CVE-2026-80694

CVE-2026-80694 is a type-mismatch bug in the Linux kernel's MediaTek mtk_eth_soc Ethernet driver. The function mtk_poll_controller incorrectly passed a net_device * to mtk_handle_irq_rx, which expects a struct mtk_eth * (the request_irq cookie). Calling ndo_poll_controller with CONFIG_NET_POLL_CO...
