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

device property: initialize the remaining fields of fwnode_handle in fwnode_init()

If a firmware node is allocated on the stack (for instance: temporary

software node whose life-time we control) or on the heap - but using a

non-zeroing allocation function - and initialized using fwnode_init(),

its secondary pointer will contain uninitialized memory which likely

will be neither NULL nor IS_ERR() and so may end up being dereferenced

(for example: in dev_to_swnode()). Set fwnode->secondary to NULL on

initialization. While at it: initialize the remaining fields of struct

fwnode_handle too just to be sure.
