  "title": "thunderbolt: Don\u0027t access a DP tunnel after its DPRX read was canceled",
  "description": "In the Linux kernel, the following vulnerability has been resolved:  thunderbolt: Don\u0027t access a DP tunnel after its DPRX read was canceled  tb_dp_dprx_work() checks -\u003Edprx_canceled before it takes tb-\u003Elock so it misses a tb_dp_dprx_stop() that could not cancel the already running work. It then polls the DPRX capabilities and runs the callback for a tunnel that has already been torn down while the domain is suspending or going away.  This can be hit by cancelling the DPRX read from outside the ordered tb-\u003Ewq: During suspend tb_disconnect_and_release_dp() does just this and with a later patch tb_stop() will do it as well. The latter in combination with the Apple NHI where the DPRX read never completed is how I hit this.  Check the flag with tb-\u003Elock held instead and check it again in tb_dp_tunnel_active() because the callback runs after the lock has been dropped again.  Also clear the flag in tb_dp_dprx_start() so that it only ever describes the work that is currently in flight.",
