  "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-\u003emmc and hsq-\u003emrq.\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.",
