CVE-2022-50858 is a vulnerability of currently unknown severity. In the Linux kernel, the following vulnerability has been resolved: mmc: alcor: fix return value check of mmc_add_host() mmc_add_host() may return error, if we ignore its return value, the memory that allocated in mmc_alloc_host() will be leaked and it will lead a kernel crash because of deleting not added device in the remove path. So fix this by checking the return value and calling mmc_free_host() in the error path.. EPSS estimates a 0.21% chance of exploitation in the next 30 days.
