During unbind,\nthis causes improper SGI cleanup leading to kernel crash.\n\nAdd explicit irq_type field to pdata for reliable identification of SGI\ninterrupts (type-2) and only clean up SGI resources when appropriate.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/1ee147efee68be00203b1fee6479911debb1edb2","https://git.kernel.org/stable/c/32bf7c6e01f5ba17a53ba236a770bd0274cefdf4","https://git.kernel.org/stable/c/bb160e791ab15b89188a7a19589b8e11f681bef3"],"products":[],"source":"nvd","synced_at":"2026-10-21T03:43:09.190223697+00:00"},"epss":{"cve":"CVE-2025-40161","score":0.00197,"percentile":0.09315,"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).
