摘要
Embodiments for mitigating cache-based data security vulnerabilities in a computing environment are provided. Cache pollution due to speculative memory accesses within a speculative path is avoided by delaying data updates to a cache and memory subsystem until the speculative memory accesses are resolved. A speculative buffer is used to maintain the speculative memory accesses such that a state of the cache remains unchanged until the speculative memory accesses are committed.
