What it is

Exposure of sensitive information caused by incorrect data forwarding during transient execution for some Intel(R) Processors within Ring 0: Hypervisor and Kernel may allow information disclosure. System software adversary with a privileged user combined with a high complexity attack may enable data exposure. This result may potentially occur via local access when attack requirements are not present without special internal knowledge and requires no user interaction. The potential vulnerability may impact the confidentiality (none), integrity (none) and availability (none) of the vulnerable system, resulting in subsequent system confidentiality (high), integrity (none) and availability (none) impacts.
