The Chrome Stable channel has been updated to 119.0.6045 for both Linux and Mac and 119.0.6045.199/.200 for Windows. Although the update hasn’t been rolled out for every user, Google has confirmed it will happen over the coming days/weeks.

It is the final vulnerability, listed above, that is the zero-day exploit. It’s interesting to know that this vulnerability is listed as High and not Critical. Even so, any bug listed as High should be considered a must-patch. Other than saying this vulnerability exists in the wild, Google has been a bit hush-hush about it.
