The default remove path (hid_hw_stop -> hidinput_disconnect)\nonly iterates hdev->inputs, so input2 is never unregistered and leaks\non every device removal.\n\nAdd a .remove handler that stops the device first (preventing URB\ncallbacks from touching input2 during teardown) and then unregisters\ninput2.\n\n## Affected\n\n- `Linux >= 2562756dde550901c224e3805102bdfc17e7d13a < 1170ebfba562b3938ff7749b2e42e4420f19436d`\n- `Linux >= 2562756dde550901c224e3805102bdfc17e7d13a < aa4845a710ae9fee6a3831f5c338904cea77c3aa`\n- `Linux >= 2562756dde550901c224e3805102bdfc17e7d13a < 978e801750c7b0859e87eae619f7d88fcd88333e`\n- `Linux >= 2562756dde550901c224e3805102bdfc17e7d13a < aa9dde93e05a837645fdfd577eea71f0733f0694`\n- `Linux 4.8`\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":[]}
