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

ubi: Fix unreferenced object reported by kmemleak in ubi_resize_volume()

There is a memory leaks problem reported by kmemleak:

unreferenced object 0xffff888102007a00 (size 128):

comm "ubirsvol", pid 32090, jiffies 4298464136 (age 2361.231s)

This is due to a mismatch between create and destroy interfaces, and

in detail that "new_eba_tbl" created by ubi_eba_create_table() but

destroyed by kfree(), while will causing "new_eba_tbl->entries" not

freed.

Fix it by replacing kfree(new_eba_tbl) with

ubi_eba_destroy_table(new_eba_tbl)
