MGASA-2022-0064

Updated microcodes for Intel processors, fixing various functional issues, and at least the following security issues:

Insufficient control flow management in some Intel(R) Processors may allow an authenticated user to potentially enable a denial of service via local access (CVE-2021-0127 / SA-00532).

Improper initialization of shared resources in some Intel(R) Processors may allow an authenticated user to potentially enable information disclosure via local access (CVE-2021-0145 / SA-00561).

Hardware allows activation of test or debug logic at runtime for some Intel(R) processors which may allow an unauthenticated user to potentially enable escalation of privilege via physical access (CVE-2021-0146 / SA-00528).

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 (CVE-2021-33120 / SA-00589)
