Deskripsi CVE

In the Linux kernel, the following vulnerability has been resolved: mmc: mtk-sd: Cancel request timeout work on remove The driver queues req_timeout while a request is active. msdc_request_done() uses cancel_delayed_work(), which does not wait for a timeout callback that has already started. The timeout callback calls mmc_request_done(), which wakes the request waiter, and then continues to use host->dev_comp and check the SDIO IRQ. During unbind, msdc_drv_remove() can return and the managed mmc_host can be freed before the callback finishes. KASAN reported use-after-free accesses in msdc_request_done() and msdc_recheck_sdio_irq() in each of three unbind tests. The same tests completed without a kernel diagnostic after this change. Call cancel_delayed_work_sync() after mmc_remove_host() has stopped new requests and before the driver releases the host resources.
