Assigner: kernel.org

Description
In the Linux kernel, the following vulnerability has been resolved: soc: qcom: smsm: Fix refcount leak bugs in qcom_smsm_probe() There are two refcount leak bugs in qcom_smsm_probe(): (1) The 'local_node' is escaped out from for_each_child_of_node() as the break of iteration, we should call of_node_put() for it in error path or when it is not used anymore. (2) The 'node' is escaped out from for_each_available_child_of_node() as the 'goto', we should call of_node_put() for it in goto target.

Executive Summary

This vulnerability involves two reference count (refcount) leak bugs in the Linux kernel's qcom_smsm_probe() function. Specifically, certain nodes ('local_node' and 'node') are not properly released (via of_node_put()) when they are no longer needed or when an error occurs, leading to resource leaks.

Impact Analysis

The refcount leak bugs can cause resource leaks in the kernel, potentially leading to increased memory usage or instability over time if the leaked references accumulate.
