Deskripsi CVE
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->sdio_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->sdio_irq_work in mmc_free_host(), like the existing
host->detect drain added by commit 1036f69e2513 ("mmc: core: Cancel
delayed work before releasing host").
This issue was found by an in-house static analysis tool.
