CVE-2022-50670

Description

In the Linux kernel, the following vulnerability has been resolved:

mmc: omap_hsmmc: fix return value check of mmc_add_host()

mmc_add_host() may return error, if we ignore its return value, it will lead two issues: 1. The memory that allocated in mmc_alloc_host() is leaked. 2. In the remove() path, mmc_remove_host() will be called to delete device, but it's not added yet, it will lead a kernel crash because of null-ptr-deref in device_del().

Fix this by checking the return value and goto error path wihch will call mmc_free_host().
