Synopsis

The remote Fedora host is missing one or more security updates.

Description

The remote Fedora 37 host has a package installed that is affected by multiple vulnerabilities as referenced in the FEDORA-2023-10d34be85a advisory.

 - Information exposure through microarchitectural state after transient execution in certain vector execution units for some Intel(R) Processors may allow an authenticated user to potentially enable information disclosure via local access. (CVE-2022-40982)

 - Improper access control in some 3rd Generation Intel(R) Xeon(R) Scalable processors may allow a privileged user to potentially enable information disclosure via local access. (CVE-2023-23908)

 - Unauthorized error injection in Intel(R) SGX or Intel(R) TDX for some Intel(R) Xeon(R) Processors may allow a privileged user to potentially enable escalation of privilege via local access. (CVE-2022-41804)

 - Insufficient granularity of access control in out-of-band management in some Intel(R) Atom and Intel Xeon Scalable Processors may allow a privileged user to potentially enable escalation of privilege via adjacent network access. (CVE-2022-21216)

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

Solution

Update the affected 2:microcode_ctl package.
