Descripción
*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
mmc: core: Fix kernel panic when remove non-standard SDIO card<br />
<br />
SDIO tuple is only allocated for standard SDIO card, especially it causes<br />
memory corruption issues when the non-standard SDIO card has removed, which<br />
is because the card device&#39;s reference counter does not increase for it at<br />
sdio_init_func(), but all SDIO card device reference counter gets decreased<br />
at sdio_release_func().
