Synopsis

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

Description

The version of kernel installed on the remote host is prior to 5.4.254-169.358. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2KERNEL-5.4-2025-116 advisory.

 A division-by-zero error on some AMD processors can potentially return speculative data resulting in loss of confidentiality. (CVE-2023-20588)

 scsi: core: Fix possible memory leak if device_add() fails (CVE-2023-53174)

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