CVE-2023-53192

The CVE-2023-53192 issue is a Linux kernel bug in vxlan nexthop hashing. The nexthop code expected a 31-bit hash, but skb_get_hash() can return a 32-bit value which becomes negative in a signed int. This can trigger incorrect nexthop selection (nexthop_select_path_hthr) or out-of-bounds access in...
