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...

CVE-2026-80661

CVE-2026-80661 affects the Linux kernel UFS tracing subsystem (drivers/ufs/core/ufs_trace.h). The root cause is an illegal pointer dereference in TP_printk(): the function reads the dev_name by dereferencing a saved hba pointer from the ring buffer, but TP_printk() executes when /sys/kernel/traci...
