      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nmmc: mtk-sd: Cancel request timeout work on remove\n\nThe driver queues req_timeout while a request is active.\nmsdc_request_done() uses cancel_delayed_work(), which does not wait for\na timeout callback that has already started.\n\nThe timeout callback calls mmc_request_done(), which wakes the request\nwaiter, and then continues to use host->dev_comp and check the SDIO IRQ.\nDuring unbind, msdc_drv_remove() can return and the managed mmc_host can\nbe freed before the callback finishes.\n\nKASAN reported use-after-free accesses in msdc_request_done() and\nmsdc_recheck_sdio_irq() in each of three unbind tests.  The same tests\ncompleted without a kernel diagnostic after this change.\n\nCall cancel_delayed_work_sync() after mmc_remove_host() has stopped new\nrequests and before the driver releases the host resources.",
