CVE-2026-80613

CVE-2026-80613 affects the Linux kernel veth (virtual ethernet) driver in its XDP enablement error/rollback path . During XDP enablement, if xdp_rxq_info_reg() or xdp_rxq_info_reg_mem_model() fails, the rollback loop for (i--; i >= start; i--) decrements the index before the first iteration. W...

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...

CVE-2026-74612

A flaw was found in the Linux kernel's veth component. A remote attacker could exploit incorrect packet buffer skb length accounting after an eXpress Data Path XDP fragment adjustment. This could lead to the disclosure of sensitive kernel memory information to userspace and corruption or truncati...

Astra Linux – Vulnerability found in Linux 5.15, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: net: veth: The GRO flag is cleared when XDP is disabled, even when the device is disabled. The NETIFFGRO flag is set automatically when XDP is enabled, because both features use the same NAPI mechanism. The logic for clearing the...

CVE-2026-74612

CVE-2026-74612 is a CRITICAL (CVSS 10.0) flaw in the Linux kernel's veth component. When an XDP program shrinks the fragment area, veth_xdp_rcv_skb() fails to update skb->len, causing skb_headlen() to exceed the actual linear area. In the UDP receive path, __skb_datagram_iter() then copies 102...
