The call to\nof_node_put(nchangeset) can decrement the reference count to zero and\nfree the node if there are no other holders. After that, the code still\nuses 'parent' to check for the presence of a property and to read a\nstring property, leading to a use-after-free.\n\nFix this by moving the of_node_put() call after the last access to\n'parent', avoiding the UAF.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"twilight","depthScore":46,"depthScoreParts":{"impact":46.2,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
