Title
jfs: fix array-index-out-of-bounds in dbAdjTree
Summary
In the Linux kernel, the following vulnerability has been resolved:
jfs: fix array-index-out-of-bounds in dbAdjTree
Currently there is a bound check missing in the dbAdjTree while
accessing the dmt_stree. To add the required check added the bool is_ctl
which is required to determine the size as suggest in the following
commit.
