What is CVE-2022-0851?
CVE-2022-0851 is a medium-severity vulnerability in Redhat Enterprise Linux, published on 29 Aug 2022. It can only be exploited from the same machine or local network, with no action from the victim.
Official description
There is a flaw in convert2rhel. When the --activationkey option is used with convert2rhel, the activation key is subsequently passed to subscription-manager via the command line, which could allow unauthorized users locally on the machine to view the activation key via the process command line via e.g. htop or ps. The specific impact varies upon the subscription, but generally this would allow an attacker to register systems purchased by the victim until discovered; a form of fraud. This could occur regardless of how the activation key is supplied to convert2rhel because it involves how convert2rhel provides it to subscription-manager.
