CVE-2026-37526

Local privilege escalation via unauthenticated supervision commands

Published May 1, 2026 · Updated May 1, 2026

Improper access control in AGL app-framework-binder through 19.90.0 allows local users to execute privileged supervision commands. The on_supervision_call function dispatches eight commands from the abstract Unix supervision socket without authenticating the caller, while that socket provides no DAC protection. Low-privileged local access permits daemon termination, arbitrary API calls, session closure, and disclosure of global configuration.
