CVE-2026-92747
Description
A flaw was found in cockpit-machines. This vulnerability allows a local attacker with the ability to inspect running processes to expose sensitive guest virtual machine (VM) credentials, such as rootPassword and userPassword. This occurs when the install_machine.py script passes these credentials as a JSON command-line argument during VM creation or installation. The exposure is limited to the period when the installation workflow is active and depends on host process-visibility policies.
Statement
This flaw in cockpit-machines can lead to sensitive data exposure of guest VM credentials. When creating or installing a VM with password fields populated, install_machine.py passes these credentials as a JSON command-line argument. This makes them visible to other local users on the host who can inspect running processes, but only while the installation workflow is active and if host process-visibility policies permit.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
The following CVSS metrics and score provided are preliminary and subject to review.
