Description OSIDB Bzimport 2025-12-24 12:02:59 UTC 
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.
