  "title": "of/overlay: put property on deadprops only after changeset add succeeds",
  "description": "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\u0027s 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\u0027s 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\u0027s property lists, so the order of the two steps is otherwise immaterial, and the error path frees a property that nothing references.",
