Techniques & Countermeasures

  • CWE-1342•Information Exposure through Microarchitectural State after Transient Execution

    The processor does not properly clear microarchitectural state after incorrect microcode assists or speculative execution, resulting in transient execution.

  • CWE-203•Observable Discrepancy

    The product behaves differently or sends different responses under different circumstances in a way that is observable to an unauthorized actor.
