In the Linux kernel, the following vulnerability has been resolved:
net_sched: keep alloc_hash updated after hash allocation
In commit 599be01ee567 ("net_sched: fix an OOB access in cls_tcindex") I moved cp->hash calculation before the first tcindex_alloc_perfect_hash(), but cp->alloc_hash is left untouched. This difference could lead to another out of bound access.
cp->alloc_hash should always be the size allocated, we should update it after this tcindex_alloc_perfect_hash().
