CVE-2023-54205

Estado: AplazadaSin puntuar—

In the Linux kernel, the following vulnerability has been resolved:

pinctrl: stm32: Fix refcount leak in stm32_pctrl_get_irq_domain

of_irq_find_parent() returns a node pointer with refcount incremented, We should use of_node_put() on it when not needed anymore. Add missing of_node_put() to avoid refcount leak.
