The work is embedded in a devm-allocated mmc_hsq, but\nis never cancelled during driver removal. Work still pending at unbind\ncan therefore run after the devm allocation has been released and\ndereference hsq->mmc and hsq->mrq.\n\nUse devm_work_autocancel() to cancel and drain retry_work before the devm\nallocation is released. By the time devres cleanup begins,\nmmc_remove_host() has already stopped the host, so no new requests can\narm the work.\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/45341b341642c377192c95e4d48e0a859cf85f42","https://git.kernel.org/stable/c/5d132990475f02cfa1debe03d50b479432864ebd","https://git.kernel.org/stable/c/8439bf262ce3267bcfee29d3c61605f1731a2271","https://git.kernel.org/stable/c/c50d6515bffb148c2c12be6d587ec201dfab4c34","https://git.kernel.org/stable/c/df2eb59fd9eb33663dc1053f5a4ed851e0aa1f67"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:57:46.668721662+00:00"},"epss":{"cve":"CVE-2026-98212","score":0.00206,"percentile":0.1046,"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).
