Why Security in Kubernetes Isn't the Same as in Linux: Part 2

Security for Kubernetes might not be quite the same as what you're used to. In our previous article, we covered why security is so important in both Linux on-premises servers and cloud Kubernetes clusters. We also talked about 3 major aspects of Linux server security — processes, network, and fil...

DEBIAN-CVE-2021-43816

containerd is an open source container runtime. On installations using SELinux, such as EL8 CentOS, RHEL, Fedora, or SUSE MicroOS, with containerd since v1.5.0-beta.0 as the backing container runtime interface CRI, an unprivileged pod scheduled to the node may bind mount, via hostPath volume, any...

devices resource list treated as a blacklist by default

Impact Contrary to the OCI runtime specification, runc's implementation of the linux.resources.devices list was a black-list by default. This means that users who created their own config.json objects and didn't prefix a deny-all rule "allow": false, "permissions": "rwm" or equivalent were not...
