In the Linux kernel, the following vulnerability has been resolved:
virtio-pci: Check if is_avq is NULL
[bug] In the virtio_pci_common.c function vp_del_vqs, vp_dev->is_avq is involved to determine whether it is admin virtqueue, but this function vp_dev->is_avq may be empty. For installations, virtio_pci_legacy does not assign a value to vp_dev->is_avq.
[fix] Check whether it is vp_dev->is_avq before use.
