escalation (CVE-2022-2588)

* Incomplete cleanup of multi-core shared buffers (aka SBDR)
(CVE-2022-21123)

* Incomplete cleanup of microarchitectural fill buffers (aka SBDS)
(CVE-2022-21125)

* Incomplete cleanup in specific special register write operations (aka
DRPW) (CVE-2022-21166)

For more details about the security issue(s), including the impact, a CVSS
score, acknowledgments, and other related information, refer to the CVE
page(s) listed in the References section.

4. Solution:
