AV:L/AC:L/PR:L/UI:R/S:U/C:H/I:N/A:N
Local process inspection by an authenticated user (AV:L/PR:L), no complexity beyond timing (AC:L), dependent on an admin running an install (UI:R); disclosure-only, so C:H, I:N, A:N.

Lifecycle Timeline
1DescriptionCVE.org
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.
AnalysisAI
Local information disclosure in cockpit-machines on Red Hat Enterprise Linux 9 and 10 allows an authenticated local attacker who can enumerate other users' process arguments to read guest VM installation credentials such as rootPassword and userPassword. The credentials are passed by install_machine.py as a JSON command-line argument during VM creation, so exposure is limited to the window while an administrator's installation workflow is running and depends on the host's process-visibility policy (e.g. …

| Exploitation | Requires local access to the RHEL host as a user able to enumerate other users' process arguments (i.e. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | This is a genuine but modest-severity local information-disclosure issue, not a high-urgency remote flaw. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | No vendor-released patch was identified at the time of analysis (CVSS vector is CVSS:3.1/AV:L/AC:L/PR:L/UI:R/S:U/C:H/I:N/A:N, and the SSVC decision point is Exploitation:poc), so monitor the Red Hat CVE page https://access.redhat.com/security/cve/CVE-2026-92747 and Bugzilla 2469260 for an updated cockpit-machines package and apply it as soon as it is published. … Detailed patch versions, workarounds, and compensating controls in full report. |
