Incomplete cleanup of multi-core shared buffers for some Intel Processors

via local access (CVE-2022-21123).

Incomplete cleanup of microarchitectural fill buffers on some Intel
Processors may allow an authenticated user to potentially enable information
disclosure via local access (CVE-2022-21125).

Incomplete cleanup in specific special register read operations for some
Intel Processors may allow an authenticated user to potentially enable
information disclosure via local access (CVE-2022-21127, CVE-2022-21166).

For other upstream fixes, see the referenced changelogs.");
