The\nfunction immediately calls of_node_put(np), releasing the reference and\nleaving pdev->dev.of_node as a dangling pointer.\n\nRemove the of_node_put(np) call to let the device hold the reference.","published":"2026-09-11T19:43:52.024Z","modified":"2026-09-14T03:46:05.418622608Z","cvss":{"score":8.4,"severity":"HIGH","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[{"ecosystem":"Linux","name":"Kernel","fixedVersion":"6.12.109"}],"fix":null,"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/8648e29e5c01b6b677c704049189287e27255ccb"},{"type":"WEB","url":"https://git.kernel.org/stable/c/95342d26f9c6b68a46ab57fa48428a3c4a423dd7"},{"type":"WEB","url":"https://git.kernel.org/stable/c/d3c1316d84e0a036890b00ae6e4c0b0b80f70c25"},{"type":"WEB","url":"https://git.kernel.org/stable/c/f9324d670ae0b88cbfb0aa48fcaefa5baeb8da4c"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/89xxx/CVE-2026-89504.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-89504"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-09-14T03:46:05.418622608Z"}}
