摘要
Typical out-of-order machines can be exploited by security vulnerabilities, such as Meltdown and Spectre, that enable data leakage during misspeculation events. A method of preventing such information leakage includes storing information regarding multiple states of an out-of-order machine to a reorder buffer. This information includes the state of instructions, as well as an indication of data moved to a cache in the transition between states. In response to detecting a misspeculation event at a later state, access to at least a portion of the cache storing the data can be prevented.
