Problem Description:
On some Intel processors utilizing speculative execution
a local process may be able to infer stale information from
microarchitectural buffers to obtain a memory disclosure.
Impact:
An attacker may be able to read secret data from the
kernel or from a process when executing untrusted code (for
example, in a web browser).
