Release Date:

Type Confusion Vulnerability in Chrome Browser



  • 28/10/2022 --- v1.0 -- Initial publication


On October 27, 2022, Google released a new version of its Chrome browser fixing a high-severity flaw, identified by CVE-2022-3723 [1]. Google is aware of reports that an exploit for CVE-2022-3723 exists in the wild. It is highly recommended to apply the update.

Technical Details

The CVE-2022-3723 is a type confusion in the V8 engine. Type confusion vulnerabilities arise when a program allocates or initialises a resource such as a pointer, object, or variable using one type, but it later accesses that resource using a type that is incompatible with the original type [2], potentially allowing an attacker to perform out-of-bound memory access.

Google keeps the access to bug details and links restricted until a majority of users are updated with a fix.

Affected Products

  • Google Chrome for Mac, Windows and Linux before version 107.0.5304.87.


CERT-EU recommends updating to the latest version.
