It runs before hwmon_device_register_with_info(), so when\nthat registration fails, ccp_probe() returns with the files still in\nplace.  The HID core then frees ccp, and ccp_remove() is not called for a\nfailed probe, so nothing removes them later either.  Reading one of the\nfiles dereferences the freed pointer.\n\nCreate the debugfs entries only after the hwmon device has been\nregistered, so no failing path can leave them behind.\n\nThe two version queries stay where they are.  They send USB commands\nwithout holding ccp->mutex, which is only safe as long as nothing else\ncan call send_usb_cmd(); once the hwmon device is registered its\ncallbacks can do so concurrently.  Only the debugfs creation moves, and\nit is told which queries succeeded.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"sunlit","depthScore":3,"depthScoreParts":{"impact":2.8,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
