Description

virtio_pci: Fix admin vq cleanup by using correct info pointer

In the Linux kernel, the following vulnerability has been resolved:

virtio_pci: Fix admin vq cleanup by using correct info pointer

vp_modern_avq_cleanup() and vp_del_vqs() clean up admin vq

resources by virtio_pci_vq_info pointer. The info pointer of admin

vq is stored in vp_dev->admin_vq.info instead of vp_dev->vqs[].

Using the info pointer from vp_dev->vqs[] for admin vq causes a

kernel NULL pointer dereference bug.

In vp_modern_avq_cleanup() and vp_del_vqs(), get the info pointer

from vp_dev->admin_vq.info for admin vq to clean up the resources.

Also make info ptr as argument of vp_del_vq() to be symmetric with

vp_setup_vq().

vp_reset calls vp_modern_avq_cleanup, and causes the Call Trace:
