{"schema":"threatline.record/2","record":{"id":"CVE-2026-98210","aliases":[],"summary":"mmc: mxcmmc: cancel data work and watchdog on remove","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nmmc: mxcmmc: cancel data work and watchdog on remove\n\nmxcmci_remove() frees the host through the devm tail, but neither it nor\nmmc_remove_host() drains the driver's own asynchronous state.\nhost->watchdog, a 10 s timer armed on the DMA path in mxcmci_setup_data(),\nis deleted only by the DMA- and IRQ-complete paths, which the remove path\ndoes not explicitly drain; it can therefore fire after the host is freed\nand dereference it in mxcmci_watchdog().  host->datawork, armed from the\nIRQ handler on the PIO path, is not cancelled by the remove path either.\n\nFree the devm-registered IRQ, then cancel datawork and delete the watchdog\nin mxcmci_remove(), before dma_release_channel().  Freeing the IRQ first\nkeeps a trailing handler from re-arming datawork between the cancel and\nthe host free.  Both callbacks are non-self-rearming.\n\nThis issue was found by an in-house static analysis tool.","categories":["Operating
