"The remote NewStart CGSL host, running version MAIN 7.02, has microcode_ctl packages installed that are affected by
multiple vulnerabilities:

  - Information exposure through microarchitectural state after transient execution in certain vector
    execution units for some Intel(R) Processors may allow an authenticated user to potentially enable
    information disclosure via local access. (CVE-2022-40982)

  - Improper access control in some 3rd Generation Intel(R) Xeon(R) Scalable processors may allow a privileged
    user to potentially enable information disclosure via local access. (CVE-2023-23908)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
number.");
