CVE-2026-74309

In the Linux kernel, the following vulnerability has been resolved: vdpa/octeonep: fix IRQ-to-ring mapping in interrupt handler Look up the IRQ index in octhw-irqs instead of assuming irq - irqs0. This supports non-contiguous IRQ numbers and avoids incorrect ring indexing when irqs0 is not the ba...

CVE-2026-74309

The CVE-2026-74309 entry documents a Linux kernel issue in the vdpa/octeon_ep component where interrupt handling incorrectly mapped IRQs to rings. The root cause is assuming irq - irqs[0] to locate the IRQ index; the fix updates the code to look up the IRQ index within oct_hw->irqs, allowing n...
