Release : 10.0

Component : API GATEWAY


The kernel vulnerabilities are addressed in the August monthly platform patch. However, after the patch is installed, the Gateway is supposed to pick up kernel-3.10.0-1127.18.2.el7.x86_64.rpm but is still stuck with kernel-3.10.0-1062.12.1.el7.x86_64.


To make sure the Gateway is able to pick up the latest kernel a temporary fix has been created, see the attached

Once the script is executed, all the missing kernel entries will be added to /boot/grub2/grub.cfg file from /etc/grub2.cfg - this is the actual file that gets updated whenever we install new kernel rpm's. A soft link has also been added to /etc/grub2.cfg so that it will take care of future kernel updates.

This will be addressed in the September 2020 platform patch.

Steps to execute the script:

1. copy the script to Azure VM

2. add the execution permissions: chmod 755 <script path>/

3. execute the shell script
