exe, bash, or osascript.
- Track DNS and HTTP requests from browser processes to newly registered or low-reputation domains.
How to Mitigate CVE-2025-13224
Immediate Actions Required
- Update Google Chrome to version 142.0.7444.175 or later on Windows, macOS, and Linux endpoints.
- Restart all Chrome instances after the update so the patched binaries load into memory.
- Audit Chromium-based browsers such as Microsoft Edge, Brave, Opera, and Vivaldi and apply their corresponding V8 updates.
Patch Information
Google addressed CVE-2025-13224 in the Chrome Stable Channel release 142.0.7444.175 for desktop. Details are published in the Google Chrome Stable Update advisory. Enterprises using managed Chrome deployments should push the update through Group Policy, Chrome Browser Cloud Management, or their endpoint management platform.
Workarounds
- Enforce automatic Chrome updates through enterprise policy until all endpoints report a patched build.
- Restrict JavaScript execution on untrusted sites using site isolation, enterprise URL allow-listing, or content filtering at the proxy.
- Educate users to avoid clicking links in unsolicited messages and to report renderer crashes to the security team.
