  "description": "In the Linux kernel, the following vulnerability has been resolved:  net_sched: keep alloc_hash updated after hash allocation  In commit 599be01ee567 (\u0022net_sched: fix an OOB access in cls_tcindex\u0022) I moved cp-\u003Ehash calculation before the first tcindex_alloc_perfect_hash(), but cp-\u003Ealloc_hash is left untouched. This difference could lead to another out of bound access.  cp-\u003Ealloc_hash should always be the size allocated, we should update it after this tcindex_alloc_perfect_hash().",
