Technical description

Garuda Linux performs an insecure user creation and authentication that allows any user to impersonate the created account. By creating users from the 'Garuda settings manager', an insecure procedure is performed that keeps the created user without an assigned password during some seconds. This could allow a potential attacker to exploit this vulnerability in order to authenticate without knowing the password.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
