Description

CVE-2026-92768 is a vulnerability in the cockpit-machines component that allows a local attacker to expose sensitive Virtual Machine credentials, including plaintext passwords, by inspecting process command-line arguments during VM creation or installation. This occurs because cockpit-machines passes password values directly on the command line, making them visible to other local users on systems without process argument restrictions. The vulnerability leads to information disclosure that could compromise VM access. A security update addressing this issue is available for Red Hat Enterprise Linux 9 and related variants.
