Summary
vsock/virtio: read virtqueues under worker locks
Details

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

vsock/virtio: read virtqueues under worker locks

Commit bd50c5dc182b ("vsock/virtio: add support for device suspend/resume") made the *_run flags transition from false to true when restore installs replacement virtqueues. The RX, TX and event workers read their virtqueue before locking and checking the corresponding flag, so a worker delayed across freeze and restore can observe the replacement queue's running state while retaining a pointer to the deleted queue.

Read each virtqueue under its mutex after checking the run flag, keeping the pointer and state in the same queue generation.
