CVE-2025-38192

CVE-2025-38192 is a Linux kernel vulnerability where an ingress NAT46 BPF program that flips IPv4/IPv6 can mutate skb->protocol to v6 while the dst remains IPv4, leading to a NULL pointer dereference in ip6_rcv_core. The fix is to clear the destination (dst) in all BPF helpers that change skb-...
