On Wednesday, Google released a new update for Chrome on Windows, Mac and Linux operating systems. While it's easy to ignore the update button, you shouldn't do that now.

Chrome version 125 contains patches for nine security vulnerabilities. Of particular concern is the vulnerability labeled CVE-2024-4947, which refers to "Type Confusion in V8". This bug happens when the code doesn't check the object passed to it, which allows attackers to execute their own code on your device.

What makes this vulnerability particularly dangerous is the fact that it is a "zero-day" flaw, meaning that it has already been actively exploited. This means that attackers are already aware of this vulnerability and have used it for hacking. When you come across a tag like this, you should update your apps immediately.

In addition to this, Google identified two other "zero-day" vulnerabilities affecting Chrome this month. The first, CVE-2024-4671, was patched on May 9, while the second, CVE-2024-4761, was patched on May 13. Both vulnerabilities allow attackers to access data they should not otherwise have access to.

The US Cyber Security and Infrastructure Agency (CISA) has added all three vulnerabilities to its catalog of known exploited vulnerabilities. Federal agencies have until June 10 to update their Chrome browsers, but you can do it now, LifeHacker reports.
