The vulnerability (CVE-2023-2136) was caused by a type misunderstanding flaw in the Blink engine’s processing of JavaScript objects, according to Google’s security alert. An attacker could exploit the flaw by utilising a specially constructed web page to mislead the browser into accessing an object in a way that it was not intended to be accessed. This could cause memory corruption and allow the attacker to run code on the victim’s PC.

Google has not released any details about the attackers exploiting this vulnerability, but it has classified the bug as being “high severity”. Google has also released a patch for the vulnerability in the latest version of Chrome, which users should update to as soon as possible. In addition, Google has also credited an external researcher for reporting the vulnerability, highlighting the importance of a coordinated effort between security researchers and software vendors in detecting and addressing security vulnerabilities.
This is Google’s second zero-day vulnerability fix in 2023, demonstrating that attackers’ attacks are becoming more sophisticated. It is also a reminder of the necessity of keeping software up to current with the latest security updates, as these patches are frequently meant to repair vulnerabilities that criminal actors could exploit.
