CVE-2026-84349
Google · Chrome
A use after free vulnerability in the Google Chrome browser allows a remote attacker to achieve arbitrary code execution outside the sandbox via a crafted HTML page.
Executive summary
A critical use after free vulnerability in Google Chrome allows remote attackers to bypass sandbox protections and execute arbitrary code on the host system.
Vulnerability
This is a use after free vulnerability located in the browser component. It allows an unauthenticated remote attacker who has already compromised the renderer process to escape the sandbox and execute arbitrary code.
Business impact
The ability to escape the browser sandbox and execute arbitrary code poses a severe risk to organizational assets. A successful exploit could lead to full system compromise, unauthorized data exfiltration, or the installation of persistent malware. With a CVSS score of 8.3, this high severity vulnerability warrants immediate attention to prevent potential lateral movement within the network.
Remediation
Immediate Action: Update all Google Chrome installations to version 152.0.7977.75 or later immediately.
Proactive Monitoring: Review system logs for unusual browser activity or unexpected process execution patterns that may indicate a sandbox escape attempt.
Compensating Controls: Ensure that endpoint protection software is active and configured to detect malicious memory patterns or suspicious child processes spawned by the browser.
Exploitation status
Public Exploit Available: Unknown
Analyst recommendation
Given the nature of use after free vulnerabilities and their frequent use in browser based attack chains, organizations must prioritize patching this flaw. Ensure that all managed endpoints receive the update to version 152.0.7977.75 as soon as possible to mitigate the risk of arbitrary code execution.
