CVE-2026-74742

A flaw was found in the Linux kernel's veth component. In a multi-queue setup without an eXpress Data Path XDP program attached, the vethpoll function incorrectly derives the index of the peer transmit TX queue to wake. This can cause a TX queue to stop indefinitely if it becomes full, as the...

CVE-2026-74742

Linux kernel veth has a bug where veth_poll() derives the peer TX queue index from rq->xdp_rxq.queue_index, a field only populated when an XDP program is attached. On the plain GRO/NAPI path the value stays 0 for every queue. In a multi-queue setup with GRO enabled and no XDP, all NAPI pollers...
