Amazon Linux 2 : kernel (ALASKERNEL-5.15-2022-010)

medium Nessus Plugin ID 167237

Language:

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 5.15.75-48.135. It is, therefore, affected by a vulnerability as referenced in the ALAS2KERNEL-5.15-2022-010 advisory.

 - drivers/scsi/stex.c in the Linux kernel through 5.19.9 allows local users to obtain sensitive information from kernel memory because stex_queuecommand_lck lacks a memset for the PASSTHRU_CMD case.
 (CVE-2022-40768)

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 kernel' to update your system.
