Background

The ARM versatile package is a kernel module that provides support for the ARM Versatile platform. This platform is commonly used for development and testing purposes. The dcscb_init function is responsible for initializing the Versatile Dynamic Clock and System Controller Block (DCSCB) driver. However, there is a missing of_node_put call in the dcscb_init function, which can lead to a memory leak.

Vulnerability Detail

This vulnerability can be exploited by an attacker to exhaust system memory resources, potentially leading to a denial of service (DoS) condition. By repeatedly triggering this vulnerability, an attacker could cause the system to become unresponsive or crash.
