CVE-2022-50640

Estado: AplazadaSin puntuar—

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().
