An update correcting the various vulnerabilities of Chrome 91 is already available.
Several security flaws have been discovered in Chrome 91, the latest version of Google’s web browser, available since the end of May. The PC and mobile versions of Chrome are affected by these vulnerabilities, some of which are qualified as critical. Several of them are said to be actively exploited by hackers. That is why Google advises users to update their web browser.
Due to the active exploitation of several flaws, the Mountain View firm will not share details regarding the vulnerabilities discovered in version 91 of Chrome until a majority of users have installed the patch, namely version 91.0.4472.101. A choice which is not surprising and which aims to avoid making the work easier for hackers who might want to exploit these flaws in turn.
This update is being rolled out to users. You can therefore install it now on Windows, Linux and Android.
For the PC version, go to Chrome and go to the browser settings by clicking on the three small dots, at the top right. Then select Help, then “About Google Chrome”. You should be redirected to a new page. If you are offered update 91.0.4472.101, simply install it. If not, you will have to force the search.
On Android, open the Google Play Store and select your photo. Then tap on “My games & apps” and tap on “Update” in front of Google Chrome.
In the event that no update is offered, be patient, it should not be long. Google is indeed rolling out the patch to its users.
