Recommended response

Check inventory. Check lockfiles and deployed manifests for Red Hat/cockpit-machines.
Review the reported fix. Source-reported workaround: A workaround is available for this issue. Until a fixed package is installed, avoid validating RHSM offline tokens through the Cockpit Machines "Download an OS" / RHEL image download flow on multi-user hosts where untrusted local users can inspect process metadata. As a system-level mitigation, restrict /proc visibility so unprivileged users cannot read other users' process command lines, for example by remounting /proc with the hidepid=2 mount option; this blocks cross-user observation of the helper process arguments that contain the offline token while the validation flow is running. Fixed packages are being released for the affected streams, and updating to a fixed cockpit-machines package once available for your stream resolves the issue.

Sources and claim methodology

Upstream source description

A flaw was found in cockpit-machines. This vulnerability allows a local attacker with the ability to inspect process metadata to disclose a sensitive Red Hat Subscription Management (RHSM) offline token. The token is exposed when it is passed as a command-line argument to a helper script during the token validation process. Successful exploitation could lead to the compromise of confidentiality, as the exposed token can be used to request access tokens.
