Summary
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: ================================================================== BUG: kernel NULL pointer dereference, address:0000000000000000 ...
