Last week, a critical vulnerability identified as CVE-2022-0185 was disclosed, affecting Linux kernel versions 5.1 to 5.16.1. The security vulnerability is an integer underflow in the Filesystem Context module that allows a local attacker to run arbitrary code in the context of the kernel, thus leading to privilege escalation, container environment escape, or denial of service.

Let’s face it – Kubernetes can (and is) oftentimes very complex. This means that you’re bound to make a cluster configuration mistake along the way – apart from it impacting your cluster’s performance and security, it can also heavily affect your ability to enforce visibility and troubleshooting. There is, however, a light at the end of the tunnel.

Central processing units (CPUs) can be compared to the human brain in that their unique architecture allows them to solve mathematical equations in different ways. x86 is the dominant architecture used in cloud computing at the time of this writing; however, it is worth noting that this architecture is not efficient for every scenario, and its proprietary nature is causing an industry shift toward ARM.
