CVE-2025-23222Public exploit

Local privilege escalation via root-identity forwarding

Published Jan 24, 2025 · Updated Feb 12, 2025

Authentication bypass in Deepin dde-api-proxy 1.0.19 and earlier allows local users to execute privileged D-Bus methods. The root-running handleMessage() path forwards legacy-interface calls over its own connection, so backend services identify the proxy as UID 0 instead of the caller. Any local account able to reach the system bus can invoke protected operations, including changing boot settings or adding its account to the root group.
