CVE-2026-80612
This Linux kernel vulnerability affects the net lwtunnel (lightweight tunnel) subsystem. When LWT encapsulation prepends outer headers, it moves skb->data over the headroom where XDP/TC skb metadata resides. Non-BPF encaps types (MPLS, Seg6, IOAM6) silently overwrite this metadata via skb_push...
