CVE-2025-40173

CVE-2025-40173 affects the Linux kernel’s net/ip6_tunnel code. The issue is described as an IPv6 tunnel headroom growth similar to the IPv4 case, where headroom was previously unbounded and now the IPv6 version is updated to reflect the IPv4 headroom ceiling. The consequence is described as a vul...
