CVE-2026-64457

The CVE-2026-64457 issue affects the Linux kernel’s virtio_pci subsystem. When unbinding a virtio balloon device (e.g., echo virtio0 > /sys/bus/virtio/drivers/virtio_balloon/unbind), a NULL pointer dereference can occur due to a mismatch between sparse queue indices and dense queue indices (ho...
