The remote SUSE Linux SLED15 / SLED_SAP15 / SLES15 / SLES_SAP15 / openSUSE 15 host has a package installed that is affected by multiple vulnerabilities as referenced in the SUSE-SU-2024:1771-1 advisory.

Intel CPU Microcode was updated to the 20240514 release (bsc#1224277)

- CVE-2023-45733: Fixed a potential security vulnerability in some       Intel? Processors that may have allowed information disclosure.
- CVE-2023-46103: Fixed a potential security vulnerability in Intel?       Core Ultra Processors that may have allowed denial of service.
- CVE-2023-45745,CVE-2023-47855: Fixed a potential security       vulnerabilities in some Intel? Trust Domain Extensions (TDX) module       software that may have allowed escalation of privilege.

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

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