Oracle Linux: CVE-2020-0548: ELSA-2020-2431: microcode_ctl security, bug fix and enhancement update (MODERATE) (Multiple Advisories)

Cleanup errors in some Intel(R) Processors may allow an authenticated user to potentially enable information disclosure via local access.
A flaw was found in Intel processors where a local attacker is able to gain information about registers used for vector calculations by observing register states from other processes running on the system. This results in a race condition where store buffers, which were not cleared, could be read by another process or a CPU sibling. The highest threat from this vulnerability is data confidentiality where an attacker could read arbitrary data as it passes through the processor.
