Descriptions
In the Linux kernel, the following vulnerability has been resolved: mmc: via-sdmmc: 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 which
will call mmc_free_host().
The SUSE Linux Enterprise 15 SP5 RT kernel was updated to fix various security issues.
