    CVE(s):
    CVE-2023-20592
    Improper or unexpected behavior of the INVD instruction in some AMD CPUs may allow an attacker with a
    malicious hypervisor to affect cache line write-back behavior of the CPU leading to a potential loss of
    guest virtual machine (VM) memory integrity.
    CVE-2023-31315
    Improper validation in a model specific register (MSR) could allow a malicious program with ring0 access
    to modify SMM configuration while SMI lock is enabled, potentially leading to arbitrary code execution.

Tenable has extracted the preceding description block directly from the MiracleLinux security advisory.

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