Description
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.
Affected configurations
• linux linux kernel (>= 6.6 < 6.6.157)
• linux linux kernel (>= 6.7 < 6.12.110)
• linux linux kernel (>= 6.13 < 6.18.52)
• linux linux kernel (>= 6.19 < 7.2.6)
