  - 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. ``` BUG: spinlock recursion on CPU#0, swapper/0/0
