      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nmmc: via-sdmmc: stop card-detect handling on probe failure\n\nrequest_irq() registers the SD card-detect interrupt and the probe enables\nit before mmc_add_host() runs. If mmc_add_host() fails, the error path only\nunmaps the registers and returns: the interrupt stays registered, so the\nhandler keeps running against the host once it is freed. via_sdc_isr()\ndereferences sdhost and its MMIO base and schedules carddet_work, which\nvia_sdc_card_detect() also runs against freed memory through its\ncontainer_of() dereference.\n\nAdd a probe-error path that disables and frees the interrupt and cancels\ncarddet_work before unmapping. carddet_work can re-enable the device\ninterrupt via via_reset_pcictrl(), which restores PCIINTCTRL, so mask it\nagain after cancelling the work.\n\nThis issue was found by an in-house static analysis tool and confirmed by\nmanual code review.",
