This leads to leaking the notify handler past driver\nremoval, which may cause a kernel crash to occur if ACPI notify on\nthe given device is triggered after removing the driver, and causes a\nsubsequent probe of the given device with the same driver to fail.\n\nAddress this by updating the acpi_remove_notify_handler() call in\nacpi_button_remove() as appropriate.","published":"2026-07-19T16:17:41.000Z","lastModified":"2026-10-15T11:17:38.000Z","status":"Modified","sourceIdentifier":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","cvss":{"version":"3.1","score":5.5,"severity":"MEDIUM","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"},"cwe":["CWE-401"],"affected":["linux/linux kernel"],"epss":{"score":0.00121,"percentile":0.01876,"date":"2026-10-27","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"low","text":"Lower severity and a low EPSS score (0.12%).
