In the Linux kernel, the following vulnerability has been resolved:<\/p>\n
mmc: core: Cancel SDIO IRQ work before freeing host<\/p>\n
A host controller that uses sdio_signal_irq() schedules host->sdio_irq_work
\nfrom its interrupt handler. That work is only cancelled on the suspend
\npath (mmc_sdio_suspend()), not on the remove\/free path, so a worker armed
\njust before the controller freed its IRQ can run after
\nmmc_host_classdev_release() has freed the host and dereference it through
\ncontainer_of().<\/p>\n
Cancel host->sdio_irq_work in mmc_free_host(), like the existing
\nhost->detect drain added by commit 1036f69e2513 (“mmc: core: Cancel
\ndelayed work before releasing host”).<\/p>\n
