Description
In the Linux kernel, the following vulnerability has been resolved: jfs: check if leafidx greater than num leaves per dmap tree syzbot report a out of bounds in dbSplit, it because dmt_leafidx greater than num leaves per dmap tree, add a checking for dmt_leafidx in dbFindLeaf. Shaggy: Modified sanity check to apply to control pages as well as leaf pages.
