Before, Google would share details of the threats as well as their solutions. But, with regard to the latest vulnerabilities discovered, the tech company is mum when it comes to explanations.

Google has restricted information about the cyberattacks to allow time for users to update their Chrome browsers before cybercriminals can take advantage of thee vulenrabilities.

“Access to bug details and links may be kept restricted until a majority of users are updated with a fix,” says Google in a blog posted last January 19.

According to Forbes, many of the vulnerabilities listes are ‘Use-After-Free’ (UAF). What happens is that these vulnerabilities are exploits created when a program does not clear the pointer to the memory after it is freed.

UAF exploits are very popular amongst Google hackers, as many of the previous threats have been pretty similar.

It was reported that Google experienced the record-breaking number attacks in 2021. And for this very reason, it is important to keep your Chrome browsers updated at all times to lower your threat risk.
