  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nvsock/virtio: read virtqueues under worker locks\n\nCommit bd50c5dc182b (\"vsock/virtio: add support for device\nsuspend/resume\") made the *_run flags transition from false to true when\nrestore installs replacement virtqueues.  The RX, TX and event workers\nread their virtqueue before locking and checking the corresponding flag,\nso a worker delayed across freeze and restore can observe the replacement\nqueue's running state while retaining a pointer to the deleted queue.\n\nRead each virtqueue under its mutex after checking the run flag, keeping\nthe pointer and state in the same queue generation.",
