{"schema":"threatline.record/2","record":{"id":"CVE-2026-100079","aliases":[],"summary":"usb: typec: ucsi: unregister debugfs entries on teardown","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nusb: typec: ucsi: unregister debugfs entries on teardown\n\nucsi_register() creates per-instance debugfs entries, but\nucsi_unregister() keeps them around until ucsi_destroy().\n\nDrivers like ucsi_glink that unregister/register the same UCSI\ninstance across remoteproc restart then try to create an already\nexisting debugfs directory and log:\n\n  debugfs: 'pmic_glink.ucsi.0' already exists in 'ucsi'\n\nUnregister debugfs entries as part of ucsi_unregister(), and\nclear ucsi->debugfs after freeing it so repeated unregister\npaths remain safe.","categories":["Operating systems"],"product":"Linux","vendor":"Linux","ecosystem":null,"affected_ranges":[{"source":"CVE
