CVE-2026-74614

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.
