Technical details
A race condition (CWE-362) exists in Microsoft .NET Framework due to improper synchronization when multiple threads access a shared resource. The vulnerability is reachable over the network and does not require user interaction or administrative privileges, though the attack complexity is rated as high. Successful exploitation allows an attacker to trigger a denial-of-service (DoS) state. Affected versions include .NET Framework 3.5, 4.7.2, 4.8, and 4.8.1 across various Windows and Windows Server platforms. Security updates are available via the Microsoft Security Response Center (MSRC).
