Google recently announced via a blog post that a high-security threat has been confirmed on Chrome, which affects Windows users, macOS and Linux. The technology company stated that Chrome witnessed its 11th ‘zero day’ exploit of the year pertaining to CVE-2021-37973.
According to Forbes, a zero-day classification means hackers have been able to exploit the flaw before Google could release a fix, which makes it significantly more dangerous than most security flaws. Google confirmed this saying it “is aware that an exploit for CVE-2021-37973 exists in the wild”.
This is a zero-day exploit and what it refers to is the fact that cybercriminals were able to exploit it before Google found out and before it could release a patch for Google Chrome to stop them. Also, considering that there are as many as 2.65 bn Google Chrome users, the scale of the problem can well be imagined.
Over 2 billion Google Chrome users have been warned to update their browsers after a critical hack was discovered. This attack puts almost all Google Chrome users under threat of being hacked.
Google revealed threat ranking on its blog, "High CVE-2021-37973: Use after free in Portals. Reported by Clement Lecigne from Google TAG, with technical assistance from Sergei Glazunov and Mark Brand from Google Project Zero on 2021-09-21."
It also added a feel-good part, "We would also like to thank all security researchers that worked with us during the development cycle to prevent security bugs from ever reaching the stable channel."
All users need to upgrade to Google Chrome. The sooner they do so, the better.
