CVE-2026-92768— Cockpit-machines: cockpit-machines: sensitive data exposure via command-line arguments

Quick assessment

Affected

Red Hat Red Hat Enterprise Linux 10

Exploitation

No confirmed in-the-wild exploitation; assess based on exposure

Recommended action

Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

在 cockpit-machines 中发现了一个漏洞。该漏洞允许本地攻击者在虚拟机（VM）创建或安装过程中，通过检查进程的命令行参数来暴露敏感的虚拟机凭据，包括明文密码。cockpit-machines 组件直接将密码值传递到命令行中，因此在未对进程参数进行限制的系统上，这些密码对其他本地用户可见。成功利用此漏洞会导致信息泄露，进而可能危及对虚拟机的访问权限。

Vulnerability Title

Cockpit-machines: cockpit-machines: sensitive data exposure via command-line arguments

Source: CVE Program / CVE List V5

Vulnerability Description

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.
