{"schema":"threatline.record/2","record":{"id":"CVE-2026-98212","aliases":[],"summary":"mmc: hsq: Fix use-after-free in retry work","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nmmc: hsq: Fix use-after-free in retry work\n\nmmc_hsq_pump_requests() queues retry_work when request_atomic() returns\n-EBUSY; today sdhci-sprd is the only consumer that implements\nrequest_atomic(). 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.","categories":["Operating systems"],"product":"Linux","vendor":"Linux","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98212","source_modified_at":"2026-10-19T09:15:43.105Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"Linux","vendor":"Linux","versions":[{"version":"6db96e5810e0a6a345b7d78549de7676ae5b2662","lessThan":"c50d6515bffb148c2c12be6d587ec201dfab4c34","status":"affected","versionType":"git"},{"version":"6db96e5810e0a6a345b7d78549de7676ae5b2662","lessThan":"df2eb59fd9eb33663dc1053f5a4ed851e0aa1f67","status":"affected","versionType":"git"},{"version":"6db96e5810e0a6a345b7d78549de7676ae5b2662","lessThan":"8439bf262ce3267bcfee29d3c61605f1731a2271","status":"affected","versionType":"git"},{"version":"6db96e5810e0a6a345b7d78549de7676ae5b2662","lessThan":"45341b341642c377192c95e4d48e0a859cf85f42","status":"affected","versionType":"git"},{"version":"6db96e5810e0a6a345b7d78549de7676ae5b2662","lessThan":"5d132990475f02cfa1debe03d50b479432864ebd","status":"affected","versionType":"git"}],"defaultStatus":"unaffected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98212","source_modified_at":"2026-10-19T09:15:43.105Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"Linux","vendor":"Linux","versions":[{"version":"5.8","status":"affected"},{"version":"0","lessThan":"5.8","status":"unaffected","versionType":"semver"},{"version":"6.6.158","lessThanOrEqual":"6.6.*","status":"unaffected","versionType":"semver"},{"version":"6.12.112","lessThanOrEqual":"6.12.*","status":"unaffected","versionType":"semver"},{"version":"6.18.54","lessThanOrEqual":"6.18.*","status":"unaffected","versionType":"semver"},{"version":"7.2.8","lessThanOrEqual":"7.2.*","status":"unaffected","versionType":"semver"},{"version":"7.3","lessThanOrEqual":"*","status":"unaffected","versionType":"original_commit_for_fix"}],"defaultStatus":"affected"}],"fixed_versions":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98212","source_modified_at":"2026-10-19T09:15:43.105Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"8439bf262ce3267bcfee29d3c61605f1731a2271","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98212","source_modified_at":"2026-10-19T09:15:43.105Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"45341b341642c377192c95e4d48e0a859cf85f42","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98212","source_modified_at":"2026-10-19T09:15:43.105Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"5d132990475f02cfa1debe03d50b479432864ebd","basis":"first unaffected version stated in the CVE record"}],"cvss":null,"severity":null,"kev":{"listed":false},"epss":{"probability":0.00209,"percentile":0.10465,"score_date":"2026-10-23"},"published_at":"2026-10-06T08:44:48.498Z","modified_at":"2026-10-19T09:15:43.105Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-98212","fetched_at":"2026-10-23T18:45:31.882637Z","source_modified_at":"2026-10-19T09:15:43.105Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-98212","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://git.kernel.org/stable/c/c50d6515bffb148c2c12be6d587ec201dfab4c34"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/df2eb59fd9eb33663dc1053f5a4ed851e0aa1f67"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/8439bf262ce3267bcfee29d3c61605f1731a2271"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/45341b341642c377192c95e4d48e0a859cf85f42"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/5d132990475f02cfa1debe03d50b479432864ebd"}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":"product","confidence":"heuristic","reviewed":false},"change_timestamp":"2026-10-19T09:15:43.105Z","content_hash":"802a8c74a06977ee4d1ebdef776c716d603a7dc1be388f2fb1ff6ebddd81a064"}}
