high Nessus Plugin ID 207917

Synopsis

The remote CentOS host is missing one or more security updates for microcode_ctl.

Description

The remote CentOS Linux 9 host has a package installed that is affected by multiple vulnerabilities as referenced in the microcode_ctl-20240910-1.el9 build changelog.

 - Observable discrepancy in RAPL interface for some Intel(R) Processors may allow a privileged user to potentially enable information disclosure via local access. (CVE-2024-23984)

 - Incorrect behavior order in transition between executive monitor and SMI transfer monitor (STM) in some Intel(R) Processor may allow a privileged user to potentially enable escalation of privilege via local access. (CVE-2024-24853)

 - Improper finite state machines (FSMs) in hardware logic in some Intel(R) Processors may allow an privileged user to potentially enable a denial of service via local access. (CVE-2024-24968)

 - Protection mechanism failure in some 3rd, 4th, and 5th Generation Intel(R) Xeon(R) Processors may allow a privileged user to potentially enable escalation of privilege via local access. (CVE-2024-24980)

 - Mirrored regions with different values in 3rd Generation Intel(R) Xeon(R) Scalable Processors may allow a privileged user to potentially enable denial of service via local access. (CVE-2024-25939)

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

Solution
