Google Wants to Make Linux Kernel Flaws Harder to Exploit
'Experimental mitigations' in a custom kernel could make life harder for hackers.
Google says it uses Linux in "almost everything" from Chromebooks to the cloud. Now it is increasing its rewards for security researchers who can spot flaws in the open-source operating system.
Since 2020, Google has run an open-source Kubernetes-based Capture-the-Flag (CTF) project called kCTF which allows researchers to connect to its Google Kubernetes Engine (GKE) instances, and try to hack them to capture a flag. Every 'flag' caught so far has been a container breakout through a Linux kernel vulnerability.
