Otherwise the handler could\nre-arm the work and run it after the xadc structure has been freed.\n\nThis issue was found by an in-house static analysis tool.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/012451d72c12293918617ff98cc737bedad21910","https://git.kernel.org/stable/c/0f3f427076240e75ff265e61645627a71ca4918c","https://git.kernel.org/stable/c/49ea8a359e362bfbb32a647c8eb7962fbb37234e","https://git.kernel.org/stable/c/a29d385ad7b340c952a3935af2b33488db1eb3a6","https://git.kernel.org/stable/c/a5fe2d1b55faba6d00fd87ad491b6cb603046304"],"products":[],"source":"nvd","synced_at":"2026-10-22T16:41:11.231219466+00:00"},"epss":{"cve":"CVE-2026-98670","score":0.00168,"percentile":0.05973,"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).
