CVE-2026-74396

CVE-2026-74396 affects the Linux kernel in the RDMA/mlx5 stack. The issue occurs in the path that allocates and DMA maps an XLT buffer via mlx5r_umr_create_xlt() and releases it through mlx5r_umr_unmap_free_xlt(). If mlx5_odp_populate_xlt() encounters an error, its error path previously returned ...

CVE-2026-74309 vdpa/octeon_ep: fix IRQ-to-ring mapping in interrupt handler

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...
