If registration fails, the\ncaller frees the charlcd object while delayed work still contains its\naddress.\n\nAdd charlcd_deinit() to cancel the delayed work and turn the backlight\noff. Use it for both registration rollback and normal unregistration.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":7.8},"cwes":[],"references":["https://git.kernel.org/stable/c/22586432c1aba89d9bd33f3173408dac830f220b","https://git.kernel.org/stable/c/6eaed64a32e550daf0dc9549742b3ab9e41d984f","https://git.kernel.org/stable/c/84858671842ae5857b9ed1202b62f9045373dcd1","https://git.kernel.org/stable/c/cd97b3c68fe3c06c8067cc59d7dff976c5b7ea04","https://git.kernel.org/stable/c/e3e3bf40916c1e810df03958cfa7ba6883cdce79"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:53:43.293028046+00:00"},"epss":{"cve":"CVE-2026-89585","score":0.00169,"percentile":0.06197,"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).
