  "details": "In the Linux kernel, the following vulnerability has been resolved:  mmc: core: Cancel SDIO IRQ work before freeing host  A host controller that uses sdio_signal_irq() schedules host-\u003esdio_irq_work from its interrupt handler.  That work is only cancelled on the suspend path (mmc_sdio_suspend()), not on the remove/free path, so a worker armed just before the controller freed its IRQ can run after mmc_host_classdev_release() has freed the host and dereference it through container_of().  Cancel host-\u003esdio_irq_work in mmc_free_host(), like the existing host-\u003edetect drain added by commit 1036f69e2513 (\"mmc: core: Cancel delayed work before releasing host\").  This issue was found by an in-house static analysis tool.",
