  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nthunderbolt: Make the DP tunnel activation callback mandatory\n\ntb_tunnel_alloc_dp() takes an optional callback which is run from\ndprx_work once the DPRX capabilities read has completed. Without that\ncallback tb_dp_dprx_start() reads the capabilities synchronously and\nnever queues the work. It however always takes a tunnel reference which\nis only dropped by dprx_work itself or by tb_dp_dprx_stop() when\ncancel_delayed_work() actually canceled that work. That reference is\nthus leaked for every tunnel without a callback.\n\nThe only tunnels without one are those from tb_tunnel_discover_dp(),\nwhich are activated again when restoring from hibernation.\nPass the callback to tb_tunnel_discover_dp() as well and drop the\nsynchronous path such that the DPRX capabilities are always read from\ndprx_work. Hibernation restore then also no longer blocks for up to 12\nseconds while waiting for that read to complete.\n\nAlso fix up the KUnit tests.",
