In the Linux kernel, the following vulnerability has been resolved:
vdpa/octeon_ep: fix IRQ-to-ring mapping in interrupt handler
Look up the IRQ index in oct_hw->irqs instead of assuming
irq - irqs[0]. This supports non-contiguous IRQ numbers and
avoids incorrect ring indexing when irqs[0] is not the base.
