CVE-2026-100079
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.
