5 Processor MMIO Stale Data Vulnerabilities are a class of memory-mapped I/O
12 stale data into core fill buffers where the data can subsequently be inferred
21 Propagators are operations that result in stale data being copied or moved from
22 one microarchitectural buffer or register to another. Processor MMIO Stale Data
23 Vulnerabilities are operations that may result in stale data being directly
