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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","score":5.5},"cwes":["CWE-401"],"references":["https://git.kernel.org/stable/c/614cb8c26c5aa53196ee9b211b76ee618b147d32","https://git.kernel.org/stable/c/c85f325d9ec3116b0d4ee9d5b76c26aea0ad5ce0","https://git.kernel.org/stable/c/fe80251152fed5b185f795ef2cd9f7fe9c3162e0"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T22:45:36.895656543+00:00"},"epss":{"cve":"CVE-2026-64013","score":0.00121,"percentile":0.01868,"date":"2026-10-25"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
