    I understand that you have a RHEL 9.3 VM in Azure and want to understand which updates are needed to make sure that you are not impacted by RHEL CVE-2023-1998.

    Information about this vulnerability and the patches needed are included in the link I provided. RHEL 9.3 has a newer kernel version (5.14.0-362.8.1) that is already patched for CVE-2023-1998. This vulnerability was fixed in kernel version 5.14.0-284.25.1. Therefore, any kernel version higher than that should be safe from this vulnerability. You can check your kernel version by running the command uname -r in the terminal.

    Microsoft Azure also has deployed mitigation across all of our servers. You can read more about this here: Guidance for mitigating silicon based micro-architectural and speculative execution side-channel vulnerabilities.

    Hope this answers your questions. Let me know if you have any more questions or concerns.
