CVE-2022-50640 is a vulnerability of currently unknown severity. In the Linux kernel, the following vulnerability has been resolved: mmc: core: Fix kernel panic when remove non-standard SDIO card SDIO tuple is only allocated for standard SDIO card, especially it causes memory corruption issues when the non-standard SDIO card has removed, which is because the card device's reference counter does not increase for it at sdio_init_func(), but all SDIO card device reference counter gets decreased at sdio_release_func().. EPSS estimates a 0.18% chance of exploitation in the next 30 days.
