  "details": "In the Linux kernel, the following vulnerability has been resolved:  vsock/virtio: avoid refilling the RX queue after teardown  Commit b917507e5ad9 (\"vsock/virtio: stop workers during the .remove()\") made the RX worker jump to its common exit when rx_run is clear.  That exit still refills the RX queue when the buffer count is low, so work queued across virtio_vsock_vqs_del() can add buffers after the virtqueues have been deleted.
