2021 arXiv   pre-print
The highly publicized vulnerability uses speculative execution to learn victim secrets by changing cache state.  ...  We show that this problem is not easy to fix: Speculative interference converts timing changes to persistent cache-state changes, and timing is typically ignored by many cache-based defenses.  ...  of the frontend and the execution engine are not deallocated until the instruction becomes non-speculative.  ...
