AI description

Automated description summarized from trusted sources.

CVE-2025-66005 is a vulnerability found in InputPlumber, a Linux utility designed to combine input devices into virtual ones, often utilized in Linux gaming environments like SteamOS. This flaw stems from a complete lack of authorization within the InputManager D-Bus interface in versions prior to v0.63.0. This absence of proper authorization allows any local user on the system to access privileged D-Bus methods without authentication. Such access can be exploited to perform unauthorized file existence tests, leak sensitive information from restricted files (like `/root/.bash_history`), and trigger memory exhaustion, potentially leading to denial-of-service conditions.

Description: Lack of authorization of the InputManager D-Bus interface in InputPlumber versions before v0.63.0 can lead to local Denial-of-Service, information leak or even privilege escalation in the context of the currently active user session.
