Yes, it may, as long as the flash is supported by the MTD layer. UBI does not use OOB and it requires data to be written sequentially (see -here). UBI guarantees that the difference +here). UBI guarantees that the difference between maximum and minimum erase-counters is withing certain threshold, which is 4096 by default. Since MLC flashes have quite low eraseblock life-cycle (about 1000-10000, unlike 100000-1000000 for SLC NAND and NOR
