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