CVE-2026-90083

CVE-2026-90083 affects the Linux kernel's net/sched act_ife (IFE) traffic control action. The IFE action uses skb->dev->hard_header_len as the Ethernet header length, which is incorrect on non-Ethernet devices (e.g., PPP reports PPP_HDRLEN while nothing is stripped on ingress). When a packe...
