{"id":"CVE-2026-98212","published":"2026-10-06T09:18:07.627","lastModified":"2026-10-06T09:18:07.627","description":"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.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":[],"vendors":[],"products":[],"references":[{"url":"https://git.kernel.org/stable/c/45341b341642c377192c95e4d48e0a859cf85f42","tags":[]},{"url":"https://git.kernel.org/stable/c/5d132990475f02cfa1debe03d50b479432864ebd","tags":[]},{"url":"https://git.kernel.org/stable/c/8439bf262ce3267bcfee29d3c61605f1731a2271","tags":[]},{"url":"https://git.kernel.org/stable/c/c50d6515bffb148c2c12be6d587ec201dfab4c34","tags":[]},{"url":"https://git.kernel.org/stable/c/df2eb59fd9eb33663dc1053f5a4ed851e0aa1f67","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
