Denial of Service via Ring 3 Race Condition in 3rd Gen Intel Xeon Scalable Processors

Hardware logic contains race conditions for some 3rd Gen Intel(R) Xeon(R) Scalable Processors within Ring 3: unprivileged software may allow a denial of service. Unprivileged software adversary with an authenticated user combined with a high complexity attack may enable denial of service. This result may potentially occur via local access when attack requirements are not present with special internal knowledge and requires no user interaction. The potential vulnerability may impact the confidentiality (none), integrity (none) and availability (high) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (high) impacts.
