In the Linux kernel, the following vulnerability has been resolved:<\/p>\n
of\/overlay: put property on deadprops only after changeset add succeeds<\/p>\n
add_changeset_property() links a new property of a not-yet-live
\ntarget node into the node’s deadprops list before handing it to
\nof_changeset_add_property(). If that fails, the error path frees the
\nproperty but leaves the freed pointer linked in deadprops, and
\nof_node_release() frees it a second time when the aborted overlay’s
\nnode is released.<\/p>\n
Record the changeset entry first and link the property into deadprops
\nonly on success. of_changeset_add_property() never looks at the
\nnode’s property lists, so the order of the two steps is otherwise
\nimmaterial, and the error path frees a property that nothing
\nreferences.<\/p>\n","protected":false},"excerpt":{"rendered":"
