Node.js pushes out immediate fixes for the flaw​

This week Node.js has pushed out fixes for high severity, use-after-free vulnerability, tracked as CVE-2021-22930.

Use-after-free vulnerabilities occur when a program tries to access a resource at a memory address that has been previously freed and no longer holds the resource.

This can lead to data corruption, or unexpected behaviors such as application crashes, or even remote code execution (RCE) in some cases.
