Summary
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)
hex dump (first 32 bytes):
ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ................
ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ................
backtrace:
[<ffffffff8176cecd>] __kmalloc+0x4d/0x150
[<ffffffffa02a9a36>] ubi_eba_create_table+0x76/0x170 [ubi]
[<ffffffffa029764e>] ubi_resize_volume+0x1be/0xbc0 [ubi]
[<ffffffffa02a3321>] ubi_cdev_ioctl+0x701/0x1850 [ubi]
[<ffffffff81975d2d>] __x64_sys_ioctl+0x11d/0x170
[<ffffffff83c142a5>] do_syscall_64+0x35/0x80
[<ffffffff83e0006a>] entry_SYSCALL_64_after_hwframe+0x46/0xb0
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)
