Lower severity and a low EPSS score (0.26%). Track it; it rarely justifies an emergency change on its own.
Description
In the Linux kernel, the following vulnerability has been resolved: dmaengine: ti: k3-udma-private: Fix refcount leak bug in of_xudma_dev_get() We should call of_node_put() for the reference returned by of_parse_phandle() in fail path or when it is not used anymore. Here we only need to move the of_node_put() before the check.
