CVE-2023-53192

The CVE-2023-53192 issue affects the Linux kernel vxlan nexthop code where a 32-bit hash returned by skb_get_hash() is used where a 31-bit hash is expected. This can cause int hash to become negative and trigger incorrect nexthop selection or out-of-bounds access in nh_buckets[], risking a kernel...
