{"schema":"threatline.record/2","record":{"id":"CVE-2026-98213","aliases":[],"summary":"mmc: core: Cancel SDIO IRQ work before freeing host","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nmmc: core: Cancel SDIO IRQ work before freeing host\n\nA 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().\n\nCancel 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\").\n\nThis issue was found by an in-house static analysis tool.","categories":["Operating
