The vulnerability is described as a Use-after-free (UAF) vulnerability in the Animation component.

UAF is a type of vulnerability that is the result of the incorrect use of dynamic memory during a program’s operation.

If, after freeing a memory location, a program does not clear the pointer to that memory, an attacker can use the error to manipulate the program.

Referencing memory after it has been freed can cause a program to crash, use unexpected values, or execute code.

In this case, when the vulnerability is exploited, this can lead to corruption of valid data and the execution of arbitrary code on affected systems.

As a result, a remote attacker can create a specially crafted web page, trick the victim into visiting it, trigger the UAF vulnerability and execute arbitrary code on the target system.

How to Protect Yourself

Update your chrome browser to version 98.0.4758.102as soon as possible
