Amazon Linux 2 : linux-firmware (ALAS-2024-2626)

high Nessus Plugin ID 206020

Language:

Synopsis

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

Description

The version of linux-firmware installed on the remote host is prior to 20200421-82.git78c0348. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2024-2626 advisory.

 Improper validation in a model specific register (MSR) could allow a malicious program with ring0 access to modify SMM configuration while SMI lock is enabled, potentially leading to arbitrary code execution.
 (CVE-2023-31315)

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 linux-firmware' to update your system.
