CVE-2026-58739

Local privilege escalation via confused deputy

Published Sep 15, 2026 · Updated Sep 15, 2026

Privilege escalation in the Google Android kernel allows local users with System execution privileges to gain elevated access. The platform_msg_handler_init function in default_msg_handlers.c acts as a confused deputy, but Google has not disclosed the delegated operation or input path. Exploitation requires local code already running with System execution privileges and no user interaction; the bounded result is additional local privilege.
