Chrome zero-day vulnerability patched

Google just released a patch for their Chrome browser, a Type Confusion flaw which is being actively exploited in the wild.

If you are using the Chrome browser, be sure to update as soon as possible: 114.0.5735.110 for Windows and 114.0.5735.106 for Mac.

Since Microsoft uses the same engine for Edge, it, too, has the flaw. Microsoft is aware of the issue and is actively working on releasing a patch.

This is Google’s third zero-day for the year.

CVE-2023-3079
