Description

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