Language:

Synopsis

The remote Amazon Linux 2 host is missing a security update.

Description

The version of microcode_ctl installed on the remote host is prior to 2.1-47. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2024-2631 advisory.

 Insufficient control flow management for some Intel(R) Xeon Processors may allow an authenticated user to potentially enable denial of service via local access. (CVE-2024-22374)

Tenable has extracted the preceding description block directly from the tested product security advisory.

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

Solution

Run 'yum update microcode_ctl' to update your system.
