AI-suggested
A fix is available and has been applied in the Linux kernel. Users should update to the fixed kernel versions or apply the relevant patches to ensure the DP tunnel activation callback is mandatory and the synchronous path is removed. No additional mitigation actions are indicated.
Description
A vulnerability in the Linux kernel's Thunderbolt driver was fixed by making the DisplayPort (DP) tunnel activation callback mandatory. Previously, tunnels created without this callback leaked references, causing resource leaks and potential delays during hibernation restore. The fix ensures the DP capabilities are always read asynchronously, preventing reference leaks and reducing hibernation restore delays.
