In the Linux kernel, the following vulnerability has been resolved: usb: typec: ucsi: unregister debugfs entries on teardown ucsi_register() creates per-instance debugfs entries, but ucsi_unregister() keeps them around until ucsi_destroy(). Drivers like ucsi_glink that unregister/register the same UCSI instance across remoteproc restart then try to create an already existing debugfs directory and log: debugfs: 'pmic_glink.ucsi.0' already exists in 'ucsi' Unregister debugfs entries as part of ucsi_unregister(), and clear ucsi->debugfs after freeing it so repeated unregister paths remain safe.
