Doc Text:
A potential domain bypass transient execution vulnerability was discovered on some Intel Atom® processors that uses a microarchitectural incidental channel. Currently this channel can reveal supervisor data in the L1 cache and the contents of recent stores. As a consequence, this issue may allow an authenticated user to potentially enable information disclosure via local access.
