Recommended response

  1. 1Check inventory. Check lockfiles and deployed manifests for Linux/Linux, Linux/Linux, Siemens/SIMATIC S7-1500 TM MFP - GNU/Linux subsystem.
  2. 2Review the reported fix. Update Linux/Linux to 727dee0857946b85232526de4f5a957fe163e89a; Siemens/SIMATIC S7-1500 TM MFP - GNU/Linux subsystem to * if you use the affected versions. Test the change in a non-production environment first.

Upstream source description

In the Linux kernel, the following vulnerability has been resolved: USB: gadget: f_midi: f_midi_complete to call queue_work When using USB MIDI, a lock is attempted to be acquired twice through a re-entrant call to f_midi_transmit, causing a deadlock. Fix it by using queue_work() to schedule the inner f_midi_transmit() via a high priority work queue from the completion handler.
