What to Know

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. (NVD)

What to Do

Monitor Linux's web page for any future patch releases.
