CVE-2025-6018 – Linux PAM pam-config Local Privilege Escalation

CVE ID : CVE-2025-6018

Published : July 23, 2025, 3:15 p.m. | 1 hour, 44 minutes ago

Description : A Local Privilege Escalation (LPE) vulnerability has been discovered in pam-config within Linux Pluggable Authentication Modules (PAM). This flaw allows an unprivileged local attacker (for example, a user logged in via SSH) to obtain the elevated privileges normally reserved for a physically present, “allow_active” user. The highest risk is that the attacker can then perform all allow_active yes Polkit actions, which are typically restricted to console users, potentially gaining unauthorized control over system configurations, services, or other sensitive operations.

Severity: 7.8 | HIGH
