CVE-2026-78909
9.6Google · Chrome
A use-after-free vulnerability in Google Chrome allows remote attackers to execute arbitrary code outside the browser sandbox via a crafted HTML page.
Executive summary
A critical use-after-free vulnerability in Google Chrome allows for remote code execution when a user is lured into interacting with a malicious webpage.
Vulnerability
This is a use-after-free vulnerability in the Views component of the browser. It requires the user to be deceived via social engineering to navigate to a malicious site, at which point an attacker can bypass the browser sandbox.
Business impact
An attacker who successfully exploits this vulnerability can execute arbitrary code on the victim's machine, leading to potential credential theft or persistent system compromise. While the CVSS score is 9.6, the requirement for user interaction slightly lowers the immediate threat compared to fully autonomous exploits.
Remediation
Immediate Action: Update Google Chrome to the latest stable version beyond 152.0.7977.65.
Proactive Monitoring: Utilize endpoint security solutions to monitor for unusual child processes spawned by the Chrome browser.
Compensating Controls: Implement email filtering and browser-based security policies to reduce the likelihood of users encountering malicious HTML content.
Exploitation status
Public Exploit Available: No (No confirmed public exploit in available data)
Analyst recommendation
Browser-based remote code execution vulnerabilities are high-priority targets for attackers. All endpoints running Google Chrome should be updated to the latest version as soon as possible to protect against potential exploitation.
