Technical Description

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.
