CVE-2025-11211: Google Chrome RCE Vulnerability

CVE-2025-11211 Overview

CVE-2025-11211 is an out-of-bounds read vulnerability (CWE-125) in the Media component of Google Chrome prior to version 141.0.7390.54. This vulnerability allows a remote attacker to potentially perform out-of-bounds memory access via a crafted HTML page. The flaw could enable unauthorized access to sensitive memory contents, potentially exposing confidential information processed by the browser.

Critical Impact

Remote attackers can exploit this vulnerability to read memory beyond intended boundaries, potentially leaking sensitive information such as authentication tokens, session data, or other confidential browser memory contents.

Affected Products

• Google Chrome versions prior to 141.0.7390.54
• Google Chrome on Microsoft Windows
• Google Chrome on Apple macOS
• Google Chrome on Linux

Technical Details for CVE-2025-11211

Vulnerability Analysis

This out-of-bounds read vulnerability exists in Chrome's Media component, which handles various multimedia operations including audio and video processing. The flaw allows attackers to craft malicious HTML content that triggers memory access beyond the allocated buffer boundaries during media parsing or rendering operations.

When exploited, an attacker can read memory contents from locations outside the intended data structure. This type of vulnerability is particularly concerning in browser environments as it can expose sensitive data from other processes, browser tabs, or internal Chrome memory structures. The attack can be delivered remotely through any mechanism that renders HTML content in Chrome, including visiting a malicious website or viewing compromised advertising content.

Root Cause

The vulnerability stems from insufficient bounds checking in the Media component's memory access operations. When processing specially crafted media-related content within HTML pages, the component fails to properly validate array indices or pointer offsets, resulting in read operations that exceed buffer boundaries. This represents a classic memory safety issue categorized under CWE-125 (Out-of-bounds Read).

Attack Vector

The attack is network-based and requires no user authentication or special privileges. An attacker needs to convince a victim to visit a malicious webpage or otherwise load crafted HTML content containing the exploit payload. The attack does not require user interaction beyond initially loading the page, making it suitable for watering hole attacks or malvertising campaigns.

The exploitation mechanism involves embedding specially crafted media elements or attributes within an HTML page that trigger the vulnerable code path in Chrome's Media component. When the browser attempts to parse or render this content, the out-of-bounds read occurs, potentially disclosing memory contents to the attacker.

Detection Methods for CVE-2025-11211

Indicators of Compromise

• Unusual crash reports or memory access violations in Chrome's Media component
• Network traffic containing anomalous HTML pages with suspicious media element configurations
• Browser process memory dumps indicating out-of-bounds access patterns
• Chrome error logs referencing Media component failures during page rendering

Detection Strategies

• Monitor Chrome process behavior for unexpected memory access patterns using endpoint detection and response (EDR) solutions
• Implement network-based detection for HTML content containing known exploit patterns targeting this vulnerability
• Deploy web application firewalls (WAF) rules to filter potentially malicious media-related HTML constructs
• Utilize SentinelOne's behavioral AI to detect anomalous browser component behavior indicative of memory exploitation attempts

Monitoring Recommendations

• Enable Chrome's built-in security telemetry and monitor for Media component anomalies
• Configure SIEM rules to alert on Chrome crash reports with memory violation signatures
• Implement browser version monitoring across the enterprise to identify unpatched Chrome installations
• Deploy continuous vulnerability scanning to maintain visibility into Chrome version compliance

How to Mitigate CVE-2025-11211

Immediate Actions Required

• Update Google Chrome to version 141.0.7390.54 or later immediately across all managed endpoints
• Verify Chrome auto-update functionality is enabled and functioning properly
• Prioritize patching for systems with access to sensitive data or external internet content
• Consider temporarily restricting access to untrusted websites on critical systems until patching is complete

Patch Information

Google has released a security update addressing this vulnerability in Chrome version 141.0.7390.54. The fix is available through the stable channel for all supported platforms including Windows, macOS, and Linux. Organizations should update Chrome immediately via the Google Chrome Desktop Update.

For enterprise environments, administrators can push the update through Chrome Browser Cloud Management or Group Policy. Additional technical details about the vulnerability can be found in the Chromium Issue Tracker #441917796.

Workarounds

• If immediate patching is not possible, consider using alternative browsers for high-risk activities until Chrome can be updated
• Implement strict web filtering policies to block access to untrusted or unknown websites
• Enable Chrome's Site Isolation feature to limit potential information exposure between sites
• Deploy network segmentation to reduce the impact of potential information disclosure from compromised browsers
