  "description": "In the Linux kernel, the following vulnerability has been resolved:  x86/amd_node: Fix PCI device reference counting in amd_smn_init()  The local \u0022root\u0022 pointer is a temporary variable used during the device search. Therefore, refcount related to the search iterators should be cleaned up after the search is complete.  Use the __free() cleanup macro to ensure the refcount is decremented when the temporary pointer goes out of scope.  Additionally, increment the refcount when caching a root pointer. This ensures the in-use refcount is separate from the temporary search refcounting.  Finally, drop the redundant \u0022root = NULL\u0022 before the second search loop. The pci_get_class() iterator always decrements the refcount of its \u0022from\u0022 argument, so the first loop can only fall through with \u0022root\u0022 already NULL.",
