CVE-2026-37526
Description
AGL app-framework-binder (afb-daemon) through v19.90.0 allows any local process to execute privileged supervision commands (Exit, Do, Sclose, Config, Trace, Debug, Token, slist) without authentication via the abstract Unix socket @urn:AGL:afs:supervision:socket. The on_supervision_call function in src/afb-supervision.c dispatches all 8 commands without any credential verification. The abstract socket has no DAC protection, as acknowledged in the official CAUTION comment in src/afs-supervision.h. This allows a low-privileged local process to kill the daemon (DoS via Exit command), execute arbitrary API calls (via Do command), close arbitrary user sessions (via Sclose command), or leak the entire global configuration (via Config command). The vulnerability was introduced in commit b8c9d5de384efcfa53ebdb3f0053d7b3723777e1 on 2017-06-29.
