Google has pushed out an emergency Chrome update to fix yet another pair of zero days - the second pair this month - that are being exploited in the wild.
On Thursday evening, the web Goliath released the Chrome 94.0.4606.71 stable channel release for Windows, Mac and Linux to fix the two zero-days, which were included in an update with a total of four security fixes.
"Google is aware the exploits for CVE-2021-37975 and CVE-2021-37976 exist in the wild," Google disclosed with the release of the browser fixes.
Just as it did with the pair of zero days that were being exploited in the wild earlier this month, Google is keeping technical details close to the vest, at least until most users have had a chance to plug in the update.
The earlier pair of zero days Google addressed this month in a Sept. 13 update, CVE-2021-30632 and CVE-2021-30633, were likewise being actively exploited in the wild.
If an attacker has managed to get the memory address, the actor "Can gain access to the free memory list, and insert malicious software into free memory," Nayyar continued.
