Freeing the IRQ first\nkeeps a trailing handler from re-arming datawork between the cancel and\nthe host free.  Both callbacks are non-self-rearming.\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/23383e0578b58ba2dc0730cf9f7806bd66bf859a","https://git.kernel.org/stable/c/314966b490323bdcfd3162a1398b00e587e0ced4","https://git.kernel.org/stable/c/740f595f8ad678cb4d79f13edd12851df2492bdd","https://git.kernel.org/stable/c/a1ff367e0dc961d73707add508a95df5c3509bd1","https://git.kernel.org/stable/c/ae10838a7cdf0e54caa9d0a4f488704fd04e7f01"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:57:46.668721662+00:00"},"epss":{"cve":"CVE-2026-98210","score":0.00177,"percentile":0.07173,"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).
