Linux Kernel rpmsg Refcount Leak Vulnerability

A refcount leak vulnerability has been identified in the Linux kernel's rpmsg subsystem. The issue arises in the function rpmsg_register_device_override(), which fails to properly release a reference count when driver_set_override() encounters an error. This oversight could potentially lead to memory management issues.

Impact

Exploitation of this vulnerability could result in a refcount leak, causing memory management problems that might be exploited for arbitrary code execution or to cause a denial-of-service condition.
