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.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/5857035a3b53a4e7b5a0d5a740189901ece0b079","https://git.kernel.org/stable/c/7dc6a769153c0457077a0da4888a00f61e66de15","https://git.kernel.org/stable/c/814f2da6995772c07a7c9c2cc6028b6e3f3ecc9c","https://git.kernel.org/stable/c/936f1ffcb87a1c50938a21176a6463af162cf4b5","https://git.kernel.org/stable/c/d5151496a0a2b19c9c0c7b0ebf86b3de55a8fa3a"],"products":[],"source":"nvd","synced_at":"2026-10-22T16:41:11.231219466+00:00"},"epss":{"cve":"CVE-2026-98855","score":0.00157,"percentile":0.04769,"date":"2026-10-25"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
