CVE-2025-3931

Local privilege escalation via unrestricted D-Bus dispatch

Published May 14, 2025 · Updated Nov 11, 2025

Local privilege escalation in Red Hat Yggdrasil before 0.4.7 allows local users to install arbitrary RPM packages through D-Bus. The com.redhat.Yggdrasil1 policy permits unprivileged callers to invoke Dispatch, which forwards attacker-controlled content to root-running workers. A low-privileged account and a root-running package-management worker are required; successful dispatch grants root-level package installation and data access.
