This might cause a WARN() in the handler.\n\nAvoid that by adding an \"unbinding\" flag to struct user_event which\nwill short circuit the handler.","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":[],"references":["https://git.kernel.org/stable/c/35485dad6e28f9b17884764d4692b1655cb848d0","https://git.kernel.org/stable/c/51c23bd691c0f1fb95b29731c356c6fd69925d17","https://git.kernel.org/stable/c/99e425032c6ec13584d3cd33846e0c7307501b47","https://git.kernel.org/stable/c/9e2d4b58c1da48a32905802aaeadba7084b46895","https://git.kernel.org/stable/c/35485dad6e28f9b17884764d4692b1655cb848d0"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T21:49:08.435428910+00:00"},"epss":{"cve":"CVE-2024-27067","score":0.00222,"percentile":0.12819,"date":"2026-10-31"},"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).
