AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N
Local authenticated user (AV:L/PR:L); AC:H because the plaintext password is only visible in process args during the transient VM-creation window and requires a timing race; C:H for credential disclosure, no I/A impact.

Lifecycle Timeline
2DescriptionCVE.org
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.
AnalysisAI
Local information disclosure in cockpit-machines on Red Hat Enterprise Linux 9 and 10 allows an authenticated local user to read plaintext VM credentials - including passwords - that the component passes directly on process command-line arguments during VM creation or installation. Exploitation is timing-dependent: the secret is only readable while a provisioning operation is in flight, and it also requires that /proc process arguments remain visible to other users (i.e., the host is not hardened with a hidepid-style mount option), so risk concentrates on multi-user or shared virtualization hosts. …

Vulnerability AssessmentAI
| Exploitation | Requires an already-authenticated local user account on a host running the cockpit-machines package (RHEL 9 or 10), and exploitation only succeeds during the transient window when a VM is being created or installed with a password supplied through Cockpit - the credential is exposed solely while that provisioning process is running. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | This is a genuine but low-to-moderate severity local information-disclosure flaw, correctly rated Medium (CVSS 5.5, vector CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N). … 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 has been identified at time of analysis, so remediate by reducing exposure until an updated cockpit-machines package ships; confirm status and any errata on the Red Hat CVE page (https://access.redhat.com/security/cve/CVE-2026-92768) and the Bugzilla record (https://bugzilla.redhat.com/show_bug.cgi?id=2469258). … Detailed patch versions, workarounds, and compensating controls in full report. |
