CVE-2026-80694

In the Linux kernel, the following vulnerability has been resolved: net: ethernet: mtk_eth_soc: pass eth to mtk_handle_irq_rx in poll_controller mtk_handle_irq_rx expects a struct mtk_eth * (matching the request_irq cookie), but mtk_poll_controller incorrectly passed the net_device *. Calling ndo_poll_controller with CONFIG_NET_POLL_CONTROLLER enabled would then crash.
