The remote Debian 10 host has a package installed that is affected by multiple vulnerabilities as referenced in the dla-3537 advisory.
Information exposure through microarchitectural state after transient execution in certain vector execution units for some Intel® Processors may allow an authenticated user to potentially enable information disclosure via local access. (CVE-2022-40982)
Unauthorized error injection in Intel® SGX or Intel® TDX for some Intel® Xeon® Processors may allow a privileged user to potentially enable escalation of privilege via local access. (CVE-2022-41804)
Improper access control in some 3rd Generation Intel® Xeon® 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.
