Techniques & Countermeasures

  • CWE-1421•Exposure of Sensitive Information in Shared Microarchitectural Structures during Transient Execution

    A processor event may allow transient operations to access architecturally restricted data (for example, in another address space) in a shared microarchitectural structure (for example, a CPU cache), potentially exposing the data over a covert channel.
