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.

The advisory is shared for download at git.kernel.org. This vulnerability was named CVE-2022-50703 since 12/24/2025. The exploitation appears to be easy. There are known technical details, but no exploit is available.
