CVE-2022-50157
In the Linux kernel, the following vulnerability has been resolved: PCI: microchip: Fix refcount leak in mc_pcie_init_irq_domains() of_get_next_child() returns a node pointer with refcount incremented, so we should use of_node_put() on it when we don't…
Does this matter?
Lower severity and a low EPSS score (0.18%). Track it; it rarely justifies an emergency change on its own.
Description
In the Linux kernel, the following vulnerability has been resolved: PCI: microchip: Fix refcount leak in mc_pcie_init_irq_domains() of_get_next_child() returns a node pointer with refcount incremented, so we should use of_node_put() on it when we don't need it anymore. mc_pcie_init_irq_domains() only calls of_node_put() in the normal path, missing it in some error paths. Add missing of_node_put() to avoid refcount leak.
