In the Linux kernel, the following vulnerability has been resolved:
pinctrl: intel: platform: fix error path in deviceforeachchildnode()
The deviceforeachchildnode() loop requires calls to fwnodehandleput() upon early returns to decrement the refcount of the child node and avoid leaking memory if that error path is triggered.
There is one early returns within that loop in intelplatformpinctrlpreparecommunity(), but fwnodehandleput() is missing.
Instead of adding the missing call, the scoped version of the loop can be used to simplify the code and avoid mistakes in the future if new early returns are added, as the child node is only used for parsing, and it is never assigned.
