- Summary
- vdpa/octeon_ep: fix IRQ-to-ring mapping in interrupt handler
- Details
-
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.
