In the Linux kernel, the following vulnerability has been resolved:
net: ethernet: mtk-star-emac: fix spinlock recursion issues on rx/tx poll
Use spin_lock_irqsave and spin_unlock_irqrestore instead of spin_lock and spin_unlock in mtk_star_emac driver to avoid spinlock recursion occurrence that can happen when enabling the DMA interrupts again in rx/tx poll.
