In the Linux kernel, the following vulnerability has been resolved:
drm/mediatek: fix potential OF node use-after-free
The for_each_child_of_node() helper drops the reference it takes to each
node as it iterates over children and an explicit of_node_put() is only
needed when exiting the loop early.
Drop the recently introduced bogus additional reference count decrement
at each iteration that could potentially lead to a use-after-free.
