CVE-2024-5498 Overview
CVE-2024-5498 is a use-after-free vulnerability in the Presentation API component of Google Chrome. This memory corruption flaw exists in versions prior to 125.0.6422.141 and allows a remote attacker to potentially exploit heap corruption through a specially crafted HTML page. Chromium has classified this vulnerability with a security severity of High.
Critical Impact
Successful exploitation of this use-after-free vulnerability could allow an attacker to execute arbitrary code, corrupt heap memory, or cause a denial of service condition in affected Chrome browsers through malicious web content.
Affected Products
- Google Chrome versions prior to 125.0.6422.141
- Fedora Project Fedora 39
- Fedora Project Fedora 40

Technical Details for CVE-2024-5498
Vulnerability Analysis
This vulnerability is classified as CWE-416 (Use After Free), a memory corruption vulnerability that occurs when a program continues to use a pointer after it has been freed. In the context of the Presentation API in Google Chrome, this flaw allows attackers to manipulate heap memory through carefully crafted HTML content.
The Presentation API enables web applications to use external displays for presenting web content. When specific sequences of operations are performed against this API, the browser may reference memory that has already been deallocated, leading to heap corruption.
The vulnerability requires user interaction—specifically, a victim must navigate to a malicious web page. Once triggered, the corrupted heap memory can potentially be leveraged for arbitrary code execution within the browser's context, data exfiltration, or application crashes.
Root Cause
The root cause stems from improper memory management within Chrome's Presentation API implementation. During certain API operations, object references may not be correctly tracked or invalidated after memory deallocation. This creates a dangling pointer condition where subsequent operations attempt to access freed memory regions, corrupting the heap structure.
Attack Vector
The attack is conducted over the network, requiring the attacker to deliver a malicious HTML page to the victim. This can be accomplished through various means including:
- Hosting a malicious website and luring users through social engineering
- Injecting malicious content through compromised advertising networks
- Exploiting cross-site scripting vulnerabilities on legitimate websites
When a user visits the crafted page, JavaScript code interacts with the Presentation API in a manner that triggers the use-after-free condition. The vulnerability can be weaponized to achieve arbitrary code execution by carefully manipulating heap allocations to place attacker-controlled data in the freed memory location.
Detection Methods for CVE-2024-5498
Indicators of Compromise
- Unexpected Chrome browser crashes or instability when visiting unfamiliar websites
- Memory access violations or heap corruption errors in Chrome crash dumps
- Anomalous Presentation API calls in browser developer tools or logs
- Suspicious JavaScript payloads attempting to manipulate display presentation contexts
Detection Strategies
- Monitor Chrome crash reports for heap corruption signatures related to presentation contexts
- Deploy web content filtering to block known malicious domains hosting exploit code
- Implement browser isolation solutions to contain potential exploitation attempts
- Enable Chrome's built-in security features and ensure Safe Browsing is active
Monitoring Recommendations
- Review Chrome version deployments across the organization to identify unpatched instances
- Monitor endpoint detection systems for signs of browser-based memory exploitation
- Track Chromium security advisories and the Chromium Issue Tracker for related vulnerability reports
- Correlate network traffic patterns with known indicators of web-based exploitation campaigns
How to Mitigate CVE-2024-5498
Immediate Actions Required
- Update Google Chrome to version 125.0.6422.141 or later immediately
- Enable automatic updates for Chrome browsers across all managed endpoints
- For Fedora users, apply the latest package updates via dnf update chromium
- Educate users about the risks of visiting untrusted websites
Patch Information
Google has addressed this vulnerability in Chrome version 125.0.6422.141. The fix was released on May 30, 2024, as documented in the Google Chrome Stable Channel Update. Fedora has also released updated packages for Fedora 39 and Fedora 40 addressing this vulnerability, available through the Fedora package announcement.
Workarounds
- Restrict access to untrusted websites using web filtering or proxy solutions
- Consider using browser isolation technology to sandbox untrusted web content
- Disable or limit the Presentation API via Chrome enterprise policies if not required for business operations
- Deploy endpoint protection solutions capable of detecting memory exploitation attempts
# Verify Chrome version on Linux/macOS
google-chrome --version
# Update Chrome on Fedora systems
sudo dnf update chromium
# Chrome Enterprise policy to restrict external display APIs (Windows Registry)
# HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Google\Chrome
# Set "PresentationScreensAllowed" to 0 to restrict Presentation API
