Description
A vulnerability was found in the Linux kernel's ks8851 network driver, that causes a system hang due to a deadlock in the IRQ handling process. The issue occurs when the ks8851_irq() function, which handles network packets, triggers a softirq (net_rx_action) while holding a spinlock (ks8851_lock_par()). This results in a deadlock when the driver tries to acquire the same spinlock again during packet transmission.
