Recommended response

Check inventory. Check lockfiles and deployed manifests for Red Hat/cockpit-machines.
Review the reported fix. Source-reported workaround: Restrict visibility of process command-line arguments to other local users by mounting /proc with the hidepid=2 option, for example by remounting /proc with 'mount -o remount,hidepid=2 /proc' or configuring 'proc /proc proc defaults,hidepid=2 0 0' in /etc/fstab. This prevents unprivileged local users from reading other users' process arguments. Additionally, on shared hosts where other local users can inspect process arguments, avoid supplying root or user passwords through the Cockpit Machines VM create and install flows, and prefer provisioning methods that do not pass passwords on the command line. Updated cockpit-machines packages that stop passing password material on the command line are being delivered for affected streams; installing the updated package once it is available for your stream resolves this issue.

Sources and claim methodology

Upstream source description

A flaw was found in cockpit-machines. This vulnerability allows a local attacker to expose sensitive Virtual Machine (VM) credentials, including plaintext passwords, by inspecting process command-line arguments during VM creation or installation. The cockpit-machines component passes password values directly on the command line, making them visible to other local users on systems where process arguments are not restricted. Successful exploitation leads to information disclosure, potentially compromising VM access.
