hw: cpu: Intel: Stale Data Read from legacy xAPIC vulnerability

Improper isolation of shared resources in some Intel(R) Processors may allow a privileged user to potentially enable information disclosure via local access.

Hardware debug modes and processor INIT setting that allow override of locks for some Intel(R) Processors in Intel(R) Boot Guard and Intel(R) TXT may allow an unauthenticated user to potentially enable escalation of privilege via physical access.

microcode: Out of bounds read for some Intel Atom processors

Out of bounds read under complex microarchitectural condition in memory subsystem for some Intel Atom(R) Processors may allow authenticated user to potentially enable information disclosure or cause denial of service via network access.

kernel: Intel firmware update for insufficient granularity of access control in out-of-band management in some Intel Atom and Intel Xeon Scalable Processors

Insufficient granularity of access control in out-of-band management in some Intel(R) Atom and Intel Xeon Scalable Processors may allow a privileged user to potentially enable escalation of privilege via adjacent network access.
