CVE-2023-53192 is a flaw in Linux kernel VXLAN nexthop selection. VXLAN supplied the 32-bit value returned by skb_get_hash() to nexthop code that expects a 31-bit hash. When the high bit is set, the value becomes negative when represented as an int. For resilient nexthop groups, nexthop_select_path_res() can derive an invalid bucket index and access nh_buckets[] out of bounds. Hash-threshold nexthop groups are also affected by skewed path selection toward the first group entry.

A Linux kernel VXLAN out-of-bounds write caused by incorrect nexthop hash sizing that can lead to denial of service.
A Linux kernel VXLAN out-of-bounds write caused by incorrect nexthop hash size that can lead to denial of service.
A Linux kernel VXLAN/nexthop flaw caused by using a 32-bit hash where 31-bit hash values are expected, which can lead to incorrect nexthop selection and out-of-bounds access in nh_buckets[], potentially causing a kernel panic.
