AI-suggested

Red Hat has released an official security update for Red Hat Enterprise Linux 9 that addresses this vulnerability. Applying the update as described in Red Hat advisory RHSA-2026:86970 will remediate the issue. Users should follow the instructions in the advisory to update cockpit-machines to the fixed version. No additional mitigation is required once the update is applied.

Description

A vulnerability in cockpit-machines allows a local attacker who can inspect running processes to expose sensitive guest VM credentials, such as root and user passwords. This occurs because the install_machine.py script passes these credentials as JSON command-line arguments during VM creation or installation, making them visible in process listings during the active installation workflow. The exposure is limited to the installation period and depends on host process visibility policies. Red Hat has issued a security update for Red Hat Enterprise Linux 9 to address this issue.
