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...

In the Linux kernel, the following vulnerability has been resolved: ixgbe: Fix panic during XDPTX with 64 CPUs Commit 4fe815850bdc "ixgbe: let the xdpdrv work with more than 64 cpus" adds support to allow XDP programs to run on systems with more than 64 CPUs by locking the XDP TX rings and indexi...

CVE-2023-54090

CVE-2023-54090 affects the Linux kernel ixgbe XDP path on systems with more than 64 CPUs. Root cause: ixgbe_determine_xdp_q_idx could return cpu instead of cpu % IXGBE_MAX_XDP_QS, leading to an array-index-out-of-bounds in ixgbe.h and a kernel panic (and potential NULL dereference) when XDP_TX ru...

CVE-2023-54090 ixgbe: Fix panic during XDP_TX with > 64 CPUs

kernel: ixgbe: Fix panic during XDP_TX with > 64 CPUs

A flaw was found in the Linux kernel's ixgbe network driver. On systems with more than 64 CPUs, XDPTX operations can cause a kernel panic due to an array-index-out-of-bounds access. The ixgbexdplockingkey variable can be incorrectly decremented to zero during ring reconfiguration, causing the...
