CVE-2025-40183

CVE-2025-40183 is a Linux kernel in-kernel bug in the eBPF networking path. The issue stems from the metadata_dst object allocated for vxlan-decapped traffic when using bpf_redirect_neigh(), which could leak because an existing dst entry was not dropped before attaching a new one, leading to pote...
