In the Linux kernel, the following vulnerability has been resolved:
thunderbolt: Tear down inactive DP tunnels when the domain is stopped
tb stop() only tears down DMA tunnels so a DP tunnel that is still waiting for dprx work to complete keeps that work queued while the routers are removed and the control channel is stopped. The work only stops once the DPRX timeout has passed and because it requeues itself until then the flush workqueue() in tb domain remove() won't wait for its final run. The callback then runs against a domain that is already torn down. A reference to that domain is kept so the completion waiting for that domain to disappear in unbind will block until the timeout is eventually reached.
Tear down DP tunnels that are not active yet as well which also cancels that work. Tunnels for displays that are already alive are untouched and keep working.
