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-2024:1139-1 advisory.
Protection mechanism failure in some 3rd and 4th Generation Intel® Xeon® Processors when using Intel® SGX or Intel® TDX may allow a privileged user to potentially enable escalation of privilege via local access. (CVE-2023-22655)
Information exposure through microarchitectural state after transient execution from some register files for some Intel® Atom® Processors may allow an authenticated user to potentially enable information disclosure via local access. (CVE-2023-28746)
Non-transparent sharing of return predictor targets between contexts in some Intel® Processors may allow an authorized user to potentially enable information disclosure via local access. (CVE-2023-38575)
Protection mechanism failure of bus lock regulator for some Intel® Processors may allow an unauthenticated user to potentially enable denial of service via network access. (CVE-2023-39368)
Incorrect calculation in microcode keying mechanism for some Intel® Xeon® D Processors with Intel® SGX may allow a privileged user to potentially enable information disclosure via local access.
(CVE-2023-43490)
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
