Descriptions

In the Linux kernel, the following vulnerability has been resolved: mmc: mmc_spi: fix error handling in mmc_spi_probe() If mmc_add_host() fails, it doesn't need to call mmc_remove_host(),
or it will cause null-ptr-deref, because of deleting a not added
device in mmc_remove_host(). To fix this, goto label 'fail_glue_init', if mmc_add_host() fails,
and change the label 'fail_add_host' to 'fail_gpiod_request'.

En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: mmc: mmc_spi: corrige el manejo de errores en mmc_spi_probe(). Si mmc_add_host() falla, no es necesario llamar a mmc_remove_host(), o causará null-ptr-deref, debido a la eliminación de un dispositivo no agregado en mmc_remove_host(). Para solucionar este problema, vaya a la etiqueta 'fail_glue_init', si mmc_add_host() falla, y cambie la etiqueta 'fail_add_host' a 'fail_gpiod_request'.
