Summary
of/overlay: put property on deadprops only after changeset add succeeds
Details

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

of/overlay: put property on deadprops only after changeset add succeeds

add_changeset_property() links a new property of a not-yet-live target node into the node's deadprops list before handing it to of_changeset_add_property(). If that fails, the error path frees the property but leaves the freed pointer linked in deadprops, and of_node_release() frees it a second time when the aborted overlay's node is released.

Record the changeset entry first and link the property into deadprops only on success. of_changeset_add_property() never looks at the node's property lists, so the order of the two steps is otherwise immaterial, and the error path frees a property that nothing references.
