CVE-2026-31684

The CVE-2026-31684 issue is in the Linux kernel’s net/sched pathology (act_csum) where tcf_csum_act() reads nested VLAN headers directly from skb->data if the payload contains VLAN tags, and may read VLAN_HLEN bytes before guaranteeing the full header is present. The root cause is that the cod...
