This leaves the last valid node stored in\nprev without its reference dropped, resulting in a node reference leak.\n\nFix this by changing the final `of_node_put(np)` to `of_node_put(prev)`.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/2560c97f63bb99b26d9f19b23a4f66ea24c9dc14","https://git.kernel.org/stable/c/36e4843fe39ea2f17f4de6d59fba26271916c184","https://git.kernel.org/stable/c/51afb7da697b698996351740b4f39fb05ce2afd4","https://git.kernel.org/stable/c/880ac50b0bfae06d7ab5f1843253adfb86aa173a","https://git.kernel.org/stable/c/bf4a195f063b0a0805c1417f6aad1dd32ea48f0f"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:48:17.459049833+00:00"},"epss":{"cve":"CVE-2026-72179","score":0.00215,"percentile":0.11842,"date":"2026-11-01"},"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).
