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

jfs: upper bound check of tree index in dbAllocAG

When computing the tree index in dbAllocAG, we never check if we are out of bounds realative to the size of the stree. This could happen in a scenario where the filesystem metadata are corrupted.
