Hackers have exploited up to 6 zero-day vulnerabilities on Chrome in 2021

Although 2021 is only half over, there have been 6 zero-day vulnerabilities on Google Chrome that were exploited by hackers before being patched. The newly patched vulnerability stems from a confusion about V8, open source and C++ WebAssembly and Google's JavaScript engine.

Only half of 2021 has passed, but hackers have exploited up to 6 serious zero-day vulnerabilities on Chrome

Here are 5 other Google Chrome zero-day vulnerabilities that were exploited by hackers this year:

• CVE-2021-21148 - February 4, 2021
• CVE-2021-21166 - March 2, 2021
• CVE-2021-21193 - March 12, 2021
• CVE-2021-21220 - April 13, 2021
• CVE-2021-21224 - April 20, 2021

According to information from experts, a group of hackers called Puzzlemarker is chaining Google Chrome's zero-day vulnerabilities to get out of the browser sandbox and install malware on Windows.

The researchers say that when combining both the Chrome and Windows vulnerabilities, hackers can get into the victim's system to install malware. Microsoft has also patched the CVE-2021-33742 vulnerability in the June Patch Tuesday patch.

As of now, it's not clear which Google vulnerability Puzzlemaker exploits. Security firm Kaspersky believes that hackers may have exploited the vulnerability CVE-2021-21224 but does not rule out the possibility that they use other vulnerabilities that Google has not discovered.
