The work can subsequently\ndereference the devm-allocated mmci_host after it has been released.\n\nMask the controller interrupts and disable the delayed work during\nremoval. This drains any queued instance and stops an IRQ handler that\nis still in progress from queueing the work again once it has been\ndisabled.\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/2b19cf3e50cddaff07b657dae1a8f30f06032852","https://git.kernel.org/stable/c/432b98c1f5daecf04a33c8e1688d26e7ac221e23","https://git.kernel.org/stable/c/7fecf79f31568de161be14911db10d1251617b01","https://git.kernel.org/stable/c/af6fbf72e899932f330c4e5d0b84d985c922c633"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:57:46.668721662+00:00"},"epss":{"cve":"CVE-2026-98211","score":0.00206,"percentile":0.10459,"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).
