CVE-2022-50119

Service interruption via rpmsg reference leak

Published Jun 18, 2025 · Updated May 11, 2026

A reference-count leak in the Linux kernel rpmsg subsystem 5.19 allows local users to exhaust kernel resources and interrupt service. The rpmsg_register_device_override function returns after driver_set_override fails without calling put_device on vch, leaving the device reference held. Triggering requires local low-privilege access and an rpmsg device whose override operation fails; the reported consequence is limited to availability.
