Google fixes Chrome zero-day with in-the-wild exploit (CVE-2024-4671)
Google has fixed a Chrome zero-day vulnerability (CVE-2024-4671), an exploit for which exists in the wild.
About CVE-2024-4671
CVE-2024-4671 is a use after free vulnerability in the Visuals component that can be exploited by remote attackers to trigger an exploitable heap corruption via a specially crafted HTML page.
“Successful exploitation of this vulnerability could allow for arbitrary code execution in the context of the logged on user. Depending on the privileges associated with the user an attacker could then install programs; view, change, or delete data; or create new accounts with full user rights,” CIS explains.
“Users whose accounts are configured to have fewer user rights on the system could be less impacted than those who operate with administrative user rights.”
The zero-day has been reported by an anonymous bug hunter and, according to Google, there’s an in-the-wild exploit for it. Though the company doesn’t explicitly say that the exploit is being used by attackers, chances are good that it is – or very soon will be.

The vulnerability has been fixed in the stable desktop versions of Google Chrome:
- v124.0.6367.201/.202 for Mac and Windows
- v124.0.6367.201 for Linux
“The Extended Stable channel has been updated to 124.0.6367.201 for Mac and Windows which will roll out over the coming days/weeks,” the company added.
