CVE-2025-0437 Overview
CVE-2025-0437 is an out-of-bounds read vulnerability in the Metrics component of Google Chrome prior to version 132.0.6834.83. This memory corruption flaw allows a remote attacker to potentially exploit heap corruption via a crafted HTML page. The vulnerability has been classified as High severity by Chromium security.
Critical Impact
A remote attacker can exploit this out-of-bounds read vulnerability to potentially corrupt heap memory, which could lead to arbitrary code execution, information disclosure, or browser crashes when a user visits a malicious webpage.

Technical Details for CVE-2025-0437
Vulnerability Analysis
This vulnerability exists within the Metrics component of Google Chrome, which is responsible for collecting and processing browser telemetry data. The out-of-bounds read (CWE-125) occurs when the Metrics component improperly handles memory boundaries during data processing operations.
Out-of-bounds read vulnerabilities allow an attacker to read memory outside the intended buffer boundaries. In the context of a web browser like Chrome, this type of vulnerability can be particularly dangerous as it may lead to information disclosure or serve as a primitive for more complex exploitation chains. When combined with heap corruption, attackers may be able to manipulate heap metadata or adjacent objects to achieve code execution.
The attack requires user interaction—specifically, the victim must navigate to an attacker-controlled webpage containing specially crafted HTML content designed to trigger the vulnerable code path in the Metrics component.
Root Cause
The root cause of CVE-2025-0437 is improper bounds checking within the Metrics component of Google Chrome. When processing certain data structures, the component fails to properly validate array indices or buffer offsets, allowing read operations to occur beyond the allocated memory region. This can lead to heap corruption when the out-of-bounds data is subsequently used in memory management operations.
Attack Vector
The attack vector for this vulnerability is network-based, requiring minimal attacker complexity but necessitating user interaction. An attacker would craft a malicious HTML page designed to trigger the vulnerable code path in Chrome's Metrics component. When a victim visits this page, the browser processes the malicious content, triggering the out-of-bounds read condition.
The exploitation flow typically involves:
- Attacker creates a malicious webpage with specially crafted HTML/JavaScript content
- Victim is lured to visit the malicious page through phishing or other social engineering techniques
- Chrome's Metrics component processes the page content and triggers the out-of-bounds read
- The read operation accesses memory beyond the intended buffer, potentially leading to heap corruption
- Attacker may leverage the heap corruption to achieve further compromise
For detailed technical information about this vulnerability, see the Chromium Issue #378623799 and the Google Chrome Update Announcement.
Detection Methods for CVE-2025-0437
Indicators of Compromise
- Unusual Chrome process crashes or memory-related errors in browser logs
- Unexpected browser behavior when visiting certain websites
- Memory dump artifacts showing heap corruption patterns in Chrome processes
- Network traffic to suspicious domains serving crafted HTML content
Detection Strategies
- Monitor for Chrome crash reports related to the Metrics component or heap memory issues
- Deploy endpoint detection rules to identify exploitation attempts targeting browser memory vulnerabilities
- Utilize SentinelOne's behavioral AI to detect anomalous Chrome process behavior indicative of memory corruption exploitation
- Implement network security monitoring for suspicious web traffic patterns
Monitoring Recommendations
- Enable Chrome's built-in crash reporting and review for patterns related to heap corruption
- Deploy SentinelOne agents to monitor browser process behavior and detect exploitation attempts in real-time
- Review web proxy logs for access to known malicious domains or suspicious HTML content delivery
- Implement browser extension or security policy to warn users about potentially dangerous sites
How to Mitigate CVE-2025-0437
Immediate Actions Required
- Update Google Chrome to version 132.0.6834.83 or later immediately
- Enable automatic updates for Google Chrome to ensure timely security patches
- Educate users about the risks of visiting untrusted websites
- Consider implementing browser isolation solutions for high-risk browsing activities
Patch Information
Google has addressed this vulnerability in Chrome version 132.0.6834.83, released on January 14, 2025. Organizations should prioritize updating all Chrome installations to this version or later. The update can be obtained through Chrome's built-in update mechanism or from the official Google Chrome download page. For enterprise environments, administrators should deploy the update through their software distribution systems.
For more details, refer to the Google Chrome Update Announcement.
Workarounds
- Restrict browsing to trusted websites only until the patch can be applied
- Use alternative browsers temporarily if Chrome cannot be updated immediately
- Implement network-level filtering to block known malicious domains
- Enable Chrome's Site Isolation feature for additional process-level protection
- Consider using browser extensions that block potentially malicious scripts
# Verify Chrome version on Linux/macOS
google-chrome --version
# Force Chrome update check
# Navigate to: chrome://settings/help
# Or restart Chrome with update flag
