Description

The remote Oracle Linux 7 host has a package installed that is affected by multiple vulnerabilities as referenced in the ELSA-2020-5923 advisory.

 - Insufficient access control in the Linux kernel driver for some Intel(R) Processors may allow an authenticated user to potentially enable information disclosure via local access. (CVE-2020-8694)

 - Observable discrepancy in the RAPL interface for some Intel(R) Processors may allow a privileged user to potentially enable information disclosure via local access. (CVE-2020-8695)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
