  3. CVE-2022-50154
In the Linux kernel, the following vulnerability has been resolved: PCI: mediatek-gen3: Fix refcount leak in mtk_pcie_init_irq_domains() of_get_child_by_name() returns a node pointer with refcount incremented, so we should use of_node_put() on it when we don't need it anymore. Add missing of_node_put() to avoid refcount leak.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: PCI: mediatek-gen3: Se corrige la fuga de recuento de referencias en mtk_pcie_init_irq_domains(). of_get_child_by_name() devuelve un puntero de nodo con el recuento de referencias incrementado, por lo que debemos usar of_node_put() cuando ya no lo necesitemos. Se ha añadido la función of_node_put() que falta para evitar la fuga de recuento de referencias.
