Integrity: None
Availability: None

Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Local: The vulnerable component is not bound to the network stack and the attacker’s path is via read/write/execute capabilities. Either: the attacker exploits the vulnerability by accessing the target system locally (e.g., keyboard, console), or remotely (e.g., SSH); or the attacker relies on User Interaction by another person to perform actions required to exploit the vulnerability (e.g., tricking a legitimate user into opening a malicious document).
Attack Complexity: Low: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
Privileges Required: Low: The attacker is authorized with (i.e., requires) privileges that provide basic user capabilities that could normally affect only settings and files owned by a user. Alternatively, an attacker with Low privileges may have the ability to cause an impact only to non-sensitive resources.
User Interaction: None: The vulnerable system can be exploited without any interaction from any user.
Scope: Unchanged: An exploited vulnerability can only affect resources managed by the same security authority. In this case, the vulnerable component and the impacted component are either the same, or both are managed by the same security authority.
Confidentiality: High: There is total loss of confidentiality, resulting in all resources within the impacted component being divulged to the attacker. Alternatively, access to only some restricted information is obtained, but the disclosed information presents a direct, serious impact.
Integrity: None: There is no loss of integrity within the impacted component.
Availability: None: There is no impact to availability within the impacted component.

Detectable: no evidence on record.

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 2 Nov 2026.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponized: A Metasploit exploit module or Exploit-DB entry exists (Metasploit scanner modules do not count), or CISA SSVC or the CVSS exploit maturity reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

AI-suggested

Red Hat recommends restricting visibility of process command-line arguments by mounting /proc with the hidepid=2 option (e.g., 'mount -o remount,hidepid=2 /proc' or configuring '/etc/fstab' accordingly). This prevents unprivileged local users from reading other users' process arguments. Additionally, on shared hosts, avoid supplying passwords through Cockpit Machines VM create and install flows and prefer provisioning methods that do not pass passwords on the command line. Updated cockpit-machines packages that stop passing password material on the command line are being delivered; installing these updated packages once available resolves the issue.

Description

CVE-2026-92768 is a vulnerability in the cockpit-machines component of Red Hat Enterprise Linux 10 that allows local attackers to expose sensitive VM credentials, including plaintext passwords. This occurs because passwords are passed via command-line arguments during VM creation or installation, making them visible to other local users if process argument visibility is not restricted. Exploitation requires local access and a specific execution window. The vulnerability leads to information disclosure that could compromise VM access.

Impact

Successful exploitation allows local attackers to disclose sensitive VM credentials, including plaintext passwords, by inspecting process command-line arguments. This can lead to compromise of VM access. The attack requires local access and a specific execution window during VM creation or installation. There is no indication of remote exploitation or denial of service.

Summary

The vulnerability in cockpit-machines involves passing sensitive VM credentials, such as plaintext passwords, directly on the command line during VM creation or installation. Since process command-line arguments are visible to other local users on systems without restricted /proc visibility, a local attacker can read these arguments and obtain sensitive information. The flaw requires local access and a timing window during VM operations. Red Hat advises restricting process argument visibility by mounting /proc with the hidepid=2 option and avoiding passing passwords on the command line. Updated cockpit-machines packages that eliminate this behavior are being released to fix the issue.
