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.\n\nRecord 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.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":[],"vendors":[],"products":[],"references":[{"url":"https://git.kernel.org/stable/c/5857035a3b53a4e7b5a0d5a740189901ece0b079","tags":[]},{"url":"https://git.kernel.org/stable/c/7dc6a769153c0457077a0da4888a00f61e66de15","tags":[]},{"url":"https://git.kernel.org/stable/c/814f2da6995772c07a7c9c2cc6028b6e3f3ecc9c","tags":[]},{"url":"https://git.kernel.org/stable/c/d5151496a0a2b19c9c0c7b0ebf86b3de55a8fa3a","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
