TL;DR

Affected versions of the Microsoft.VisualStudio.Threading library are vulnerable to a race condition due to the lack of guaranteed ordering when reading this.joinableTask in the lock-free section of the logic. Under certain race conditions, AsyncLazy may wait on the inner task instead of the joinable task when two threads access this code simultaneously, potentially causing the program to hang and leading to a denial of service (DoS).
