In the Linux kernel, the following vulnerability has been resolved: ata: libata-transport: fix error handling in ata_tlink_add() In ata_tlink_add(), the return value of transport_add_device() is not checked. As a result, it causes null-ptr-deref while removing the module, because transport_remove_device() is called to remove the device that was not added.
