Description
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.

AI Powered Q&A
Can you explain this vulnerability to me?
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.
How can this vulnerability impact me? :
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.
