If of_node_put() drops the last reference, the later %pOF\nformatting can dereference a freed device node.\n\nKeep the node reference until after the error message has been emitted in\nthe infracfg and SMI lookup paths. Also drop the SMI node before\nreturning when the SMI phandle is missing.","published":"2026-09-03T08:26:30.751Z","modified":"2026-09-05T03:48:19.453824137Z","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":"6.18.46"}],"fix":null,"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/10bf2d7261d7f724ed43a09eea4c90c19c0230a0"},{"type":"WEB","url":"https://git.kernel.org/stable/c/3e013bc8b941bd52c8e3a99798d0ae8792cb71ca"},{"type":"WEB","url":"https://git.kernel.org/stable/c/970b9c83a07c405fdd32bcce7cc4c9e670e58875"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/80xxx/CVE-2026-80750.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-80750"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-09-05T03:48:19.453824137Z"}}
