How to check if kernel is properly updated/patched?
I have received an email from Digital Ocean to update the OS to mitigate the industry-wide security vulnerabilities known as Meltdown and Spectre
Quote from email:
To simplify the act of patching, we have recently updated Droplets to utilize a GrubLoader. On certain legacy Droplets, this may cause issues if the kernel is not upgraded.
This is the link that I am referred to about the upgrade:
I am running CentOS 6, I have executed the following
yum update yum update kernel
When I do uname -r I still get:
But when I do yum install kernel I get:
Package kernel-2.6.32-696.20.1.el6.x86_64 already installed and latest version
Does that mean the kernel is not updated accordingly?
