Summary
ubi: ubi_create_volume: Fix use-after-free when volume creation failed
Details

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

ubi: ubicreatevolume: Fix use-after-free when volume creation failed

There is an use-after-free problem for 'ebatbl' in ubicreate_volume()'s error handling path:

ubiebareplacetable(vol, ebatbl) vol->ebatbl = tbl outmapping: ubiebadestroytable(ebatbl) // Free 'ebatbl' outunlock: putdevice(&vol->dev) volrelease kfree(tbl->entries) // UAF

Fix it by removing redundant 'eba_tbl' releasing. Fetch a reproducer in [Link].
