Processor optimization removal or modification of security-critical code for some Intel(R) Processors may allow an authenticated user to potentially enable information disclosure via local access.

The remote CentOS Linux 9 host has a package installed that is affected by multiple vulnerabilities as referenced in the microcode_ctl-20220809-1.el9 build changelog.

  - 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)

  - 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)

  - 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)

  - Sensitive information accessible by physical probing of JTAG interface for some Intel(R) Processors with     SGX may allow an unprivileged user to potentially enable information disclosure via physical access.
